摘要
文中基于2013年73个主要城市的截面数据,采用因子分析对城市发展水平进行了测量,采用相关分析探讨了城市发展水平与空气质量的关系,采用对比分析研究了不同年均降雨量下城市发展水平与空气质量的关系。研究发现:城市年均降雨极强的城市,不管其城市发展速度如何,城市空气质量都很好,极少有雾霾天气出现;城市年均降雨强度极低的城市,如果其城市发展速度较快,那么其空气质量非常不好,雾霾污染特别严重;城市年均降雨强度极低的城市,如果其城市发展速度不快和那些城市年均降雨强度一般的城市,不管其城市发展速度如何,城市空气质量的好坏与其高污染产业密集程度,煤炭使用量的多少、汽车拥有的数量和强度等因素密切相关。最后给出了我国应该加大城市空气污染自净能力研究的力度,科学划分出我国主要城市空气污染自净能力等级,并根据城市等级的不同有效控制其发展速度,规模,特别是其高污染产业如何发展等对策建议。
Based on the cross -sectional data of 73 major cities in 2013, this research measured the city devel- opment level by using factor analysis, explored the relationship between the city development level and air quality by using correlation analysis, and analyzed the relationship between the city development level and air quality under the different average annual rainfall using comparative analysis. The study finds that for the city with ex- tremely strong average annual rainfall, no matter how the city developed speedily, the city air quality was very good, the haze weather was rare; for the cities with extremely low average annual rainfall, if the city developed relatively fast, then the city air quality was very had, the haze pollution was specially serious; for the cities with extremely low average annual rainfall and modest city development speed, as well as the cities with modest aver- age annual rainfall and no matter how it developed, the city air quality was closely related to the intensive degree of high pollution industries, coal use, number and intensity of cars, and etc.
