摘要

中文摘要: 尝试将Copula函数应用于水文水资源系统评价。通过Copula函数建立多元联合分布研究各评价指标、各评价标准的相关关系，进而构建评价模型推求各评价样本的综合评价指标值以及各评价类别对应的综合评价标准值，根据综合评价指标值和综合评价标准值对样本进行分类。湖泊水质富营养化评价实例研究表明，Copula评价法的评价结论合理，具有原理明晰、使用简便的特点。

Abstract

Abstract:Copula assessment method is a innovation way for solving the topic of assessment. Copula function is used to construct joint distribution functions for studying the correlation degree of assessment indexes and the relevance pattern of assessment criteria. Hereby the assessment model is established

both the comprehensive assessment indexes values of samples and the comprehensive assessment criteria values of category are defined. Accordingly

based on the comprehensive assessment criteria values

the comprehensive assessment indexes values are classified

and then the assessment conclusion can be summarized. Case study of eutrophication of lake water quality assessment shows that Copula assessment method is of clear principle

stable performance and reasonable results which provides new ideas for the hydrological assessment.
