    城市区域是经济全球化与区域一体化发展趋势下重要的空间组织形式,功能多中心是城市区域最为重要和本质的特征以及最为关键的演化阶段。以流动空间和城市网络理论为基础,城市区域功能多中心的研究可以从城际功能联系展开,通过定量测度与定性分析相结合的方式获得具有实践与理论意义的成果。以珠三角城市区域为研究对象,以城际轨道流为功能联系的数据基础,对珠三角城市区域的功能多中心进行探讨。研究表明,基于城际轨道交通流功能联系的珠江三角洲地区具有较高的功能多中心性,在世界上典型的城市区域中处于中上水平;对于东西两翼多中心度的测度与分析发现,东西两翼城市间缺乏有效的城际轨道交通功能联系,对于珠三角城市区域功能多中心产生严重的消极影响,珠三角城市区域功能多中心度进入离心发展阶段。随着城际轨道交通建设的推进和区域一体化的发展,珠三角城市区域的功能多中心将趋于成熟。


    Urban region is an important spatial organization form of economic globalization and regional integration trends. Functional polycentricity is the most essential features and the most critical stage of evolution to city region. In the flowing space and urban network theory, functional polycentricity study of urban regions can unfold from intercity functional connection with quantitative measurement and qualitative analysis approaches. In this article, the Zhujiang River Delta urban areas for the study, we carry on the discussion to the functional polycentricity of the Zhujiang River Delta region based on the data of intercity rail traffic flow. Research shows that, intercity rail traffic flow functional relation of the region has a high level of functional polycentricity of the Zhujiang River Delta which include in the middle and upper levels of typical cities or regions in the world. With the measurement and analysis of functional polycentripolycentriccity for the eastern and western wings, it shows that there lacks seffective intercity rail transportation contact between eastern and western wings, which has a serious negative impact on thefunctional polycentricity of the Zhujiang River Delta. The functional polycentricity development of the Zhujiang River Delta has entered the centrifugal stage. Along with the development of the intercity rail transit construction and regional integration, the region of the multifunctional center will tend to be mature.

    通过构建“不同历史时期特殊事件-城市空间结构”研究模式,以天津市为案例,把影响城市空间发展的要素与城市空间结构有机结合起来,解释城市空间结构演变的动力机制。以特殊事件为切入点,首先把影响天津城市空间演变的特殊事件分为七大要素:突发事件、经济政策、城市方针、城市规划、基础设施建设、土地制度和住房制度,这些要素决定了天津城市的经济发展、产业构成、城市发展规模、城市布局、空间发展走向以及城市土地利用效率和住宅类型与分布;然后通过分析各要素里的重大事件对天津城市空间演变的影响,找出各重大事件在天津城市空间结构演变中所扮演的角色,以期达到二者有机的统一。最后在此基础上,对未来天津城市空间结构的发展做了预测。


    Urban spatial structure is a hot topic in the urban geography and urban economy research. Theoretically, the evolution and mechanism of the urban spatial structure is affected by multiple factors, such as competition, rental, governor and relations of production, et al. Chinese scholars usually focus on the single factor influence in the urban spatial structure evolution and mechanism studies, and the connection between the factors and spatial has been ignored. Thus, according to reconstructing the model of “special events”, logically combining the urban spatial structure and factors affecting the urban development to understand the dynamic mechanism of the spatial structure evolution of Tianjin City in this article. Special event is the breakthrough point. Firstly, classifying the special events in different historical periods of spatial evolution in Tianjin into seven factors: spatial event, economy policy, urban development policy, urban planning, infrastructure, land system and housing system. They decide the economic development, industrial structure, urban development scale, urban distribution, spatial development trend, land use efficiency and house estate type and distribution, respectively. Secondly, according to the analyze the influence of special event in different historical periods to Tianjin spatial evolution in each factor, figured out the role of special events in the Tianjin spatial structure evolution. Finally, the development of Tianjin spatial structure in the future was predicted.

