| 摘 要： | 本文较为详细地分析了1961-2000年汛期5～9月江苏省四大流域面雨量年际、月际变化特征及面雨量的空间分布特征，提出了面雨量异常指数的定义，进行了极值分析，并分析了1980-2000年江苏省内涝对应的面雨量极值、面雨量距平。统计结果表明，强降水面雨量能较好的表征洪涝程度，为今后进一步研究流域面雨量致灾预测打下了基础。

| Abstract: | On the basis of the data of the main four valleys'area precipitation in Jiangsu Province,May to September,1961 to 2000,the article analyses its interannual and intermonthly change and dimensional distribution, defines the abnormal index of valley's area precipitation,and discusses its extremum,then studies the relation between the waterloggings and the extremum and departure of the valley's area precipitation from 1980 to 2000 in Jiangsu Province.The research shows that the valley's area precipitation of heavy rainfall can represent the degree of waterlogging quite well.And the result supplies a good basis for the further study on the prediction of the disasters resulted from valley's area precipitation of heavy rainfall. |
