城市环境空气质量排名方法比较研究

通过对空气质量排名中常用的综合指数法、最大指数法、内梅罗指数法、达标率排序法、污染物浓度排序法、层次分析加权综合指数法等多种方法的分析和比较,表明综合指数法和加权综合指数法能够兼顾各项污染物的贡献,可比性强,能够客观准确地反映不同城市空气质量状况优劣,适用于我国当前城市空气质量的排名。

STUDY ON COMPARING RANKING METHODS OF AMBIENT AIR QUALITY IN URBAN AREA

This paper analysed and compared some conventional air quality ranking methods，including composite index， maximum index，Nemerow index，air quality compliance rate，major pollutant concentration，weighted composite index based on AHP methods and so on． Results showed that the composite index and weighted composite index both could consider contributions from all kinds of air pollutants，had well comparability for all cities，and reflected the differences between air quality in cities subjectively and accurately． The two methods were suitable for ranking the cities according to their own air quality at present．
