多变量水文联合分布方法及Copula函数的应用研究

Review on Methods of Multivariate Hydrological Joint Distribution and Copula Function

简介了水文事件中的多变量联合分布计算方法,系统总结了Copula函数的原理、性质、水文计算中常用的函数类型、参数估计方法及拟合检验方法,探讨了Copula函数在水文方面的应用前景。

This paper introduces the methods of multivariate hydrological joint distribution in hydrological events.Copula function is summarized systematically,including its principle,its properties,its main classifications,methods of parameter estimation and fitting tests.The perspective of applying Copula function in multivariate hydrologic and hydraulic analysis is discussed.It points out that a further study should be promoted in the joint probability distribution of water quantity and water yield.
