摘　　要：　通过对安阳市41处雨量站资料的统计,并利用泰森多边形法计算各分区逐年降雨量系列以及多年平均降水量,进行频率利用配线法确定不同频率的年降水量,利用年降水量变差系数CV和最大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。On the basis of data statistics of 41 precipitation stations in Anyang city, the article make use of Taisen polygon method to calculate the precipitation for year after year and average annual precipitation for multiple years in each division and match lines method to determine yearly rainfall of different frequency. It analyzes yearly variation characteristics with the variable coefficient Cv and ratio with maximal and minimal yearly precipitation.
