摘要
基于中国31个省会直辖市城市的空气质量和社会经济指标数据,以STIRPAT模型为分析工具,分析了城市空气质量现状及其社会经济影响因素。结果表明:2013—2017年,AQI年均值呈线性下降趋势,月均值呈U型曲线。空气质量不理想的城市主要分布于华北、华东、华中、西北地区。根据空气质量可将样本城市分为三个等级。技术与产业结构因素对城市空气质量有显著的影响,人口、财富、交通、绿化等因素对空气质量的影响不显著。最后,为进一步提高城市空气质量提出了政策建议。
Based on the air quality and socio-economic data of 31 provincial capital cities,the present situation of urban air quality and its social and economic influencing factors were analyzed by the extensible random environmental impact assessment model(STIRPAT model).The results showed that the annual mean value of AQI implied a linear downward trend,while the monthly mean value curved a U-shaped from 2013 to 2017.Those cities with poor air quality are mainly located in North China,East China,Central China and Northwest China.The sample cities could be divided into three grades according to their air quality.Technology and industrial structure factors had a significant impact on urban air quality,while population,wealth,transportation,greening and other factors had no significant impact on air quality.Some policy suggestions were put forward to improve urban air quality.
