摘要

在综合分析区域水环境特点的基础上选取了7项研究指标，运用模糊物元模型与熵权法计算了烟台市牟平区2005-2009年各年水环境承载力与标准样本之间的贴近度，揭示了区域水环境承载力的现状及变化趋势。研究结果表明，烟台市牟平区2005-2009年水环境承载力与标准样本之间的贴近度分别为0.675 9，0.684 2，0.666 7，0.675 3和0.696 1，研究区域2006和2009年的水环境承载力达到等级Ⅲ水平，其余几年均在等级Ⅲ水平以下，说明研究区水环境承载力较差。并基于水环境承载力现状对区域资源与社会经济的可持续发展提出了相关建议。

Abstract

In order to demonstrate the status and the trend of water environment carrying capacity，the fuzzy matter-element model coupled with entropy weight method was adapted to calculate the proximity between the water environment carrying capacity and standard samples in the area of Muping district，Yantai City from 2005 to 2009． A total of seven indices were selected． The results show that the proximity between the water environment carrying capacity and standard samples were 0． 804 7，0． 684 2，0． 666 7，0． 675 3，and 0． 696 1 from 2005 to 2009，respectively． The water environment carrying capacity were at level Ⅲ in 2006 and 2009，while the other three years were under level Ⅲ，indicating poor water environment carrying capa-city of the investigated area． Furthermore，suggestions were made on improving the water environment carrying capacity and promoting the sustainable development of society and economy．
