摘　　要：综述了多变量水文分析计算方法及存在的问题。系统地介绍了Copula函数的基本理论与方法,分析探讨Copula函数在多变量水文计算领域的适用性及优越性。总结了Copula函数应用的关键技术,包括参数估计、拟合检验及类型选择等,并展望了Copula函数的研究应用前景。This paper introduced multivariate hydrological analysis and estimation methods and the existent problems. The basic theory and methodology of copula function was introduced systematically, and its applicability and superiority in multivariate hydrological analysis and estimation were explored. The key technology for applying copula function, such as parameter estimation, goodness of fit and copula function selection, were summarized. Finally, the perspective of applying copula function in multivariate analysis was prospected.
