摘要
利用PM2.5等6种污染物数据、社会经济数据和气象数据,运用空间计量方法和相关分析法研究环长株潭城市群雾霾污染的时空特征及其驱动机制。结果表明:(1)从时间变化来看,环长株潭城市群雾霾污染月均值变化特征为先降后升,夏季最低,冬季最高;(2)从空间格局来看,长沙、株洲、湘潭以及益阳雾霾污染严重,娄底和衡阳雾霾污染程度较轻;(3)产业结构、人口因素、经济发展、能源因素、城市建设等对雾霾污染产生正向影响,而气温等条件对雾霾污染有减弱作用。
Based on the data of PM2.5 and other six pollutants,socio-economic data and meteorological data,and using the spatial econometric method and related analysis methods to study the spatial and temporal characteristics of urban haze pollution in the City Group Around Changsha-Zhuzhou-Xiangtan and its driving mechanism.The results show that:(1)From the time change,the monthly mean change of urban haze pollution in Hunan Province is the lowest in summer and the highest in winter.(2)From the spatial pattern,the haze pollution in Changsha-Zhuzhou-Xiangtan and Yiyang is serious,while the haze pollution in Loudi and Hengyang is low.(3)In the industrial structure,population factors,economic development,energy factors,urban construction and other factors that have a positive impact on haze pollution,and the temperature has a negative effect on haze pollution.
