    改革开放以来,山东半岛各城市迅速发展,极大推动了全省国民经济的发展,但与此同时,经济、环境与社会效益之间的矛盾也日趋激化。在分析该区主要人地关系问题的基础上,探讨生态环境与经济发展之间的相互关系,利用系统动力学模型进行多方案动态仿真模拟,进而利用协调发展度模型对各方案环境与经济协调发展程度进行定量评判,得出相对较优的发展方案,为该区协调发展提供战略决策依据。
    The coordinative development between eco-environment and economy is very important for area's progress. The Shandong Peninsula Megalopolis develops rapidly since the reform and open-door policy, greatly promoting the national economic growth of Shandong Province. But coincidently, problems among economy, environment and social benefit become more and more acute, especially those about resources and environment pollution. There is a large number of population in Shandong Peninsula megalopolis, and at the same time, more people immigrate into this area with the pace of development and economic expansion, which will exert huge pressure on resources and environment, resulting into the descending of environment carrying capacity. As far as the resources problems are concerned, water resources has become the main bottleneck of regional economic and social development in this area-the water possessed by each person is less than one sixth of the average level in China. The energy consumption in Shandong Peninsula megalopolis is mainly relying on coal, and thus will not only accelerate the scarcity of energy but also bring about a series of environment problems such as water pollution , air pollution, ect. The realization of sustainable development of megalopolis must be on the basis of the coordinative development of urban economy, population, resources and environment. So it is necessary to take the Shandong Peninsula megalopolis into account as one system composed of four subsystems mentioned above. Based on the analysis on the central problems between human beings and the earth, this paper studies the interrelationship among these subsystems, establishes the multi-pattern simulation model by use of the System Dynamics, which consists of 151 indexes including 7 level variables, 11 rate variables, 76 auxiliary variables, 15 table variables and 42 parameters. According to the present situation and the interrelationship of Shandong Peninsula megalopolis, the model selects six indexes as dominant parameters to determine the patterns simulating the process of eco-environment and social economy development in this area. There are four patterns in all. In the first one, the original value of the dominant parameters is the natural state of this area in 2003, while the other three are regulated to different extent. In order to attain the relatively sustainable development pattern of Shandong Pennisula patterns in the following 20 years, the paper quantitatively judges each pattern according to the coordinative degree model. In the model, 8 indexes such as the gross domestic product per capita, total production value of agriculture, total production value of industry, the investment efficiency of the three industries, the capital asserts investment, the outlay of research and development, ect., are selected to reflect the social economy development situation, while five counterparts, such as waste water, are chosen to reflect the eco-environment situation in this area. After the evaluation by the coordinative degree model, we can intuitively find that the fourth patterns is the relatively better one, which not only attaches importance to economic development but also thinks much of the resources and environment, while the other three regards only one aspect. Furthermore, the paper gives several brief measures to guide how to realize the relatively better pattern in the following 20 years.

    生态旅游是一项新的旅游活动、一项新的产业,是社会经济发展到一定阶段的产物。生态旅游的开发是一个循序渐进的过程,产业的发展存在着初级阶段、发展阶段和成熟阶段。结合四川社会经济发展水平和生态旅游资源分布规律,四川生态旅游形式应具有一定的时空特征,表现为时间上的阶段性和空间上的差异性,即在同一时期的不同地区或同一地区的不同发展阶段同时存在三种形式的生态旅游:泛生态旅游、准生态旅游、纯生态旅游。
    With social and economic development, eco-tourism has become a new tendency in China. As the tourism production of post industrialization society, eco-tourism industry development in Sichuan Province will face the great challenges from the lower level of economic development, little consumption market and lagged service system of tourism spots. How to develop the eco-tourism, this paper presents some useful conception: eco-tourism industry development is an evolution course, which is an integration of fluctuation in temporal dimension and disparity in spatial dimension, and eco-tourism can be divided into three hierarchies or stages: primary eco-tourism, semi eco-tourism, pure eco-tourism.

