摘要
以江西省和福建省的86个水文站的年最大洪水资料为样本,在成因水文分区———模糊聚类法的基础上,采用线性矩区域综合方法进行区域洪水频率分析,并选用两种区域洪水分布线型:通用极值分布(GEV)、P-III型分布来检验这两省的洪水特性。结果表明,P-III型分布优于GEV分布。
The annual maximum flood data from86stations in Jiangxi Province and Fujian Province was applied as samples for regional flood frequency analysis using the L -moment estimation method based on genetic classification-- - fuzzy cluster analysis.Generalized Extreme-value distribution(GEV)and P-III distribution were selected to test flood characteristics of two provinces.The results show that using P-III distribution to estimate floods is more feasible than using GEV distribution.