    Scientific evaluation of Marine ecosystem sustainable development ability is an important basic to grasp accurately whether healthy development of Marine ecosystem or not. In the Marine economy sustainable development concept, the sustainable development of Marine ecosystem is a foundation, and of great significance for human development. However, as the global population increases and an increase in the demand for resources, the Marine resources excessive consumption, and water eutrophication and serious consequences such as ecological variation, Marine ecosystems are under great pressure. Therefore, how to determine scientifically whether Marine ecosystem health development or not, has become an important problem under Marine economy sustainable development target. Large Marine ecosystem is an open system, which has the general characteristics of complex systems, such as open, dynamic, metabolic and adaptive. Marine ecosystem exchanges energy with the outside world, whose structure changes with the external disturbances and internal fluctuation change, and is a dynamic and stable ordered structure with a strong vitality. It has not only different pattern in the space and function, also shows a succession stage on time. Marine ecological system conforms to the characteristics of dissipative structure, and the change process shows the dissipative structure system characterized by the entropy change. The evaluation index system of sustainable development ability of Marine ecosystem was founded based on the characteristics of Marine ecosystem and understanding of Marine ecosystem sustainable development connotation. The sustainable development ability assessment model for Marine ecosystem was built up based on information entropy. The information entropy theory is based on probability and numerical statistics. Entropy in this article is a quantitative description of Marine ecosystem state, to evaluate Marine ecosystem sustainable development ability and the trend. Thus it analyzed various indexes' impacts on the sustainable development ability of Marine ecosystem. By establishing a model based on support input entropy, pressure output entropy, consumption metabolism entropy and restore metabolic entropy model , the evaluation for China's Marine ecosystem sustainable development ability was explored, so as to accurately grasp the Marine ecosystem health development, further to provide the references for government's guideline, and then put forward some countermeasures to promote Marine ecosystem sustainable development. The main conclusions of this study could be summarized as follows: 1) the requirements of Marine ecosystem on the natural ecosystem continuously grew; 2) under the attention of state and government, Marine pollution problems have been improved, and Marine ecosystem moves towards orderly and healthy direction; 3)the ability of the natural ecosystem to support continuously showed an increasing trend, and Marine ecosystem sustainable development ability was on the rise as a whole.

    为了科学地评价区域生态系统对经济与社会发展的服务支撑能力,引入生态系统服务理论等构建资源环境成本及绿色GDP核算、生态负荷强度模型,计算出中国31个省区2001~2012年的资源环境成本、生态负荷强度,在此基础上利用探索性空间数据分析方法对2001年以来中国省区的生态负荷强度随时间演变的趋势及其空间分布特征进行分析和探讨(港澳台除外)。结果表明,在研究时段内中国省区的资源环境成本由16.83×1012元攀升到25.24×1012元(2001年可比价),生态负荷强度由1.55下降到0.45;中国生态负荷强度呈西北、东部沿海地区集聚的空间分布特征,其中西北为高-高、东部沿海为低-低集聚区;这种西、东集聚现象的显著性在研究时段内逐渐减弱,空间负相关区域增加到11个、具有持续扩张的趋势,区域生态效益或经济效益持续向周边溢出。


    With the fast development of the national economy, the ecological pressures caused by economic development are continuously increasing. So it is necessary to make quantitative analysis for the status of China's resource consumption in the course of economic development. In order to scientifically evaluate the service and support capacity provided by regional ecosystem for economic and social development, the theory of ecosystem services was introduced to evaluate quantitatively resource consumption and the green GDP. Based on above-calculated values, the model of the ecological load intensity was established. In this article, taking 31 provincial districts in China as the samples(Hongkong, Macau and Taiwan excluding), the values of resource consumption and environmental loss costs for all provincial districts were firstly calculated by using ecosystem service values according to the interrelated data from 2001 to 2012. The green GDP for all provincial districts was further gained by combining the annual values of GDP. Moreover, the ecological load intensity for all provincial districts from 2001 to 2012 was computed in China. On the basis of above-mentioned issues, the Exploratory Spatial Data Analysis combined with GIS was used to study the temporal changing tendency and the spatial distributing characteristics of the ecological load intensity for all provincial districts since 2001. Furthermore, the spatial cluster and difference was analyzed and the corresponding influence factors were discussed. The above results showed that the values of resource consumption and environmental loss costs for all provincial districts were increasing yearly from ¥16.83×1012 in 2001 to ¥25.24×1012 in 2012. Meanwhile, the ecological load intensity for all provincial districts was decreasing yearly from 1.551 to 0.446. From 2001 to 2012 the ecological load intensity existed some spatial cluster and difference, however, the spatial cluster was appearing a weakening tendency with the time. The distribution of the ecological load intensity had a positive correlation characteristics, which meant that there existed a spatial cluster feature. The regions with HH (high-high) correlation pattern were mainly located in the west where resources were relatively rich. The regions with LL (low-low) correlation pattern were mainly located in the east where the economy was relatively developed. The spatial difference of the ecological load intensity exhibited mainly in the middle regions which had a negative correlation characteristics with circumjacent regions. The regions with negative correlation pattern had been increasing to 11. The ecological load intensity in these regions had an obvious diffusing tendency and ecological benefits were spilling over toward surrounding regions. In the future, it is still necessary to continuously advance and promote functional region programming, adjust area industry structure, check the performance of regional government, and so on. Some measures should be taken to gradually enhance utilization efficiency of resources, lower environmental loss costs and improve economic development quality.

