| 中文摘要: |
| 边缘分布选择正态分布、对数正态、指数、威布尔、最大极值、最小极值和伽马分布，采用二维Gumbel-Hougaard Copula函数研究最大1日降雨量、最大15日降雨量与河流洪峰流量的关系.以小清河黄台桥水文站23年数据为例进行计算，结果表明，最大15日降雨量与洪峰流量相关较好.本研究为降雨和洪峰流量关系研究提供了有效的途径. |
| 英文摘要: |
| The marginal distributions used were：normal，lognormal，exponential，weibull，max，min and gamma distribution.Gumbel-Hougaard Copula was used to study the relationship among 1day max rainfall，15 days max rainfall and river flow.23 years data of Xiaoqing river in Jinan Huangtaiqiao hydrological station was taken as example.The research shows that the relationship between 15days max rainfall and river flow is better. |
