直辖市空气污染指数比较分析

Comparative Analysis of Air Pollution Index in the Municipalities Directly under Central Government

以重庆市、北京市、天津市、上海市四大直辖市2001-2011年的大气主要污染物的排放量为基础数据,建立API空气污染指数模型,计算出各污染物的分指数,并利用模型中的分指数,通过层次分析法,得出污染物各自的权重;根据目前直辖市大气污染的现状,以及主要污染源中的主要污染物的状况,结合各地的"十二五"发展规划,提出改善各直辖市空气环境质量的建议和对策。

By taking the main pollutants in the air in Chongqing, Beijing, Tianjin and Shanghai during 2001- 2011 as basic data, API air pollution index model is set up, the sub-indicator of each pollutant is calculated, the weight of each pollutant is obtained by using the sub-indicator of this model and via analytic hierarchy process, and the suggestions and measures for improving air environment quality in the four municipalities are advanced according to the status quo of the pollution in the four municipalities and the situation of the main pollutants in the chief pollution sources as well as based on ＂the Twelfth Five-year Development Plan＂ in each place.