    黑龙江省三江平原垦区是中国耕地规模最大的连片农垦区和第三大区际商品粮供应基地。近年来,随着这一地区工业化和城镇化进程的加快,如何科学的选择和建设区域的中心城市成为该区完善区域城镇体系和推进城镇化进程的紧迫任务和现实课题。基于此,应用改进的引力模型来计算县级单位与农场间的空间联系强度,界定出各县级单位的腹地范围,明确三江平原垦区的中心城市;以各农垦分局为研究单元,研究各农垦分局的碎化程度;通过明确县级单位拥有农场腹地数目,确定各农垦分局的中心城市;结果发现建三江、虎林、富锦、友谊和密山等宜作为三江平原垦区的中心城市;提出通过壮大中心城市的综合实力、推动场县共建和深化对外合作等措施来推动三江平原垦区城镇化进程。


    The Sanjiang plain reclamation area of Heilongjiang Province is the largest continuously arable area and the third-largest interregional commodity grain supply base of China. Recently, with the acceleration of regional industrialization and urbanization, the Sanjiang plain reclamation area faces challenges such as how to choose and construct regional central cities to build a reasonable urban system and promote the local urbanization process. Hence, the article focuses on choosing central cities in the Sanjiang plain reclamation area of Heilongjiang Province. The research content includes the following parts. Firstly, this research uses the modified gravitational model to calculate the spatial linkage capacity of the 24 county-level units (including 20 counties and 4 reclamation bureaus) to identify the hinterland delimitation of each county-level unit. Secondly, based on the former result, this article further studies the spatial structure features of each reclamation bureau by measuring the metropolitan fragmentation index. Thirdly, this article suggests that Jiansanjiang, Hulin, Fujin, Youyi and Mishan etc can be cultivated as potential central cities of each reclamation bureau. Last but not the least, in order to promote the urbanization process of the Sanjiang plain reclamation area, this research proposes that the Sanjiang plain reclamation area should improve the comprehensive strength of central cities, strengthen the cooperation relationship between state farms and local governments, and deepen the local opening-up degree.

    历史时期全球化作用下的城市空间转变——以1890s~1930s广州东山地区为例
    薛德升,黄鹤绵,王阳
    地理科学. 2014, 34 (6): 687-695.   DOI: 10.13249/j.cnki.sgs.2014.06.687
    摘要   HTML   PDF (864KB)

    世界城市历史研究作为新兴的研究领域,虽然突破了世界城市经典理论的“现代主义”视角,证明全球化对城市空间转变的作用具有长期性,但仍局限在“经济主义”的分析范畴之内,将经济因素视为决定性动力。20世纪初期,广州东山地区完成由“乡村地区”向“社会精英阶层居住地”的空间转变,促使城市空间格局由“东村西富”变为“东贵西富”。这场具有历史意义的空间转变是教会、华侨、政府、官僚4种动力相互作用、相继推动的结果。东山地区的发展历史表明,除经济联系外,城市的全球文化联系对空间转变同样具有重要推动作用。在一些特定的城市或城市中的特定地区,社会文化动力对城市空间转变具有决定性的作用。


    Criticizing the classical world city theories as “presentism”, the historical studies of world cities have become emerging research subjects in this new century. Although many researches have examined the spatial transformation of world cities in a “long-term” perspective, few lights are shed on the cultural, social and political elements. Using the historical materials, such as maps, literatures and reports, this article chooses Dongshan, a well-known historical district in the east side of Guangzhou, as a case, and attempts to rediscover its spatial transformation in globalization at the turn of the 19th and 20th centuries. It finds that, in the historical period, the transformation of Dongshan, from village to residential area of bureaucratic elites, extends the urban area sharply and changes the spatial structure of the whole city. Four kinds of dynamics are identified and integrated as a special model in promoting the spatial transformation: 1) The Christianity, as the beginning one, invests in the district first and provides medical and educational facilities to returnees and bureaucratic elites; 2) The oversea Chinese, as the basic one, chooses to dwell here and provides capital to the Christianity and governmental projects; 3) The government, as the guiding one, promotes modern urban planning to reshape the space and plays as a policy constitutor. Its permissions for mission work and encouragement in investment from overseas Chinese are crucial for the former two dynamics; 4) The bureaucratic elites build houses here and finally create the image of the district as a prosperous place. The story of Dongshan could challenge the classical world city theories in three aspects: 1) It provides a Chinese case to prove the importance of historical views again; 2) Not just global economic links, the global cultural factors, such as the Christianity, the cultural links between overseas Chinese and homeland, could also promote urban developments. The economic variable is not as decisive as Friedmann argues; 3) Especially in Chinese cities, the role of government and bureaucratic elites are important, but neglected in classical theories. Influenced by the classical theories, most of the historical studies on world cities still focus on the economic factors, this article attempts to argue that, non-economic factors, including cultural, social and political ones, should be involved in future analysis.

