社会经济与环境污染时空演变及动力机制分析——以重庆市为例

Spatio-Temporal Evolution and Dynamic Mechanism Analysis of Social Economy and Environmental Pollution—Taking Chongqing as an Example

摘要: 本文基于2007~2016年重庆市县级尺度数据，从多个角度阐述社会经济重心与环境污染重心的动态演变与空间联系，并通过空间差值法进一步分析其演变特征与动力机制。结果表明：1) 重庆市社会经济重心与环境污染重心均位于几何重心西南部，呈现分布的不均衡性；2) 除人口重心，其它要素分布逐渐均衡化；3) SO₂排放、GDP重心变化较为剧烈，人口重心相对稳定；4) GDP、工业产值分布整体差异缩小，环境状况总体改善，但仍存在局部污染中心。

Abstract: Based on the data of county-level scales in Chongqing from 2007 to 2016, this paper explains the dynamic evolution and spatial connection between the socio-economic center of gravity and the center of environmental pollution from multiple perspectives. This paper further analyzes the spatio-temporal evolution characteristics and dynamic mechanism of social economy and envi-ronmental pollution through the spatial interpolation method. Chongqing’s social economic and environmental pollution gravity centers are located in the southwest of the geometric center of gravity, showing an uneven distribution. In addition to the migration of the population’s gravity centers, the distribution of other elements gradually equalizes. The changes in SO₂ emissions and GDP gravity centers are more dramatic, and the population gravity centers are relatively stable. The overall difference in GDP and industrial output distribution has narrowed, and the environmental conditions have generally improved, but some pollution centers still exist.
