摘要
城市空气污染问题已经严重阻碍了城市的可持续发展。基于2015-2017年空气质量(AQI)日报数据,利用空间自相关及空间回归模型探究中国城市空气质量的时空演变特征、空间溢出效应及影响因素。结果表明:(1)2015-2017年中国空气污染城市逐渐减少,空气质量有所提高;(2)中国城市空气质量AQI季节均值在空间上基本呈现出北高南低、内陆高沿海低的分布格局。基本为冬季>春季>秋季>夏季;(3)中国城市空气质量空间差异特征较为明显,空间依赖性特征显著,空气污染较为严重的区域主要分布在我国的黄淮海地区及华北地区;(4)中国城市空气质量的空间溢出效应明显,影响城市空气质量因素众多,其中城市工业结构对城市空气质量的影响程度最为显著。
The problem of urban air pollution has seriously hindered the sustainable development of cities.Based on the air quality(AQI)daily report data from 2015 to 2017,the spatial autocorrelation and spatial regression models are used to explore the temporal and spatial evolution characteristics,spatial spillover effect and influencing factors of air quality in Chinese cities.The results show that:(1)China’s air pollution cities have gradually decreased from 2015 to 2017,and air quality has improved.(2)The AQI seasonal average of Chinese urban air quality basically presents a spatial distribution pattern of being high in the north and low in the south,and high in the inland and low in the coast.The basic order is winter>spring>autumn>summer.(3)The characteristics of spatial differences in air quality in Chinese cities are relatively obvious,and the characteristics of spatial dependence are significant.The areas with more serious air pollution are mainly distributed in Huang-Huai-Hai region and North China.(4)The spatial spillover effect of air quality in Chinese cities is obvious.There are many factors affecting urban air quality,among which urban industrial structure has the most significant impact on urban air quality.