    土地利用变化对生物多样性和生态过程有着深刻的影响,与城乡景观格局变化密切相关。尝试将土地利用变化驱动力——土地经济生态位的理论和方法引入到景观生态学当中,为城乡空间景观格局空间表征提供新的方法。通过选取表征景观格局指标的破碎化指数、分形维数,利用Envi4.8、Arcmap10.0,Fragstasts4.1等软件,以广东省惠州市为例,在分析土地经济生态位与景观类型、景观指数之间的关系基础上,对土地经济生态位变化下的城乡空间景观格局进行表征。结果表明:不同景观土地面积数量的增减与该类型土地经济生态位升降具有一致性的规律,土地经济生态位上升,相应的景观土地面积增大,反之则减小;土地经济生态位越小,表征景观格局的景观破碎化指数、分维数指数越大,破碎化指数与分维数指数的增减与土地经济生态位升降表现出一致性的规律,土地经济生态位上升,相应的破碎化指数、分维数指数则增大,反之则减小;城乡空间景观格局变化的发生主要出现在土地经济生态位高的区域。土地经济生态位的变化是城乡景观格局变化的重要影响因子,能够很好解释城乡空间景观格局特征。


    The land use change has profoundly impact on biodiversity and ecological processes, and is closely related to the change of the rural and urban landscape pattern. As the driving force of land use, the theory of land economic niche was used to analyze the rural and urban landscape pattern in this article, with an aim to provide some new methods for the characterization and representation of landscape pattern. The typical parameters of landscape pattern including fragmentation index and fractal dimension were selected, and the software Envi 4.8(RS), Arcmap 10.0(GIS) and Fragstasts 4.1 were used, to discuss the relationship between the land economic niche, also its change, and the urban and rural spatial landscape pattern in Huizhou City, Guangdong Province. Results showed that the changes of different landscape land area corresponded well with those of land economic niche, when the land economic niche increased, the corresponding landscape land area also increased and vice versa. The smaller the land economic niche was , the bigger the fragmentation and fractal dimension index were. Meanwhile, the changes of fragmentation index and fractal dimension index corresponded well with that of land economic niche, where the land economic niche increased, the fragmentation index and fractal dimension index increased correspondingly and vice versa. The change of urban and rural space landscape pattern occurred mainly in areas with high land economic niche. The land economic niche is an important factor affecting the change of landscape pattern in urban and rural areas. The variance of the land economic niche can well explain the urban and rural spatial landscape pattern characteristics.

    Vulnerability of human-sea system is a research frontier in regional sustainable development. Vulnerability analysis is not only an effective tool in the realms of global environmental change and sustainability science, but also provides a new paradigm for the study of interaction mechanisms and processes of coupled human-land system. Studies carry out in human-sea system are of significance to not only the enrichment of the theories of human-land system, but also marine sustainable development. Based on human-sea system theory, combined with the theory of geography, economics and oceanography, the vulnerability framework to search the vulnerability of human-sea economic system is the focus in sustainable development of global marine, key process and dynamical mechanism. Vulnerability is considered as functional relationships between sensitivity and coping ability, this article, by constructing a vulnerability assessment model of entropy theory and function model, carries out a vulnerability research of the human-sea economic system in Liaoning regional area. Human-sea economic system studies the structure characteristics and rules of evolution in geographical space within the scope of the marine industry, and it contains a combination of various factors in sea and land which includes the regional, comprehensive, coordinated and sustainable features. It shows that: 1) the vulnerability of Liaoning coastal area in human-sea economic system declined year by year from 1996 to 2009, and from the strong vulnerability to weak one. 2) from the sensitive indexes, it showed a trend of “inverted U”. The junctions of the "inverted U" happened in 1999, 2001, 2004, and in 2006. Since 2006, the proportion of ocean GDP declined year by year. 3) from the coping ability indexes, it showed the steady grow. The added value of Marine industry increased year by year, offshore oil and gas industry development change by volatility, and marine fishing production get control in degree. In addition, the structure of Marine industry had some adjustment, and sped up the development of new industry. In the development of marine industry, marine chemical products production, shipbuilding and transportation are all important. So we can reduce the vulnerability of human-sea economic system from these aspects. Human-sea system includes three subsystems that are human-sea resources environment subsystem, human-sea economic subsystem and human-sea society subsystem. The coupling analysis of these three subsystems is also important. Then it obtains the vulnerability characteristics and the countermeasures of sustainable development, and it is another research direction in the future.

