指标规范值的灰色聚类用于大气环境质量评价

An Air Quality Assessment Based on Grey Cluster of Normalized Index Specification

为减少传统的灰色聚类法用于空气质量评价时涉及到白化函数的设计工作量,在设定空气指标"参照值"和"规范变换"基础上,将同级标准规范值相近的指标归为一类,属于同一类的指标设计为相同的归化函数,简化了函数的计算。将指标规范后的聚类分析方法应用于大连市区空气质量评价,结果表明:该方法用于空气质量评价具有简单、方便和实用的特点。

In order to reduce the workload of designning white functions in traditional grey clustering application in the air quality assessment,on the basis of setting the target reference value and normalized transformation of those indexes were bracketed together in the same standard which had the similar value,and subsequently designed as the same white functions.So the calculation of the function was simplified.This method of index clustering analysis was applied in the air quality assessment in Dalian City.The results showed that the method was simple,convenient and practical.
