浙江省单位GDP-PM2.5排放量可视化和内因分析

Visualization and Internal Cause Analysis of Unit GDP-PM2.5 Emissions in Zhejiang Province

由于经济增长、产业结构和空气污染密切相关,因此研究三者之间的动态关系对促进浙江省的可持续发展具有重要意义。本文选取了2015-2017年浙江省主要城市的GDP数据、人均GDP数据以及PM2.5数据,结合ArcGIS、Basemap进行以上数据的地理可视化分析,提出单位GDP/PM2.5排放量指标,可以直观地对比不同城市的单位GDP的PM2.5排放量。分析结果显示,浙江省温州市、衢州市的单位GDP的PM2.5排放量较低,即单位GDP的能耗较高,PM2.5排放量较高。浙江省需要在产业结构和产业类别等方面进行优化和调整,提高城市的可持续发展能力,降低单位GDP的PM2.5排放量。

Because of the close relationship between economic growth,industrial structure and air pollution,it is of great significance to study the dynamic relationship among them for promoting the sustainable development of Zhejiang Province.This paper chooses GDP data,per capita GDP data and PM2.5 data of major cities in Zhejiang Province from 2015 to 2017,carries out geographic visualization analysis of the above data combined with ArcGIS and Basemap,and puts forward the emission index of per capita GDP/PM2.5,which can intuitively compare the PM2.5 emission of per capita GDP of different cities.The results show that the PM2.5 emission per unit GDP of Wenzhou and Quzhou in Zhejiang Province is lower,that is,the energy consumption per unit GDP is higher,and the PM2.5 emission is higher.Zhejiang Province should optimize and adjust the industrial structure and industrial categories,so as to improve the sustainable development ability of the city and the PM2.5 emission per unit GDP.
