摘　　要：根据对南湖公园水质的监测数据建立评价因子集,根据环境质量标准的5个等级建立评价等级集,选择降半梯形分布来确定隶属函数,建立模糊关系矩阵,采用超标倍数赋权法确立权重系数,构造权重系数矩阵,将模糊矩阵和权重矩阵进行合成,得出南湖公园水质综合评价结果。结果表明:南湖公园的水质基本达到Ⅴ级标准,基本满足地表水水域环境功能,但部分娱乐用水区水质存在污染。与其他方法的比较结果表明,该模糊综合评价法较好地解决了质量分级归属问题,采用超标倍数赋权法确立权重得到了比较客观的结果。The evaluating factor congregation was set up according to the monitoring data of Nanhu Park water quality. The evaluating grade congregation was established based on 5 grades of environmental quality standard. The subordinate function was confirmed to establish fuzzy relation matrix by selecting the falling semi-trapezoid distribution. The weight coefficient was confirmed to construct weight coefficient matrix by using super-standard multiple weight method. And the comprehensive evaluating results on water quality of Nanhu Park was got by combination of fuzzy relation matrix and weight coefficient matrix. The results showed that water quality in Nanhu Park was W degree,and basically met the need of surface water environmental function. However,water quality in part of entertainment area was polluted. Compared with other methods, this method of fuzzy comprehensive assessment better solved the adseription question of quality grade. Using super-standard multiple weight method to establish weight coefficients could obtain more objective results.
