基于水资源的水量、水质、水域、水流四要素，对区域水资源承载能力概念进行界定；根据水资源承载力主客体定义，从水资源、社会经济、生态环境三大系统分析水资源承载力影响因素，建立了水资源承载力影响因素基础集；构建由目标层、要素层、表征层及指标层构成的多层次、分要素、能力-负荷双向表征的水资源承载力诊断指标体系，并从量、质、域、流四要素识别了水资源承载能力关键诊断因子。
Abstract
Based on the basic factors of water resources, including water quantity and quality, the connotations and functions of water resources are further expanded for the multivariate system of water resources carrying capacity and the concept of carrying capacity is proposed from the quantity，quality，space and flow of water resources. According to the subject and object of water resources carrying capacity，a fundamental set of influence factor is structured from water resources，social economy and ecological environment system. The diagnostic system of water resources carrying capacity is composed of the target，the elements，the representations and the index，which is multi-level，multi-element and bi-directional characterization between capacity and load，and the key diagnostic factors are determined from the quantity，quality，space and flow of water resources carrying capacity by the entropy weight method and the DEMATEL.