    地理科学. 2014, 34 (6): 717-724.   DOI: 10.13249/j.cnki.sgs.2014.06.717
    摘要   HTML   PDF (546KB)

    以珠江三角洲为研究对象,在分析2000~2010年其污染产业空间分布特征的基础上,采用面板数据的计量模型进行实证研究。首先通过模型分析发现各环境管制因子中工业SO2排放量的管制程度显著影响污染产业的空间分布;然后再将此环境管制因子运用到分行业模型中,发现非金属制品业、水电煤气生产业、造纸及纸制品业等产业分布与宽松的环境管制相关,化学工业和黑色金属行业则与环境管制无关。最后,认为环境管制已成为影响中国污染产业空间分布的重要因素,在中国环境管制手段以“命令控制型”为主和地方分权的背景下,不同的环境管制手段将对该手段实施后影响程度大的污染行业的空间分布产生影响。


    In this article, we focus on the spatial distribution of pollution industries in the Pearl River Delta (hereinafter referred to as PRD) by using the panel data during the period of 2000-2010. Firstly, the temporal and spatial pattern of pollution industries was analyzed. The speed of pollution industry development shows as an “S” shape. Nonmetallic industrial enterprises, among others, have dramatically relocated to the non-PRD area from the PRD area. Within the PRD area, the spatial pattern of pollution industries have shifted, with Foshan and Guangzhou entering the first-tier while Shenzhen and Dongguan in the second. For different types of pollution industries, the spatial-temporal dynamics is more complex and intricate. Panel data model is further used to find out whether environmental regulation is related to the spatial distribution of pollution industries, and if so, which kind of environmental regulation is at work. According to Weber's industrial location theory, the model is built with the proportion of the pollution industries output to those in Guangdong Province as the dependent variable, and the independent variables consider factors that influence the spatial distribution of the pollution industries, such as capital, wage rate, transportation, agglomeration and environmental regulation. Among others, the variable of environmental regulation is the focal one for our investigation, the proxy of which is four different indicators, namely the ratio of sulfur dioxide emissions to the provincial average value, the ratio of industrial waste water to the provincial average value, the utilization rate of solid waste, and the year of getting the award for the model city for environmental protection. The results show that higher level of sulfur dioxide emissions, which indicates looser regulative control on air pollution, boosts the agglomeration of pollution industries, while the other variables for environmental regulation do not demonstrate significant impact. In what follows, we bring the ratio of sulfur dioxide emissions to the average as the single variable for environmental regulation into the sector-specific panel data model, and discovers that the spatial distribution of pollution industry sector such as nonmetallic industry, water and electricity gas industry and paper-making industry are significantly influenced by environmental regulation, while other industries such as ferrous metal industry and chemical industry are unaffected by the environmental regulation. This result shows that China's energy saving and emission reduction policy which includes the sulfur dioxide emission reduction targets do work for the heavily air-polluting industries. Finally, the article concludes with the following two points concerning the mechanism of environmental regulations for the location of pollution industries. 1) Environmental regulation has been an important location factor in China, inasmuch as the local governments hope to upgrade the local industries with the help of environmental regulations under the context of fiscal decentralization. 2) The impact of environmental regulations on industry location depends not only on the industry character, but in the Chinese context also on the regulative means aimed for specific environmental goals.

