| 摘 要： | 基于有关水文气象测站的观测资料,对全球变暖背景下新疆降水的时空分布特征、演变趋势与变化原因进行了分析。结果表明:近40年来新疆年降水量总体上呈增加的趋势,并且不同地区降水的区域性差异十分明显。从年代际变化来看,新疆降水从上世纪60年代到80年代中期处于振荡减少阶段,80年中后期以后降水呈振荡增加趋势,且1987年为一个降水突变的拐点;新疆年平均降水量的增加主要应归因于全球变暖所带来的境外输入水汽量的增加。

| Abstract: | The spatial-temporal distribution,evolvement trend and change causes of precipitation in Xinjiang Region were analyzed based on correlative observation data at 62 weather stations and hydrometric stations.The results show the yearly mean precipitation in the Xinjiang was presenting the increasing trend in recent 40a,and the regional differences on precipitation in various areas of the region were quite obvious.It could be distinctly discovered looking back the decades evolvement process of the precipitation in Xinjiang: the precipitation in the region showed step by step decreasing phase during the period from 1960s to mid of 1980s and again increased step by step after mid of 1980s.1987 was an inflexion of precipitation variation in the Xinjiang.The increase of precipitation in the region principally was resulted from Global warming. |
