摘    要:通过对空气质量排名中常用的综合指数法的优缺点进行分析,提出了一种基于层次分析法的加权综合指数排名方法,根据每种污染物的重要性不同,赋予各污染物相应的权重,进行了城市间排名测算分析。结果表明,加权综合指数法兼顾了各项污染物对空气质量的贡献,又能够重点突出主要污染物的贡献,各城市间可比性强,能够客观、准确、公平地反映不同城市间空气质量状况差异,能满足当前中国城市环境空气质量排名工作的需要。

关 键 词:空气质量  排名方法  层次分析法

Abstract:Analyses the merits and demerits of composite index method, a conventional air quality ranking method, then proposes a weighted composite index methods based on AHP(analytical hierarchy process), according to the importance of each pollutant, endow the different weight for them, then estimate this method based on some cities' air quality data. Results shows that the weighted composite index method based on AHP cannot only consider contributions from all kinds of air pollutants, but also can reflect the major pollutant's effect. So the new method is comparable for all cities, can reflect the differences about air quality among the cities fairly, objectively and accurately, and is suitable for ranking the cities according to their own air quality at present.
Keywords:air quality  ranking method  AHP(analytical hierarchy process)
