基于ESDA的太湖流域空气质量时空异质性分析

以长三角核心区域——太湖流域对研究对象,对其2014—2018年空气质量进行了时空异质性分析,并利用相关性分析探索了太湖流域空气质量驱动机制。结果表明:(1)太湖流域空气质量的总体空间差异较小,流域东部沿海沿江地区以及西南部山林区域的空气质量普遍较好。上海、嘉兴两市空气质量相对较好,无锡、镇江两市则较差,局部聚集性尚不明显;(2)自然生态空间、污染治理技术及协同治理对策可使城市在经济社会发展的同时实现空气质量的稳步改善。最后结合流域实际针对性提出了相适应的对策建议。

Spatio-Temporal Heterogeneity Analysis of Air Quality in Taihu Basin Based on ESDA

Taking the Taihu basin,the core region of the Yangtze River Delta,as the research object,this paper analyzes the spatio-temporal heterogeneity of air quality in 2014-2018,and explores the driving mechanism of air quality by correlation analysis.Results show that:(1)the overall spatial difference of air quality in Taihu basin is small,and the air quality in the eastern coastal areas and the mountainous areas in the southwest is generally better.The air quality of Shanghai and Jiaxing is relatively good,while that of Wuxi and Zhenjiang is poor,and the local aggregation is not obvious so far.(2)Natural ecological space,pollution control technology and coordinated control countermeasures can make the city achieve steady improvement of air quality along with socio-economic development.Finally,the corresponding countermeasures and suggestions are put forward according to the actual situation of the Taihu basin.
