本文首先明确了水资源承载力的基本概念 ,指出可持续发展理论、水 -生态 -社会经济复合系统理论、二元模式下的水文循环机制和过程是水资源承载力研究的理论基础 ,对水资源承载力研究的基本内容、评价指标体系的建立和评价方法进行了较全面的概括和总结。

As a principle index to measure water resources security, water resources carrying capacity relates with the problem of water resources security closely and becomes an emphases of water resources study which has important effection on the recognization and construction of water resources security system. Based on the definition of water resources carring capacity, this paper brings forward the theories about the study of water resources carrying capacity, concerning with the sustainable development, water resources-socialeconomy-environment coupling system and water cycle in duality mode. After a overall review of the contents and evaluation index system, the paper summarizes the evalauation methods of water resources carrying capacity study, including the imitate model with system dynamics theory, the decision model of multiple-purpose planning etc.. Finally, the paper points out that the further study of water resources carrying capacity should strengthen integration study of different subject, apply the new technology of GIS and RS actively and pay more attention to the study of region diversity.