    元胞自动机CA越来越多地被用于模拟复杂的城市系统,但这些模拟基本不考虑城市的发展密度。不同的城市发展密度会对城市的形态有很大的影响,有必要将城市的发展密度引进CA的城市模拟中,以获得更好的模拟结果。本文将密度梯度函数引进了CA模型的转换规则中,并定义'灰度’来反映状态的转换。利用该模型对不同可能的城市发展组合进行了模拟,为城市规划提供了辅助依据。
    Most CA urban models assume densities to be uniform for all cells. This is not true in real cities because densities substantially vary from cities to cities and from urban centres to periphery areas. Development density which affects urban form is an important factor in urban planning. This paper presents a CA model that incorporates density gradient for the simulation of urban development of different urban forms. Development density is obtained from density decay functions and assigned to the cells when they are converted into developed ones according to CA transition rules. The model which is based on the concept of "grey cells" can be used as a planning model to explore various combinations of urban forms and development densities. This paper also evaluates and compares the development patterns generated by different density gradients. It is found that development scenarios with high-density development can significantly reduce the encroachment on agricultural land and other important environmentally sensitive areas.

    中国西南喀斯特山区由于地质背景和地貌结构的特殊性,致使三水转化与水资源形成过程不同于非喀斯特山区。文章探讨该区三水转化机理、水资源补给方式和形成过程,得出喀斯特流域对于相同或相似降雨过程的响应,不同的流域结构决定了补给方式、三水转化、径流调蓄和输移特征。提出喀斯特山区水资源合理利用模式应按照因地制宜、因土制宜、因水制宜及因需制宜原则,采用以小微型为主的水资源开发利用模式,实施分散拦蓄、分散供水,以化整为零方式解决喀斯特山区的整体性干旱缺水。
    Because of the particularity of geological and geomorphologic structure in karst mountainous area in Southwest China, the formation processes of water resources and the transform of rainfall, surface water and underground water are different from other areas. In this paper, the transform mechanisms of rainfall, surface water and underground water are discussed and the replenishment models of water resources and the formation of karst water are analyzed. As a conclusion, the responses of rainfall-runoff in different karst basins under the homology or similar rainfall processes are different. The replenishment models of water resources, the transform mechanisms of rainfall, surface water and underground water, the storage of water resources and the runoff transportations dominate the karst basin structures. For reasonably using water resources and settling the lack of water in karst mountainous area, the models of water use are put forward. According to the principles of water supply, there are different models of water resources use in different instances. The small water supply projects are primary models in karst mountainous area. The separate water obstructs and storage, the separate water supply and breaking up the whole into parts are recommended models of water resources use in karst mountainous area.

    Through intensive study on pollen and spores from the cores of Hm, Dh1 and G2 at the eastern part of Shanghai, six palynological assemblages and three sub-assemblages were distinguished. There are six stages of the evolution of vegetation and climate, which were reconstructed for the Late Quaternary on this area as follows: mixed sparse forest of conifers and deciduous broad-leave trees, reflecting the cold and a little wet climate (late stage of Late Pleistocene); forest of deciduous broad-leave trees with Pinus,Taxodiaceae-grassland, reflecting a temperate and little wet climate(sub-arctic period); mixed forest of conifers and broad-leave trees with a few evergreen broad-leave trees, reflecting a temperate and slightly dry climate(Boreal period); evergreen broad-leave forest being mainly composed of Quercus(evergreen) and Castanopsis, indicating a hot and moist climate(Atlantic period); mixed forest of conifers and broad-leave trees, indicated by Quercus, Pinus and Gramineae as main element in palynological assemblages, reflecting a warm and little dry climate (Sub-Boreal period); mixed forest of deciduous broad-leaves, evergreen broad-leaves and conifers, Quercus (deciduous, evergreen) and pines, being the main components, reflecting a warm and wet climate (Sub-Atlantic period). These fluctuations coincide with the global climatic changes. The study provides reliable evidence for the division and comparison of the age of the sediment at this region, also for the biostratigraphy and reconstructions of paleovegetaton, paleoclimate and paleoenvironment in this area since the Late Quaternary.

