| 摘 要： | 在未来的亚洲中中气候变冷过程中，从咸海干涸海底和卡拉博加戈尔湾等等内陆湖泊和地区吹起的盐粒，农田排出的农药残余物，尘埃微粒等－固态大陆型气溶胶具有主要的作用。在这一过程中，环流及该区域的生物系统对气候的变化可能起着相反的影响。

| Abstract: | Climate is a very complex natural system. To Know the trends of climate changes, it is necessary not only to study systematically some key factors such as those of astronomy,geophysics, atmospheric circulation and man-made factors, etc-, which can produce effects on climate, but also to analyze modern regional environmental features carefully.Salts blowing up from the dried bed of Aral Sea (since 1968), in1and lakes (such as Karabojazer Bay) and deserts, survivals of pesticides of the cropland and dust particlescontinental solid aerosols will play a very important role in process of cooling of future climate in Central Asia. The ocean circulation (in Pacific) and the eco-system in Central Asia will have a counter influence on local climate.In this paper, the features of the spatial and temporal distribution of surface water resources in north Xinjiang are analyzed by using an empirical orthogonal function expansion. on basis of the researches done before, the sequence of surface water resources in north Xinjiang is extended from 200 to 412 years, under the satisfactory conditions for combining two different sequences of tree-ring chronogies into one sequence. Considering the regional characteristics of water resourecs circulation, the water resources in the south Xinjiang is analyzed by using historical data. The above research resuIt show that the cooling trend of climate in Central Asia will produce some good effects on water resources in Xinjiang. |