    伴随城市空间向郊区急剧扩张,郊区已成为快速城市化过程中疏解城市人口和功能的重要空间。作为兼顾工作与家庭的双重工作者,郊区女性居民的日常生活面临着新的挑战。基于2012年北京居民日常活动与交通出行调查的第一手资料,采用时间地理学研究框架,以一周的活动日志数据为基础,从时间节奏和时间分配的角度分析郊区女性的时间利用特征,并通过标准置信椭圆对GPS轨迹数据进行了活动空间刻画,探讨不同活动在城市不同空间中的发生日间差异。结果表明,在时间上,郊区女性的日常生活具有规律性、丰富性和细碎性的特点;工作日的时间分配以工作活动为中心,从周一到周四的差异性不显著;休息日的时间分配以家务和休闲活动为主,并且在休息日内部出现周日出行时间相对较少的差异。在空间上,大部分郊区女性居民选择在郊区附近就业,日常生活中的购物、休闲活动也主要在郊区空间发生;在休息日,购物活动向城区空间内延伸,休闲活动的空间范围虽然相比于工作日有所扩大但仍主要在郊区空间内部完成。


    The rapid growth of urban population in China, together with the dramatic institutional transition, has led to the fast spreading of urban space and a growing tendency of residential suburbanization. Remarkable environmental changes have taken place in urban China, with large suburban residential areas emerging in big Chinese cities. As often observed in urban China, the dwelling environment of suburban areas is distinct from downtowns with less job opportunities and insufficient facilities, resulting in longer distance in daily trips and disadvantages in residents′ accessibility. For the female population particularly, despite more engagement in labor market and possibility of economic independency thanks to the improvement of women′s status in the past decades, most of them keep taking responsibility for domestic duty resulting from the traditional family value, and thus suffer more challenges in daily life in the context of dramatic urban sprawl compared with the male counterpart. Few studies have addressed the gendered activity pattern in suburban China, urging for attempts to reveal the gender inequity and the ignorance of women′s wellbeing in the development of suburban areas.This study based on a GPS-based activity-travel survey in Beijing in 2012, applies a time-geographic research framework and a feminist perspective to explore the activity pattern and day-to-day variability in activity-travel behavior of suburban women in both spatial and temporal dimensions as an attempt to reveal the gendered activity space in suburban China. Emphasis is put on daily rhythms and time allocation of activities based on the activity-travel diaries, and GIS-based activity space based on the standard confidence ellipse analysis of GPS data. On the one hand, in the aspect of time, it is observed that the daily life of the suburban women tends to be regular, diversified and fragmental in terms of time use. On weekdays specifically, working activities constitute a dominant part in time allocation, and the participation of shopping, housework, travel and leisure activities is relatively fixed with insignificant variation from Monday to Thursday and a slight augmentation in housework activities on Friday; while on weekends, housework and leisure activities constitute a greater part in time use, and less time is allocated to trips on Sunday compared with Saturday. On the other hand, in the aspect of space, it is found that the majority of the suburban female residents are employed in the inner suburban areas, and most of the non-work activities take place in suburb with an exception of shopping activities on weekends. It could be concluded that the suburban areas in Beijing, while being gradually shifting from dwelling space to living space for suburban female residents, still need further promotion in job opportunities and shopping facilities. The results from the study shed light on the weekly space-time behavior pattern of suburban female residents, and provide beneficial implications for spatial planning and infrastructure construction in the suburban areas addressing the gender equity and women′s quality of life.

    以南京市高淳区东坝镇土地整治项目为实验区,基于格局-过程-效应的视角,运用最小累积阻力模型分析土地整治对生态连通性的影响及生态格局优化途径。结果显示:① 从景观格局看,土地整治后生态景观破碎度降低,集聚度上升,较整治前更规整,但景观优势、空间连接度和多样性指数下降,不利于整个生态系统的自组织能力与可持续发展;② 从景观过程看,土地整治后原有的生态廊道被侵占和阻断,景观生态服务功能和强度均弱化。③ 从景观效应看,土地整治后生态功能连通性降低,生态流阻隔,形成明显的3个“生态孤岛”。因此,研究区在整治过程中需注意保护东-西方向生态流迁移关键通道和南-北方向、西南-东北方向辅助通道的畅通,努力优化整治区生态格局。


