利用中国气象中心160站点的夏季降水实际观察资料,对中国半个世纪的降水变化按年代进行了系统分析,并对各地的代际降水量变化趋势进行了区域对比.结果发现,降水变化幅度大的区域主要集中在季风区.而非季风区的年代际降水相对稳定.在多数情况下,以四川为中心的区域的降水量变化与东北的北部一致,东南沿海与渤海湾沿岸区域一致.季风区降水量变化的区域差异,可能既受季风的年代际强弱变化的影响,又受微地形的影响.

The summer precipitation variation series of 160 stations were analyzed to find the decadal and spatial precipitation varia-tion across China during 1951-2002. Results showed that the precipitation in the monsoon covered area has larger variation ampli-tude. On most occasions, the precipitation in the Sichuang centered area has a similar variation trend with that of the north part of Northwest China, while the precipitation in the area around Pohai Sea has similar trend with that of the costal areas of Southeast China. The precipitation variation in the monsoon covered area is due to the strongness of the mosoon as well as the effects of land-forms.
