| 摘 要： | 传统的模糊评价模型确定指标权重的方法带有片面性,评价结果有时不能全面真实地反映水质状况.应用改进的模糊综合评价模型探讨了长江近两年的水质状况.首先根据各评价指标浓度的超标值,定义了权重计算公式,从而确定每种评价因素的权重.其结果综合了各种污染指标,对各观测站点的水质做出了比较合理的评价.

| Abstract: | The way of calculating index proportion of traditional fuzzy evaluation is unilateral,and sometimes the result can not reflect the water quality.This paper discusses the water quality of Yangtze River in the recent two years by applying modified fuzzy comprehensive evaluation model.According to the concentration superscale of each evaluation index,defines the computing formulas of index proportions,and then calculates index proportions through it.The results synthesize various kinds of pollution index basically,and makes rational evaluation on the water quality of every observation station. |