    China has witnessed an explosive rise in the demand for construction lands in recent decades in conjunction with its rapid urbanization and industrialization.This intensifies the contradictions between construction land expansion and arable land protection. Fortunately,land consolidation has been proposed and carried out since 1990s, which made the aforementioned situation better. Meanwhile, it seems to yield many new issues on ecology which might be side-effect.As it is accepted that land consolidation is an artificial transformation of land ecological system, which can not only change the composition and structure of ecological land, but deeply affect the material cycling, energy flow and ecological process of landscape elements.Therefore, itchanges the connectivity and function of ecological land. From the perspective of pattern-process-effect, a case study of land consolidation project in Dongba Town, Gaochun District,Nanjing was analyzed for the impact of land consolidation on ecological connectivity and its pattern optimization based on the minimum cumulative resistance model which would be called MCR model hereafter. Whereas attempts for MCR model has been made for many realms such as ecological security assessment, urban growth boundary definition, landscape pattern optimization, etc., few such spatially explicit MCR model for land consolidation impact has been devised. The analysis might provide an alternative and quantitative perspective of this field and subsequently deepen understanding of the fact that in which way and to which extent land consolidation alters the ecological connectivity. The results showed that: 1) With regards to landscape pattern, the ecological landscape fragmentation decreased from 1.32 to 1.19 while the aggregation index increased from 97.78 to 98.13 during land consolidation. This suggests that more regular ecological patches. However, the landscape dominance index, space connectivity and diversity index declined, which could indicate unfavorable impact on the ability of self-organization and sustainable development of the whole ecosystem. 2) With regards to landscape process, the original ecological corridors were occupied and blocked after land consolidation landscape, making the ecological service function and service strength weakened. It was mainly attributed to the losses of pit-ponds as well as canals which were crucial channels for energy flow, material cycling and exchange. 3) With regards to landscape effect, ecological functional connectivity reduced after land consolidation as the mean of regional resistance value ascended from 498.16 to 761.35 and the maximum increased from 7389.21 to 8987.28. A threshold value of 927 according to the natural break point was employed to pick out the hotspots of connectivity reduction area. As a consequence, it is salient to see the formation of three "ecological islands", more explicitly indicating where the ecological flow was blocked much. Therefore, much more attention should be paid to protect the key channel and auxiliary channels for ecological flow to optimize the ecological pattern.

    利用2008年锦州玉米农田生态系统野外观测站资料对CoLM与BATS1e模型模拟能力进行定量评价。比较发现: 两模型对净辐射和表层土壤温度的模拟精度都较高且差异不大,CoLM模型对感热、潜热、土壤热通量、次表层土壤温度模拟能力都不同程度高于BATS1e模型,模拟值对实测值解释能力分别偏高3%、22%、1%、10%,NS (Nash-sutcliffe效率系数)分别偏高1.042、0.266、0.023、0.138。从各月情况看,两模型在7月对感热、潜热模拟能力都较高,而在其它月份CoLM模型模拟精度明显高于BATS1e模型,土壤热通量和次表层土壤温度在5~8月前者模拟精度高于后者。由于CoLM模型对潜热更高精度的模拟可证明其对表层土壤湿度模拟精度高于BATS1e模型。


    Using observations data in 2008 from Jinzhou Agricultural Ecosystem Research Station, land surface process models performance between CoLM and BATS1e were evaluated and compared. The results show that net radiation and surface soil temperature are both able to be accurately simulated with a very small difference between the two models. Model performance of CoLM is higher in different degrees than BATS1e for simulations of sensible, latent, soil heat fluxes and subsurface soil temperature with interpreting ability of simulations to observations and Nash-sutcliffe coefficient of efficiency factor of the former being 3%,22%,1%,10% and 1.042,0.266,0.023,0.138 higher than those of the later, respectively. As far as every month is concerned, simulation precisions of sensible and latent heat fluxes in most months except July when two models work very well as well as soil heat fluxes and subsurface soil temperature from May to August are higher for CoLM than BATS1e. Besides, it will be proved that Model performance of CoLM for simulation of surface soil water content is also higher than that of BATS1e because of its more accurate simulation for latent heat flux.

    以长白山北坡林线长白落叶松(Larix olgensis)和岳桦(Betula ermanii)为研究对象,通过野外样方调查、树轮技术分析,采用趋势线模型拟和、单因素方差等统计方法从各种参数分析长白落叶松和岳桦径向树高生长的对比关系并揭示2个种群动态对环境适应性的对比差异。结果显示:垫状生长形的长白落叶松海拔最高(均值:2 017 m),其次为旗形树(2 005 m),正常形态的海拔最低(1 992 m),所在生境差异显著(p < 0.05)。正常形态的长白落叶松生长速度大于岳桦(树高方程斜率:长白落叶松0.750 9>岳桦0.253 6),随着旗形树的出现,速度相似(斜率:长白落叶松0.375 4>岳桦0.253 6),变成垫状后,岳桦占优。长白落叶松受到压制种群扩张速度不如岳桦,长白山林线上侵表现为以岳桦种群为主力,长白落叶松仍是岳桦主要的伴生树种。


