摘    要:对在环境质量评中应用的灰关联分析方法进行了探讨,认为实际上评价标准是区间概念而非 的概念,因而传统灰联分析处理曲线间几何形状接的方法存在一定缺陷。为了改进这种缺陷,提出了一种基于点到区间距离的关联系数公式,并把它用到水环境质量评价虽,发现这种改进的灰关联分析方法具有更大的适应性。

关 键 词:水环境  质量评价  灰关联分析法  水质

Abstract:The gery association analysis method,which is applied in environmental quality assessment,is discussed in this paper Since the assessment standard actually is not a point but an area,a defect exists in the traditional grey association analysis method which disposes the geometry closing degree between curves.In order to overcome the defect,a new association analysis method,which is based on the distance from point to area,is put forward in this paper and is applied in water quality assessment.It shows that this improved grey association analysis method is more rational than the traditional one.
Keywords:water environment  quality assessment  grey association analysis method  improvement of method
