摘  要：
从水资源、社会、经济和生态4方面选取20个指标构建了水资源承载力综合评价体系,采用主客观相结合的综合赋权法—AHP-熵权法确定各指标的权重,运用改进的TOPSIS法对连云港市2008-2016年的水资源承载力进行了评价。结果表明:2008-2010年连云港水资源承载力由Ⅲ级降低到Ⅳ级,2011年起提升至Ⅲ级,且在2012年达到最大综合评价值0.6506,此后承载力水平虽略有波动,但始终处于Ⅲ级中等水平,年均综合评价值为0.599 9。基于连云港市水资源现状,可采取注重农业节水、加大水利建设投资、充分利用雨洪资源、注重海水淡化等方法来提升该地区水资源承载力。

摘  要：
This paper selected twenty indicators from the aspects of water resources, society, economy and ecology to construct a comprehensive evaluation system for water resources carrying capacity,and used AHP-entropy weight method combined subjective and objective approach to determine the weights of each index,and the improved TOPSIS method was used to evaluate the water resources carrying capacity of Lianyungang during 2008-2016. The results show that: from 2008 to 2010,the water resources carrying capacity of Lianyungang decreased from Grade III to Grade IV; since 2011,it has risen to Grade III and reached the maximum evaluation value of0.650 6 in 2012; after that,although the level of carrying capacity fluctuates slightly,it is always at III medium level with an average annual evaluation of 0.599 9. Based on the current status of water resources in Lianyungang,the water resources carrying capacity of the region can be enhanced by increasing agricultural water conservation,paying attention to water conservancy construction investment,making full use of storm water resources and increasing seawater desalination.
