    从本世纪30年代陈国达提出"丹霞地形”的概念以来,中国学者经历了初创、成型和发展三个阶段的研究,作为地貌学一个新领域的丹霞地貌研究已日趋成熟."红色陆相碎屑岩”作为丹霞地貌的物质基础和"陡崖坡”作为形态限定为大部分学者所接受."顶平、身陡、麓缓”的坡面组合,是丹霞地貌的基本形态特征.目前所发现的红层均不早于中生代;大部分丹霞地貌发育在红色砾岩、砂砾岩、砂岩的地层组合上,而相对软弱的粉沙质和泥质岩多发育红层丘陵.丹霞地貌发育的构造基础表现在区域构造控制沉积盆地;盆地内部构造控制丹霞山块格局乃至山块形态;岩层产状对丹霞地貌形态的影响主要是对于山块顶面和构造坡面的控制;而地壳升降则控制地貌发育的进程.直接影响丹霞地貌发育的外动力主要有流水、风化、和重力等作用,其中流水是塑造丹霞地貌的主动力;流水侵蚀和风化提供了重力崩塌的条件,而丹霞陡崖坡则往往是崩塌面或经后期改造的崩塌面.在干旱区,风力侵蚀和盐风化对于丹霞地貌外表形态塑造具有不可忽视的作用;在湿润区,生物对风化作用有一定影响.丹霞地貌区往往是生态相对比较脆弱的地区,但却风景优美,文化景观丰富,大多具有较好的旅游开发价值.
    Danxia landform belongs to red terrestrial elastic rock landform, which is characterized by its red cliffed scarp. The development of Danxia land form research in China experienced three history stages, i. e.; Prof. Guoda Chen raised initial establishment and taking shape and expanding since the concept "Danxia landform" in 1939. As a new branch of geomorphology, Danxia land form research is now stepping its ripe stage. In 90’ s, their search enters into an unprecedented grand occasion at the prompting of tourism exploit. Danxia landform is classified into rock land form system. That the red terrestrial elastic rock being its material base and that steep scarp being its type form are accepted by most of researcher in this field. The constitution of leveled-top and cliffed-scarp and gentle-fool is the type shape of Danxia landform. In different area, the provincial characteristics of Danxia landform are different from each other due to their geography environment differences. Danxia land form developed only when the Earth crust reached its specified development stage, e. g., all red beds found on the Earth are not earlier than Mesozoic era. Most of Danxia landforin formed on red conglomerate rock, sand-conglomerate rock and sandstone. Meanwhile, red bed hills formed on siltstone and mud stone due to their flexible texture. The regional tectonic pattern, which controlled the distribution of sedimentary basins, is the tectonic base of Danxia landform. Tectonic lines within the basin controlled the distribution pattern and even the shape pattern of Danxia landform mountains. Supper surface of a mountain and tectonic dome of Danxia landform were controlled by the rock occurrences. Crystal movement controlled the development of Danxia landform. Exogenetic forces influenced the Danxia landform development included alleviation and weathering and gravitation processes, among which the alleviation process is the main force formed the Danxia landform. Alluvial corrosion and weathering created favorable condition for the gravitational eboulement, Danxia landform cliffed scarp is often the eboulement surface or reformed one. Wind erosion and saline weathering are unponderable forces in forming Danxia landform in arid zone. Organism activity is advantageous to weathering in humid zone. Artificial Danxia land form landscape is the product of exploiting stone. Danxia landform often distributed in weak ecology system areas; however, its tourism development value is often high due to its beautiful landscape and plentiful cultural scenery. The Danxia landforin research is aim at its development principles, taxonomy, landscape quality evaluation and graduation, natural mountains and river culture and human culture scenery, nature resource protection and utilization, and etc. All of which are beneficial to regional economic construction. In recently years, symposium of Danxia land form landscape resource and its tourism development are very active, which make a great contribution to regional tourism development.

    京津地区近50年来水稻播种面积变化及其对降水变化的响应研究
    苏桂武, 方修琦
    地理科学. 2000, 20 (3): 212-217.   DOI: 10.13249/j.cnki.sgs.2000.03.212
    摘要   PDF (508KB)
    基于滑动-t突变检验结果,对京津两地近50年来水稻种植面积的变化进行了阶段划分,并分别讨论了各阶段的变化特点.两地水稻种植面积的阶段性变化均受自然、技术和政策等多方面因素的综合影响.事件相关分析发现,作为人类对降水变化响应的水稻种植面积的变化较降水变化滞后一年,使得年雨量变化与当年水稻种植面积变化之间存在明显的负相关.
    According to the result of Moving-t test analysis, The changes of rice-seeded area during the past 50 years are divided into three stages, 1949-1968, 1969-1985 and 1986-1996, in Beijing, and two stages, 1949-1971 and 1972-1995, in Tianjin, respectively. In both regions, the rice-seeded areas show the fluctuation from rise first and then fall down. And before 1970, the changes in the two regions were, on the whole, similar. But after 1970, the changes in the two regions tended to difference. The changes of rice-seeded area in both regions were all resulted from the comprehensive influence of the natural, the technological and the political factors. It is the faultiness of the policies that has made the rice-seeded area being extended over the capability of water resource supply. In order to serve the need of the rice planting, the exploitations of water resources in both regions all have been extended from rain to surface water and then to groundwater. But when the water resources still could not meet the need, the rice-seeded area was reduced. As a response of farmers to the annual rain variation, the variation of rice-seeded area is lagged behind that of the rain by one year, which resulted in the remarkable negative correlation features between the precipitation of a year and the rice-seeded area of the same year. Such important phenomena makes the water resources can not be used sufficiently in the years with more precipitation, but the shortage of water resources be strengthened in the drought years.

