摘要
天山山系深居亚洲大陆腹地，受中亚自然地理环境的制约，在变性西风气流的影响下，70年代至今山地冰物质平衡负值，伴随着气温的变化而增大。湖泊则是随着山区降水量的增加，其面积渐增。气温与降水的相互作用，使得整个天山山系的水资源总量趋于正常略偏多。预期这种气候趋势将会延续到下世纪初期。
The Tianshan Mountains lie in the inland of Asia Continent. Under the control of geographical environment in Central Asia and the influence of modified west air mass. the massbalance of glaciers in the mountain areas has continously decreased since 1970s. IIowever,the lake level has increased gradually due to the increased precipitation. The interaction betweer temperature and precipitation resulted in a normal or slightly more total amount of water resources in the mountain areas of the Tianshan Mountains. It is estimated that this climatic trends will last to the early stage of next century.
