基于统计分析的江苏省雾霾影响因素研究

Research on the Influential Factors of Fog in Jiangsu Province Based on the Statistical Analysis

为对江苏省雾霾的治理提出有针对性、科学有效的措施,综合运用多元统计分析、主成分分析和因子分析等方法,对江苏省各地级市的雾霾影响因素和空气质量指标(AQI)的关系进行了对比分析。结果表明:江苏省第二产业占比、面积和人均机动车拥有量与雾霾污染均呈负相关。最后提出江苏省第二产业占比小和占地面积小的城市应更加注重雾霾污染的防治,江苏省人均机动车拥有量小的城市应更加重视制定和执行限制机动车排放的相关规定,江苏省13个地级市应更加注重雾霾防治的经验交流,进行多城市联合治理雾霾。

In order to put forward targeted for fog haze of governance in Jiangsu Province, scientific mid effective measures, multivariate statisti- cal analysis method, principal component analysis, factor analysis and other methods are integrated to study relationship between AQI and haze influence factors of each city in Jiangsu Province. The result showed that the proportion of the second industry, area and per capita volume of mo- tor vehicles of Jiangsu Province have a negative correlation with the fog and haze pollution. Finally, the second industry of Jiangsu Province area than small and should pay more attention to the city covers an area of prevention of haze pollution, vehicle ownership per capita in Jiangsu Prov- ince small city should pay more attention to the formulation and implementation of the relevant provisions of restrictions on vehicle emissions, 13 prefecture level cities in Jiangsu Province should pay more attention to the haze prevention of the exchange of experience, multi city joint govern- ance haze.
