摘　　要：通过长系列降雨资料统计,计算多年平均降水量,分析降水量实测资料系列长、短对所求得的平均年降水量的影响。用各分区逐年降水量系列进行频率分析计算,求得不同频率的年降水量。利用最大年降水量与最小年降水量比值来分析降水量的年际变化特征。Through calculation of annual precipitation according to the statistical data based on long-series of precipitation data, the influences of length of data series on the calculated precipitation were analyzed. Precipitation under different frequencies was calculated according to frequencies computation based on a series of annual precipitation data in different districts. The inter-annual change of precipitation was analyzed through the ratio of maximum and minimum precipitation.