    对陇西盆地六盘山西侧山麓剥蚀面上断岘剖面的古地磁、磁化率和粒度分析表明,该剖面具有1.8 Ma B.P.以来完整的黄土-古土壤沉积序列。断岘剖面以下7级黄河阶地的发育形成以及在1.1和0.8 Ma B.P.前后所指示的腾格里沙漠扩张变化,反映了第四纪早更新世以来青藏高原阶段性隆升对黄土高原西部环境变化影响,以及在青藏高原隆升过程中构造与气候的变化与耦合响应。
    Analyses of paleomagnetic polarity reversals, magnetic susceptibility and grain size on the loess-paleosol sequence of Duanxian section, at a pediment of Longxi Basin lying to the west of Liupan Mountain show that this sequence contains most of the stratigraphic units recorded in the standard loess-paleosol of section on the China Loess Plateau over the past 1.8Ma. Research suggests that the loess-paleosol sequence of Duanxian section has seven terraces and a preliminary study on it finds that during the past 1.8Ma, there were two important climatic events indicating the advance of Tengger Desert. The events occurred at about 1.1and 0.8 Ma B.P., respectively. These not only reflect effect of uplift of the Tibetan Plateau in the late Cenozoic on the environment of the western Loess Plateau, but also record details of the coupling effect between tectonics and climate responses of this area to the East Asian monsoon.

    以黄土高原腹地泾河流域12个水文特征指标为"物种", 选取对流域径流有影响的9个环境因子, 采用DCCA排序方法定量分析河流径流特征沿环境因子梯度的演变规律。结果表明:(1)DCCA排序的前3轴分别与退化草地比率、降水量、降水强度、植被指数、平均坡度显著相关; (2)河流径流特征沿环境梯度可明显分为输沙量极大的北部黄土丘陵区;平均含沙量极高的中北部黄土沟壑区;径流量大、输沙量小的山地-沟壑过渡区;侵蚀模数极高、径流年内变化极大的中部黄土残塬区;产流量大、年含沙量极低的南部山地区。
    Twelve watersheds were taken as sample plots, 12 runoff characteristics indices were taken as "species "and nine factors were taken as environment factors in Jinghe basin on Loess Plateau. Based on that, a DCCA was used to quantitatively analyze the environmental roles and their effects on the spatial patterns of runoff characteristics. The results are as follows: (1) The first three axes of DCCA order relate to degraded grass land area ratio, rainoff, precipitation intensity, vegetation index and average slope significantly. (2)The runoff characteristics change slowly with environmental gradient and the basin can be divided into five runoff regions based on this. They are north loess hilly region, middle-north loess gully region, middle fragmentary loess plateau region, south mountain region and transition region from mountain to loess gully. (3) Twelve runoff characteristics index show different importance in different regions. Sediment transport ratio and sediment content are the most important in the north loess hilly region and north gully region. Extremely variation of runoff and erosion modulus are main indices in the middle fragmentary loess plateau region. Runoff, the biggest runoff index, the biggest sediment transport index, variation of runoff, variation of sediment transport are very important in the transition region from mountain to loess gully, and runoff modulus, runoff depth and the biggest sediment content index are main indices in the south mountain region.

