摘要
天山东段哈密庙儿沟、乌鲁木齐河源冰川;中段卡拉格玉格冰川和阿克希拉克山地冰川;西段图尤克苏冰川及其他冰川,本世纪40年代起一直处于退缩状态(较少冰川例外)。冰川物质平衡观察显示出80年代比以前突出的亏损。反映了中亚天山地区气候干暖趋势增强。应用新疆气候、水文和树木年轮研究成果综合分析,预测2000年新疆天山地区气候将出现降水偏多、气温维持平均值或略有下降的趋势。
A great number of glaciers in the Tianshan Mountains have always been in the state of retreating ever since the 1940's. Large deficit of mass balance has also been observed during the same period, especially during the 1980's. The retreat of glaciers and deficit of mass balance show an enhanced tendency of climate towards dry and warm in the area of the Tianshan Mountains. By incorporating the results of climate, hydrolohg, and tree—ring studies in Xinjiang. It can be concluded that the air temperature in the area of the Tianshan Mountasins will remain close to or decrease slightly below the average, and the precipitation will show a increasing tendency after the year of 2000.
