基于AHP模型评价武汉市大气环境质量

Atmospheric environmental quality assessment for Wuhan with analytic hierarchy process model

通过层次分析法对武汉市2009—2015年大气环境质量进行评价,结果表明:武汉市2009—2015年,大气环境质量一直处于二级标准,其中2014年的大气环境质量最好,2009年的大气环境质量最差.武汉市大气环境质量受PM10和NO_2的影响较大,受SO_2的影响较小.PM10和NO_2对武汉市大气环境质量影响的权重值逐渐变大,而SO_2的权重值影响逐渐变弱.从总的变化趋势来看,武汉市的大气环境质量级别正从二级向一级转变,大气环境质量呈现出改善的趋势.

This research assessed atmospheric environmental quality of Wuhan from 2009 to 2015 with the method of analytic hierarchy process（ AHP）. The assessment indicated that the atmospheric environment quality had been in the secondary standards,of which 2014 year of atmospheric environment quality was best,atmospheric environment quality of the worst in 2009. Wuhan City atmospheric environment quality was strongly influenced by PM10 and NO2,the influence of SO2 was smaller. PM10 and NO2weight value of effects of atmospheric environmental quality in Wuhan City increased gradually, and the impact of SO2 was decreasing. From the point of a general trend of change,the atmospheric environmental quality level of Wuhan City was transition from secondary to primary,presented the improvement trend of atmospheric environment quality.