    公路建设引起的人为加速侵蚀对生态环境造成很大影响,为摸清道路边坡的侵蚀规律,在青藏公路边坡布设了自然径流观测小区,降雨过后进行采样,获得径流深和侵蚀模数数据。对所得数据整理分析表明:(1)次径流深、次侵蚀模数与降雨量和降雨强度的乘积有很好的线性相关,相关系数分别为0.802和0.554。次径流深与次侵蚀模数之间的相关系数达到0.771;(2)产流产沙随坡长增加有减少的趋势,但其规律还有待进一步研究;(3)随着时间的推移,产流产沙有所下降,小区坡面的干扰得到了恢复,因此,时间是公路边坡水土流失的重要影响因素;(4)公路边坡的年侵蚀模数,包括降雨侵蚀和冻融侵蚀,共计11991.41 t/km2,属于极强度侵蚀。
    There is extremely fragile ecosystem in the Tibetan Plateau in China because of its severely natural conditions. Once destroyed, it is very hard to get recovered. Especially it is main headwaters for famous rivers such as the Yangtze River, the Yellow River, etc. However, in recent years, China government has been conducting great road construction in the area. These road constructions would cause erosion more and more serious, and sediment from road would destroy aquatic ecology. Now it is necessary to find road erosion principles so as to take scientific and effective measures to reduce or control road erosion adverse effects on aquatic ecology, so we took two years to observe by setting up natural runoff plots on road sideslope (fill slope) of Qinghai-Tibet highway. When each rain was over, we sampled and attained runoff depth and soil loss. Siphonal Automated Record Rain Gauge recorded the rainfall process. After analyzing these data, we get the following results: (1) The product of rainfall and average rainfall intensity (PI) is well correlated to both runoff depth and sediment yield per rainfall event. In addition, the correlation coefficient between runoff depth and sediment yield per event also can get to 0.771. (2) Runoff depth and sediment yield decrease as slope length increases. (3) Runoff and sediment decrease over time, and the disturbance to plots got recovered during the past two years, so time is a very important factor to affect road erosion. (4) According to the existing datasets, soil losses of road sideslope is 119.91 t /(ha穉), including rainfall erosion and freezing and thawing erosion. The results of this study show us that the idea of USLE (Universal Soil Loss Equation) in America can be used for road erosion prediction after revised under specific conditions. Overall, this study explored the factors influencing road erosion and how they affect, so it is significant not only to make road erosion prediction model, but also to protect environment especially for watershed ecology.

    文章以详细的1981年土壤分区资料为基础,将以发生分类(GSCC)为基础的土壤类型名称分别参比成中国土壤系统分类(CST)名称和美国土壤系统分类(ST)名称。同时利用GIS空间分析技术,确定了中国8个土壤大区在地级市(盟)和各县、区、旗(市)的行政归属,并以江南低山丘陵和台湾北部地区为例,探讨了二级分区的行政归属。
    In the past, soil type names involved in soil regionalization programs in China were those adopted by internationally unknown and imcomparable Genetic Soil Classification of China (GSCC) system. Consequently, both soil names and soil regions concerned in such regionalization programs were not good for scientific exchange and comparison in the world, even in China itself. Besides, lack of adequate correlation between soil regions delineated in such regionalization programs and administrative zones resulted in difficulties for application of soil profile data and soil region data. In this paper, soil names adopted in GSCC are converted into those adopted in Chinese Soil Taxonomy (CST) and US Soil Taxonomy (ST) respectively on the basis of detail soil region data in 1981 regionalization program and soil name reference system. At the same time, with the aid of GIS, the correlation between 8 great soil regions in 1981 regionalization program and their corresponding administrative areas at both prefecture and county levels are determined, and for more detail case study, the correlation between the soil region of low-mountain-hilly south of the Changjiang River as well as northern Taiwan in the same program and their corresponding administrative areas is also discussed.

    文章对比分析了植被和沉积物中N、P垂向分布和季节变化,探讨不同植被对潮滩湿地N、P动态变化的影响。分析表明:潮滩湿地的分带性差异使N、P在潮滩湿地各地带有不同的分布规律和季节性变化特性,植被尤其是有较高地下生物量的互花米草和芦苇在整个潮滩湿地N、P的分布以及季节变化中起重要作用,潮滩植被主要是通过N、P在体内的主动转移,植物对沉积物中N、P的吸收以及富集死亡的地下根茎中分解矿化后释放的N、P来影响沉积物中N、P分布的; 1~4月通过枯落生物量回归到地面的N、P总量分别达到149.4 t和18.2 t,对整个湿地生态系统的生源物质循环以及生态环境产生很大影响。
    In this paper, the biomass of different plants in winter and spring are estimated. The contents and variations of N and P of plants, surface layer and core sediments in different ecological zones are also compared and analysized. Subsequently, the dynamic variations of N and P, which influenced by absorption, accumulation and transformation of different plants, are discussed. The results indicate that: for the zonation of tidal flat and different physiology construction of plants, the N and P show different distribution patterns and seasonal variations in different ecological zones; plants, especially perennial Spartina anglica and Phragmites communis with high ratio of aboveground and belowground biomass, play more important role in contents and seasonal variations of N and P in the whole tidal flat sediments; the main mechanism that the plant influence the sediment content of N and P include the active transformation of N and P in plant body, the absorption effect of plant, and the release of N and P from the decomposed and mineralized deceased belowground rhizome that accumulated in the belowground sediments; the quantities of N and P, returning to the ground with withering in different ecologic zones, reach 149.4 t and 18.2 t from January to April, and the biogeochemistry cycle and ecological environment of the tidal flat can be seriously affected.

