    The Chinese precipitation patterns in flood season associated with the ElÑino/southern Oscillation(ENSO) are investigated, especially in the eastern China, using the rather long period rainfall data in this century. The results show that there are remarkable differences between the precipitation patterns in ENSO warm phase (ElÑino year) and cold phase (LaÑino year) flood seasons, as well as between the patterns in ElÑino years and their next years. The most parts of China receive below normal rainfall in ElÑino year flood seasons, but the coastal area of Southeast China receives above normal amounts. Comparatively, the most parts of China receives above normal rainfall in ElÑino’s next year flood seasons, but the eastern part of the reaches among the Huanghe (Yellow) River, the Huaihe River and the Haihe River, and theÑortheast China receive less. During ENSO cold phase, the reaches of the Changjiang(Yangtze) River and theÑorth China receive more amounts than normal rainfall in LaÑino year flood seasons, and the other regions of China receive less. In LaÑino next years, the coastal area of the Southeast China, the most part of theÑortheast China and the regions between the Huanghe River and the Huaihe River receive more precipitation during flood seasons, but the other parts receive below normal precipitation.

    According to the field expedition and statistical data, there are 437 glaciers, covering the total area of 1552. 39 km2 with the ice storage of 162. 8349 km3 in the Hoh Xil re-gion, Qinghai Province, being important water supply sources to the river and lakes in the region. Development of glaciers in this region is clearly affected by the climatic and topo-graphical conditions. Statistical data show that 61.8% of the total glacial number and 85. 5% of the total glacial area with 91. 4% of the total ice storage concentrates in the high mountain areas 6 000 m a. s. 1.. The equilibrium line elevation (ELE) of glaciers is de-creasing with the latitude increasing, average lowering 125m/1. Otherwise, the ELE in-creases from the east to the west in each mountain range, which is coincident with the de-crease in precipitation from east to west, reflecting the vapour in the air coming from the southwest monsoon through the path of southeastern Xizang (Tibet). Besides the precipi-tation caused by the monsoon transporting vapour, the precipitation caused by the local circulation is quite important supply source to the glacial development in the interior mountains. The geomorphological feature of the lake basins alternating with the mountain ranges in the Hoh Xil region is of benefit to the local circulation. In recent period, all of glaciers are retreating with the climate warming.

    The paper attempts to examine the relationships between industrial organizations and their environment from an essentially spatial perspective and organization theory, and inte-grate the generalizations derrived from organization theory and industrial geography to i-dentify spatial linkage patterns created by the enterprises, both in the aggregate and indi-viduallly. These issues are organized around three elements. First, we attempt to examine the conceptualization of spatial linkages of enterprises. Second, we identify the patterns of enterprises under different economic systems and its features in China. Third, particular attention is then given to the relationships between three aspects of organizational struc-tures and its external environment, and its spatial linkage patterns of enterprises. From many organizational factors which might influence the spatial linkage patterns, five have been selected for analysis. They are product types, type of enterprises’ownership (that is, whether or not it is under external control), size of the enterprise, operational technology and organizational complexity. These factors was by themselves highly correlated with value or volume of material and market linkages. Finally, we analyses the changes of spa-tial linkage patterns over time, of a representive sample of the Nanjing Automotive Indus-trial Corporation, and illustrates the the findings with case studies.

    Based on the prediction of GCMS, by the middle of the next century, the concentration of CO2 in atmosphere will be doubled and the global temperature will increases about 2℃, vegetation response to global warming,in Northeast China will be the followings:1. The future alternate types of edificators can be divided three types (extending population; retreat population; extinct population). 2. The decision of the future distribution border of edificators as climate warming. Based on this formula: WI =288. 94-251X-0.81Y-0. 038H, (R=0.9812), it is calculated that the edificators will move northwards about 400-700 km when the temperature increases 2℃ and the population moves upwards 250-350m. 3. The influence of climate warming on the distribution border of cultivated crops. The northern survival border may move northwards 110-160 km for apple, 220 km for cotton. The elevation for ginseng cultivation will increase to 750-800 m. 4. The influence of climate warming on the growth and development of plant. Based on the function of frost-free period (F) = 3.7945 + 7.4581t, the growth period of plants will pro-long for 15 days and the phenological development of trees will roughly advance one sea-son. 5. The influence of climate warming on productivity. The productivity of main forest ecosystems will increase 7.65% and that of main agroecosystems will increase 36.4%.

    The data of Fe3+/Fe2+ show that the lowest annual air temperature of the Lushan, Huangshan and Tianmu mountains didn’t reach below 0℃ therefore, glacier couldn’t develop in these regions. According to palaeomagnetic test combined with the phenomenon of red reticulate ground and lithologic identification, the author elaborates that the "Poyang moraine" is mainly the fluvial sediments of the early period of the Middle Pleis-tocene. It was formed by transportation of the ancient Gan River under the humid hot cli-mate. For C-M image, the Dajiaochang profile of Lushan Mountain is very similar to periglacial and the debris flow deposits, but the profile of Jiangpochang and Yaoshalin have many kinds of geneses, i. e., debris flow, water debris flow and alluvial etc. In the south piedmont of the Huangshan Mountain, slope gravity and slope seasonal running wa-ter transportation are mainly deposit factors. In the "glacial varve" of the Denglongqiao profile of the Tianmu Mountain, its CaO and Na2O content is lower than the nonglacial carve, the fact shows that it has the features of the violent leaching, weathering and nonglacial action.

    In this paper, we review Liang Qichao’s widespread researches, academic thoughts, successes and failures in relation between human beings and geographical conditions over-all and impartially. We fully approve his research achievements in the areas of anthropo-geography. We think that Liang’s relation between human beings and geographical condi-tions researches have explicitly embodied the relation between human beings and geo-graphical conditions and also demonstrated the scientific geographical materialism and the view of dynamic geographical function. The cause and drawback of Liang’s on relation be-tween human being and geographical conditions researches have been analysed. It is point-ed out that the valuable legacies of Liang’s academic thoughts are fundamental to the en-lightenment of contemporary human geography research.

    Oasis is a huge system constructed by natural and human systems in historical stage. The oasis industrial structure stands for the developing level of the productive force, de-termines the function of oasis system and influences the development of the system finally. By analyzing characteristics of industrial structure of Gaotai oasis in the historical stage and predicting its change by grey model, namely GM (1,1), the author classifies the oasis as three types: primitive stockbreeding oasis (1300-121 a B.C.), traditional farming and stockbreeding oasis (121 a B. C.-A. D. 2 000 a), new type industrial oasis (A. D. 2 000 a--) and points out that industrialization of oasis is its positive trend.
