摘要
通过对唐山水文站短历时暴雨资料分析计算，采用皮尔逊Ⅲ型分布和耿贝尔（Gunlbel）分布对该站不同历时的暴雨强度分布进行了适应性分析，并利用SPSS软件的非线性回归计算，求得两种分布的唐山市区暴雨强度总公式和暴雨强度分公式，并对两种分布的计算误差进行了简单分析，为唐山市城市防洪规划和排水设计提供参考依据。
Through analysis and calculation of the short duration rainstorm data of Tangsban Hydrometrie Station, we made an adaptive analysis on different durations of rainstorm intensity distribution in this station by using Pearson-Ill distribution and Gumbel （the Gumbel） distribution, obtained the general formula and sub-for- mula of rainstorm intensity in two distribution of Tangshan City by using SPSS software, and analyzed simply the calculation error of two distribution, which can provide a reference for urban flood control planning and urban drainage design basis of Tangshan
