等斜率灰色聚类法在大气环境质量评价中的应用

A New Method of Air Environmental Quality Assessment——Isoslope Grey Cluster Method

对灰色聚类法中的白化函数进行改进，以等斜率方式构造梯形结构式的白化函数，提出了一种等斜率灰色聚类法，并以实例说明了该法在大气环境质量评价中的具体应用，最后与倍斜率聚类法和灰色聚类法进行了比较。结果表明，该法既能评价出各样本所属的污染级别，也能进行大气质量优劣排序，评价精度高，评价结果比较符合实际状况。

In this paper, the albefacted function of the grey cluster method was revised, a kind of laddre-shapped structural albefacted function was created in isoslope form, an isoslope grey cluster method was put forward and indicated by its practical application in air environmental quality assessment. A comparision between the double slope cluster method and the grey cluster method was made. The conclusion of the comparision was that the assessment result of using the isoslope method was more tally with the fact, and not only can it indicate the assessed samples pollution classes, but also range the samples by their environmental quality.
