| Abstract: | In this paper,the concept of generalized water environment carrying capacity(WECC) and its corresponding assessment index are put forward based on the analysis of generalized water environment system.The set pair analysis(SPA) method for regional WECC assessment is improved through introducing the entropy weight method.Taking Guangdong province as a case,the assessment indicator system is estabished according to the practical situation of water environment in Guangdong Province.The regional WECC in Guangdong province and its three sub-systems are comprehensively appraised by adopting the improved SPA method.Finally,the improved measures of regional WECC are presented. |

| Keywords: | generalized water environment carrying capacity set pair analysis improved entropy method index system |