    The exploitative intensity of land resources in Yangtze River Delta region has been discussed in this paper. Through interpretation in terms of theory and quantitative evaluation, the implication of land exploitative intensity is stated clearly, and relative measurement method is put forward. "High intensity exploitation of land resources" is defined scientifically. It shows that land exploitative intensity grade in Yangtze River delta is high intensity in country, and that its grade is low intensity in the world. The authors put forward the ways to deal with land high intensity exploitation in the Delta, such as the improvement of exploitative technology and human environment, the strengthening of exploitative intensity of low-grade units in the region, and the exploitation of water and land resources by sticking to principles of integration, high efficiency and lastingness. In the same time, the authors emphasize that utilization and protection are both important.

    As one of the key issues of regional respond to global climatic change, the sustainability of agricultural production under the changing climate is attracting more and more academic focuses. The impact of climate change on the agriculture results from the change of climate elements mean values and of the climate variability. The assessment system of winter wheat water and yield in the Huang-Huai-Hai Plain, the main production area of food in China, is submitted in this paper to discuss the impact of climate variability and future climate on the production of wheat. The system is made up with a set of models, which is based on the following idea. Crop uses water in the form of the transference of precipitation, soil moisture and plant water. The situation of crop water supply and requirement can be expressed by the relationship between actual evaportranspiration and potential evaportranspiration. Then we can estimate crop yield from the loss of evaportranspiration. The simulation of water balance during the growth period of winter wheat shows that the deficience of water are 200400 mm in the area of north of the Yellow River, 100 mm or so in the middle part of the Plain, and nearly zero in the area including south of Henan province, north of Anhui and Jiangsu province. The spatial divergence of irrigation amount is discussed, too. From the water balance estimation model, the yield of winter wheat can be calculated under the scenario of climate change in the future. So the change of yield of winter wheat in the Plain in the future is given, which is yield decrease in the most part of the plain.

    In view of change of entropy in ecosystem, this paper focuses on elaborating the method of comprehensive evaluation and rational regulation to eco-environment of oasis, which meet the demands of factorial quantification and suit the integrated evaluation of natural-economic-social attribute, soas to lay the foundation of restoration and rehabilitation of eec-environment of oasis. According to dissipative structure theory advanced by Prof. Prigogine, entropy and change of entropy in ecosystem can be defined as S=Q/P, and △S=S2-S1-S12, where S stands for entropy of ecosystem, Q stands for energy output (or input), P stands for economic income (or expenses), S1 stands for primary entropy of ecosystem, S2 stands for final entropy of ecosystem, S12 stands for intermediate entropy of ecosystem, that is, it is also negative entropy flow which ecosystem in a motion state get from external environment, and △S stands for change of entropy in ecosystem in a motion state. Supposition the total of change of entropy in ecosystem △S= 0, and Y=S12, namely Y= S2-S1, where Y is entropy production of inside of ecosystem or stability of ecosystem, which can be used to describe good or bad about structure and function of ecosystem. With case of Wuwei City, Gansu Province, based on the principle of stability, simple, integrity and territory, percentage of forest coverage (x1), the proportion of cultivate grass area in cultivated area (x2), desertified land area (x3), soil erosion area (x4), the proportion of ensured irrigated area in cultivated area (x5) and depression depth of ground water table (x6) can be chosen as independent variable, and stability index of ecosystem (y) as dependent variable, a multivariate nonlinear regression equation is given by the applied of stepwise regression analysis. Thus, the evaluation for ecosystem of oasis should focused on the change of entropy in ecosystem △S and stability of ecosystem Y, and the regulation for one could obtained from the solution of ∂y/∂x1 =0. The results of comprehensive evaluation for ecological environment of oasis are given as follows: 18 village (town) are classified Ⅱ, 15 village (town) Ⅲ and 5 village (town) Ⅳ, and entropy values of stability of ecosystem are 26.14-29.06×106, 29.43-34. 92×106 and 37. 32-47. 13×106 calorie/yuan (RMB) respectively. On the basis of the contribution or weight of each evaluating factor to stability of ecosystem of oasis, some managagerial strategy for ecological environment of oasis such as reverse of desertified land, strengthening conservation of water and soil, rehabilitation of shelter forest system, increasing cultivate grass area, control depression range of ground water table and stabilization ensured irrigated area are put forward.

