摘　　要：通过对南京站降水量的统计分析,验证了南京站降水量雨型为P-Ⅲ型分布。随着城市化的进程,人类活动加剧,南京站的降水量和发生大雨、暴雨的年均次数均有增加的趋势,1970年后趋势更加明显。城市降水量的增大及大雨和暴雨次数的增多,出现峰高量大的暴雨洪水机会增加,加剧了南京的防洪压力。Though the statistical analysis of precipitation of Nanjing rain gauging station,the distribution of P-Ⅲpattern of precipitation of Nanjing rain gauging station has been proved.With the process of urbanization and the people's activities,precipitation and annual average degrees of rainstorm of Nanjing rain gauging station have been increasing,and the adding tendency are very distinct after1970.Due to the cause of rainstorm,the opportunities of rainstorm flood are increasing,and the pressure of control flood for Nanjing City is added.
