摘要: 为了客观、综合地评价中国各城市的空气质量,制定有效的防治措施,选取SO2、NO2、PM10、O3、CO和PM2.5这6个指标作为评价因子,采用熵权法对各项指标赋权。结合TOPSIS法,建立空气质量评价模型,得到20个主要城市的空气质量排名。结果显示,这些城市对空气质量影响程度最大的3种主要污染物是SO2、CO和PM2.5,空气质量排名前3位的城市是深圳、宁波和上海。针对污染,提出了减少碳排放、推广清洁能源、强化保护措施、注重环保宣传和加强监管机制的建议。

Abstract: In order to objectively and comprehensively evaluate the air quality of each city in China and formulate effective prevention and control measures, the six indexes of SO2,NO2,PM10,O3,CO and PM2.5 were selected as evaluation factors, and entropy weight method was adopted to empower each index. Combined with TOPSIS method, the air quality evaluation model was established, and the air quality ranking of 20 major cities was obtained. The results showed that the three major pollutants were SO2,CO and PM2.5, and the air quality of Shenzhen, Ningbo and Shanghai was better than others. In view of pollution, some suggestions for reducing carbon emissions, popularizing clean energy, strengthening protection measures, paying attention to environmental protection publicity and strengthening supervision mechanism were put forward.

Key words: entropy weight TOPSIS method, city, air quality, evaluation
