灰色关联度在水污染因素分析中的应用

The Application of Grey Incidence Degree in the Analysis of Water Pollution

灰色关联度分析法是根据因素之间发展态势的相似或相异程度来衡量因素间关联的程度,其实质是用几个数列曲线间几何形状的差别判断关联程度。通常可采用初值化或均值化的方法计算关联度。对废水排放总量及人均废水排水量的影响因素进行分类并用关联度进行分析找出了人口数量和废水治理水平是其主要影响因素。

This paper introduces the data difference matrix to make the method of incidence degree easer,analyzes the factors influencing the water pollution,and finds the major factor. This will benefit our sustainable development.
