区域大气环境质量灰关联评价方法探讨
Gray Association Analysis for Atmospheric Environmental Quality Evaluation in a Region
-
摘要: 针对区域中大气环境质量的特点,采用对数主成分分析方法获得各环境指标的权重及各监测点的横向排名,再用适宜的灰度关联方法进行了评价。整个过程在MATLAB6.5 中实现,计算简便易行,与传统的综合指数法相比较,其评价结果更符合客观实际Abstract: This paper applies the logarithmic principal component analysis to obtain the weight of index in environmental evaluation. The fitting gray association analysis is used in the evaluation. The whole process is realized in MATLAB 6.5. The computation is convenient, and the result accorded with the fact better than the traditional synthetic index method.