    对临夏盆地1Ma以来地层中的石英砂所作的扫描电镜分析表明,风成砂一直存在,并在8Ma和6~Ma时含量最高.最大颗粒的平均粒径在(1.5~3.6)/2.6Ma达0.4mm,3.6~2.6Ma之后显著下降.前者表明3.6~2.6Ma以前,近源风沙作用一直存在,并在8Ma和6~Ma达到最盛;后者表明第四纪以来,远源风沙沉积盛行,可能反映了青藏高原在3.6~2.6Ma急剧隆起和与之相关的大气环流的改变.
    Atotal of 55 samples were taken from the Tertiary red earth and Quaternary lacustrine deposits and loess for Linxia Basin for the analysis of quartz type and content using electron probe microanalyzer. The eolian sand contents appeared two high values at about 8Ma and 6-5Ma respectively. The mean size of quartz grains was about 0.4mm during the 15-3. 6/2. 6 Ma period and dropped down to 0.1mm dramatically after 3. 6-2. 6Ma. These results mean the eolian deposition reached its maximum at 8 Ma and 6-5 Ma respectively. Since the Quaternary, the local eolian deposition was decreased significantly and disappeared which was replace by dust deception from far source, suggesting the uplift of Qinghai-Xizang Plateau and the change of air circulation.

    El Niйo and La Niйa are the phenomena concerned internationally. The author refers to all scientific research achievements at home and abroad, describes their basic notions and features, analyses and discusses several typical formative principles. Finally he concludes that the appearrance of El Niйo and La Niйa results from the unbalance of the air stream interaction on the sea no matter what kind of processes they are. Both El Niйo and in Niйa are not isolated, so they make global and peculiar influence on the climate even if they only appear on the 1/4 tropical sea surfaces. El Niйo mainly affects the distribution of drought and flood at a large scale, i. e. the flood on the east of the southern Pacific Ocean and the drought on the west of the Pacific Ocean and Africa. On the other hand, La Niйa disturbs the usual climate features of one area, i. e. originally there ought to be plenty of rain fall in a certain season or area, but now it is especially hot. Furthermore, it can deteriorate the climate feature, making the dry area drier and the wet place wetter. In the end, the article comments on the influnce of El Niйo and La Niйa on the climate of our country, analyses the existing problems at the present academic field and points out the prospects of our future work.

    莫莫格湖泊群水位和生态环境的变化,主要取决于大气降水和河流水位的变化.近50年来,湖区气温逐渐上升,在自然因素和人为活动的影响下,湖泊水位有逐渐下降的趋势,湖泊生态环境不断恶化.
    The Melmeg Lake groups are located on the right side of backward position of the Nenjiang River. Here is lower physical features, lake, marsh and wetland are linked, the aquatic plants are flourishing, here provides an ideal house for birds. e. g. red-crowned crane. The lake-level change and eco-environment change are mainly decided by the change of rainfall and river-level of fifty years. There is a tendency to warm up in climate of Songnen Lake region in fifty years, the fluctuation range of water-level gets bigger, the eco-environment becomes fragile. The human activities e. g. water conservancy facilities, agricultural cultivation and industrial pollution give rise to lake groups and their environment change which include positive and negative sides. Although the intensity differs from the space and time, yet the overall tendency is that lake-level drops and ecological environment gets worse.

    江苏沿江地区的空间结构是距上海市距离和到最近长江港口距离2个因素综合作用的结果,据此可由江苏沿江地区人均GDP的分布状态而反推出上海市市区的人均GDP值.近10多年来该地区的长江南侧形成了一条新的发展轴线,表明苏南的区域空间结构已基本成型.就港口与区域的关系而言,该地区的长江南北两侧,均遵循港口与区域互动的协调发展模式.这一发展规律的揭示,对轴线尚未成型的江北区域的发展,具有重要的指导意义.在此基础上,本文探讨了宁合芜与江张靖两个成长三角的构建.
    The spatial structure of the region along the Yangtze River in Jiangsu province is the result which is acted synthetically by the distance from Shanghai and from the nearest port of the Yangtze River. Based on this, the GDPPC of Shanghai City can be deduced by distributing status of GDPPC of the region along the Yangtze River in Jiangsu Province. In the recent ten years, the south side of the Yangtze River of this region has formed a new developing axes. It makes clear that the regional spatial structure has basically formed. To the relationship of port and region, both sides of the region along the Yangtze river follow the mutual unisonous developing pattern which port and region motivate each other. This law can instruct the development of the region along the Yangytze in north part of Jiangsu province, whose axes hasn’t formed. Based on this, the article studies the building of two developing Triangles of Nanjing-Hefei-Wuhu and Jiangying-Zhangjiagang-Jingjiang.

    《中国沼泽志》的出版发行是我国沼泽湿地研究的重大事件,是对沼泽科学研究的重大贡献,我热烈祝贺中国第一部沼泽志问世。湿地兼有水、陆特性,具有多种功能、生物多样性丰富,是地球上最重要的生态系统和人类最宝贵的生存环境之一。沼泽是湿地的基本组分,主要类型或核心部分。它同时包揽了湿地的三个基本要素。与其它湿地相比,沼泽湿地更具有代表性和典型性。
