摘　　要：将模糊数学原理引入到湿地水质评价中,构建了淮盐高速公路沿线湿地评价体系。利用模糊综合评价法,对淮盐高速公路沿线6个采样点湿地的4次采样时间的水质进行综合评价。结果显示:2006年10月有4个采样点为Ⅲ类水质,其余2个采样点分别为Ⅱ类和Ⅳ类水质,说明高速公路的建设对沿线湿地水质影响不大。2007年7月的水质总体上明显劣于其他3次采样时间,有4个采样点为Ⅴ类水质,主要与夏季多雨引起土壤淋溶作用加强,输入到湿地中的氮磷养分增多有关。2007年4月和10月同2006年10月相比,水质状况总体变化不大,说明高速公路在1年的运营中对沿线湿地水质影响也不大。Abstact： Through the introduction of fuzzy theory into water quality evaluation of the wetland,this paper sets up an evaluation system for the wetland water along HuaiYan expressway. Making use of fuzzy comprehensive evaluation method,the water quality of 6 wetland sampling sites along HuaiYan expressway was evaluated at 4 sampling times. The results showed： it was indicated that the impact of expressway construction on the wetland water quality was little,because in Oct. 2006 the water quality of the 4 wetland sampling sites was of levelⅢ and the water quality of the other 2 wetland sampling sites was of level Ⅱ and Ⅳ respectively. That in Jul.2007 The water quality of the 4 sampling sites in July,2007 was of level Ⅴ,obviously inferior to that in the other 3 sampling times because in summer the more rain strengthened soil eluviation,which increasee the input of N and P into the wetland. It was indicated that in 1 year the impact of expressway operating on the wetland water quality was little since the water quality changed little during the period from Oct. 2006 to Apr. 2007.
