模糊数学评价法在棋盘山水库水环境评价中的应用

为了综合评价棋盘山水库水环境质量,测试了棋盘山水库的高锰酸盐指数、化学需氧量、五日生化需氧量、氨氮、铜、总锌、铅、镉、氰化物、阴离子表面活性剂、硫化物等19项评价因子的浓度并对照地表水质量评价标准[1]进行了各个测试项目的水质级别分类,大部分检测项目均为Ⅰ类,只有氨氮和总磷为Ⅲ类水,直观上分析完全满足鱼虾等水生动物生存以及水产养殖。最后应用模糊数学综合评价法评价了棋盘山水库水质质量综合评价等级为Ⅰ类。

The application of fuzzy mathematical evaluation method in the Qipanshan reservoir of evalution of water environment

In order to evaluate the quality of water in the Qipanshan reservoir ,we measured concentrations of 19 factors,including permanganate index,chemical oxygen demand,the 5th biochemical oxygen demand,ammonia nitrogen,copper,total zinc,cadmium,cyanide,anionic surfactant,sulfide,fecal coliform,etc.We also classified quality level for each test item by comparing with evaluation standard for surface water [1].Most of the tested items are level I,except for ammonia nitrogen and total phosphorus that are both level III.However,in overall, the quality of water is fit for aquaculture and the living of aquatic organism such as fish and shrimp.Finally ,we classify the quality of water in the reservoir of Chessboard hill as level I by using comprehensive evaluation of fuzzy mathematical.
