| 摘 要： | 通过南京市六合区降水量的统计分析,验证了六合区年降水量近似服从正态分布,雨量年内分布极不均匀,5～9月降水量占多年平均年降水量的64.8%,年雨量从1980年以后呈明显的上升趋势,发生大雨、暴雨的年均次数均有所增加.六合区降水量地区分布特性显著,即雨量分布从南向北逐步递减.

| Abstract: | Based on the statistical analysis of precipitation of Luhe rain-gauge station,the distribution of the normal distribution pattern of the precipitation of Luhe District in Nanjing City has been proved.The annual precipitation of Luhe District is quite nonuniform with the rainfall from May to September of 64.8% of the mean annual precipitation therein,and the annual precipitation has an obvious uptrend since 1980 along with the somewhat increase of the annual times of downpour and rainstorm.The distribution f... |