    The aim of this article is to understand the different responses between Laris olgensis and Betula ermanii to environment adaptability on north slopes treeline of the Changbai Mountains. The alpine treeline is regarded as highly sensitive and a potential indicator of environmental change and it has thus become one of the hotspots of environmental change research. Most researches on treeline dynamics have been conducted at a population scale, and there have been comparatively few studies of treeline dynamics at multi-population. In this study, treeline dynamics were analyzed at two populations in the Changbai Mountains by examining the change in relationship between two population’s dynamics and the environment. The treeline of the northern slope of the Changbai Mountains was selected as the study area. Data source was obtained by field investigation and tree-ring analysis. The altitude differences of three growth forms (general tree, flag tree and cushion) of Laris olgensis were revealed by half-peak width, mean ± standard deviation, and One-way ANOVA. DBH (diameter at breast height) of each tree (Laris olgensis and Betula ermanii) was measured by measuring tape (precision: 0.1 cm) and 142 cores were taken from the living trees in plots. The ages of the sampling trees were known using tree-ring and the age-class (DBH) regressions were created to estimate ages of all trees in the plots. The annual stem recruitments of Laris olgensis and Betula ermanii populations were calculated based on field investigations. The difference of growth rates between Laris olgensis and Betula ermanii was understood by assessing differences in the slopes of trend lines and paired-samples T test. The different responses to environmental change between Laris olgensis and Betula ermanii were evaluated using mathematical models. The results showed that cushion growth form of Laris olgensis situated in the highest habitat, followed by flag tree and general tree in the lowest habitat. There were significant differences among three habitats of growth forms of Laris olgensis (p<0.05). The growth velocity of diameter and height growth of Laris olgensis with general growth form was higher than that of Betula ermanii. The difference was not significant between Laris olgensis and Betula ermanii when Laris olgensis changed flag tree. However, Laris olgensis was lower than Betula ermanii when it changed cushion growth form. Population expansions of Laris olgensis and Betula ermanii were very obvious as temperature increase. Expension velocity of Laris olgensis was lower than that of Betula ermanii because it was pressed by Betula ermanii. The growth velocity of all growth forms of Laris olgensis was lower than that of Betula ermanii when tree ages were less than 13 years. Treeline shift was caused mainly by population expansion of Betula ermanii. Laris olgensis was still main accompanying tree specie of Betula ermanii. However, Laris olgensis may become pure forest when Betula ermanii was cut down in quantity.

    查干湖湿地是吉林西部重要的生态屏障,分析其水环境演变特征,可为保障其水环境安全提供科学依据。利用1982~2011年的水位资料和1985~2011年的水质资料分析其水环境演变特征,采用卡尔森指数法和模糊综合评价法对查干湖湿地进行综合营养状态和水质状况评价。结果显示引松工程通水后湿地水位得以恢复并稳定在129.8~130.3 m;20世纪80年代末湿地水环境大幅改善,水体盐碱化、富营养化、有机污染得以缓解,但2006年以来水质碱化和有机污染加剧,水质由Ⅲ类演变为IV类。现阶段农田退水缓解了主湖区的碱化且暂未加剧其水体富营养化。查干湖水受流域陆源排放、湖泊内源释放及水文情势等多重因素的交互作用,呈以磷素为限制的中营养状态,应控制区域生活污水和畜禽粪便的污染以保护其水环境健康。


    Chagan Lake wetland is an important ecological barrier of the western Jilin Province. Analyzing the evolutional characteristics of the water environment will provide a scientific basis for the protection of the water environment security. The evolvement of water environment was comprehensively studied through analyzing the water level data from 1982 to 2011 and the water quality data in 1985-2011. Carlson trophic state index (TSI) and the fuzzy comprehensive evaluation method were used to assess the eutrophication level and the water quality. The results showed the water level was recovered and stabilized at 129.8-130.3 m after the operation of the channel transferring water from Songhua river to Chagan Lake. Water salinization, eutrophication, organic pollution were mitigated and the water environment improved considerably in the late 1980s, but the trend of alkalization and organic pollution has became serious since 2006 and the water quality evolved from Ⅲ category to IV category. The trend of eutrophication has been relieved since 2006. Agriculture drainage has relieved the water salinization and hasn't aggravated the level of eutrophication in Chagan Lake temporarily. The water quality of Chagan Lake is accross-affected by terrestrial emissions in the catchment, endogenous releases and hydrological regimes and exhibits a remarkable phosphorus limited middle nutrition. Sewage and animals' feces pollution should be controlled to protect the water environment health.