    Following the development of Industrial Ecology (IE)and the widespread promotion of Circular Economy (CE), Eco-industrial Parks(EIPs)have been rapidly developed throughout the world and become a new industrial paradigm of 2lth century. An EIP is a district where enterprises are organized according to industrial symbiosis and Circular Economy. It aims to optimize the integrated benefits of environment, economics and society in the park. With the exchange of all kinds of flows including materials,energy and information etc., eco-industrial park forms a mutually beneficial network. Through the infrastructure and information share, members of EIP can realize energy cascading and material recycle. EIP is considered to be an important approach to sustainable development. Nowadays, EIP is undergoing a fast development in many countries. In China EIP has rapidly been developed since the late 1990s. Up to the present 15 national EIPs have been approved and about 100 EIPs on local levels have been planned or built. It is important for China to research on the practices of EIP and use the experiences of successful cases for reference, which makes great significance to the development of EIP and regional economy. The development models embody the features and differences of EIPs in some measures. Basing on summarizing and classifying the types of EIPs, analyzing and comparing the advantages and disadvantages of typical EIPs, and then combining the conclusions with the practice of EIPs in China, this paper gives some references to the diverse development of EIPs in the whole country and choices of appropriate development models of EIPs in different regions.

    This paper makes a fractal study on hierarchical structure of tourist scenic spot system in Nanjing, in that, the author has put forward the basic methods of Fractal Geometry and Fractal Informatics to study the hierarchical structure of these multi-level complicated systems. The authors make the values of all scenic spots on the tourist attraction in the scenic spot system as a discrete set , and analyses the character of distributing change on hierarchical structure of tourist scenic spot system by calculating the value of information fractal dimension, and reseaches the distributing model on hierarchical structure by calculating the value of Zipf dimension of it. According as the National Standard, the author makes the hierarchical evaluation to tourist scenic spot. The tourist scenic spot system is in chaos, and their evolutive tendency is some kind of strange attractor which behaves non-integer dimension and infinite nested self-similarity structure, so that it is optimal choose for applying the fractal methods to study structure of tourist attractions systems. The fractals behaves non-scaling and self-organization with natural optimized structure. And because the fractals behaves non-scaling, some kinds of fractal dimensions are characteristic parameters to measure the fractal. Tourist scenic spot systemy structure are in possession of fractal character, so that it is feasible that the authors apply the fractal methods to studing the structure of tourist scenic spot system. The author divides the tourist scenic spots systems of Nanjing into three sub-systems by judging their tourist contact and their administrative subjection, known as the north system, the south system and the middle system. On the base of the hierarchical evaluation to tourist scenic spots, the author has measured the value of fractal dimension of each tourist scenic spot system, and has draw out charts of fractal dimension of the hierarchical structure of tourist scenic spot system in Nanjing, and has them analyzed and compared. Then, the authors have educed that the hierarchical structure of tourist scenic spot system in Nanjing has behaved obvious fractal character, moreover, the hierarchical structure has showed a self-organization optimized evolutive tendency, but there is difference among tourist scenic spot system. Finally, the author has given some primary advices of adjusting the hierarchical structure.
