摘　　要：综合分析了影响汉江地区水环境承载能力的关键因子,建立了适宜汉江地区的水环境质量评价指标体系,经筛选,共选取了8个指标.采用改进的层次分析法确定了各评价指标体系的指标权重,通过单指标承载度数学模型的建立,在相关指标的基础上得出各评价指标的承载程度,应用加权平均法对汉江地区的逐年水环境承载力进行计算.通过对汉江地区水环境承载力现状及逐年变化分析,找出影响汉江地区水环境承载力的主要因素以及提出提高承载力的措施.The critical effect factors of WECC on the river are analysed in this paper,and the evaluation index system of WECC of the Hanjiang River is also built.Eight indexes are selected,and the improved Analytic Hierarchy Process method(G1)is used to determine the index weight of the evaluation index system.Through the establishmeut of the mathematical formula of single index bearing capacity and the calculation of the model on the basis of the related indicator,the carrying degree of each indicator can be obtained.Then the water environment-carrying capacity of the Hanjiang basin is acquired based on the weighted calculation.The main factors influencing the water environment-carrying capacity are found through the analysis of the present status and dynamic changing tendency of the water environment-carrying capacity of Hanjiang basin.Consequently,the measures to enhance the carrying capacity is proposed.
