华南区域2000—2015年社会经济及环境污染重心空间演变对比分析

The variation contrastive analysis of economic gravity center and environmental pollution gravity center from 2000 to 2015 in south China region

通过对2000-2015年华南区域的GDP、年末人口、生活废水、生活COD、生活NH3-N、工业COD、SO2、NOX等排放量数据的收集及整理,利用区域重心的概念及模型,计算出区域十五年来的经济重心、环境污染重心坐标及偏移距离,从而揭示华南区域经济重心与污染重心的格局的动态变化及空间联系,为区域的经济增长和环境保护协调发展以及区域污染的空间治理提供宏观控制思路。结果表明:除工业COD排放量重心位于华南区域几何中心西南部外,区域其余指标重心均分布于华南区域几何中心的东部地区,人口、经济及各污染物排放集中于华南区域几何中心的东南部地区;经济在区域西部的发展速度要大于东部地区的发展速度,且在南北方向上趋于稳定平衡状态;环境污染整体向西北部移动,区域西部面临的环境压力不断增大。

Based on the data of gross domestic product(GDP),population,discharge of domestic pollution sources(including discharge of domestic water,chemical oxygen demand,ammonia nitrogen)and industry pollution sources(including discharge of chemical oxygen demand,ammonia nitrogen,sulfur dioxide and oxynitride)between 2000 and 2015 in south China region,the research group used the concept and model of regional gravity center to calculate the coordinates of economic gravity center,environmental pollution gravity center and the offset distance between them,expounding spatial evolvement track and its changes of economic and environmental pollution gravity center in the south China area.Then it provides the theoretical basis for the coordinated development of regional economic growth and environmental protection as well as the spatial control of regional pollution.The result shows as following information:firstly,all factors gravities,except industrial chemical oxygen demand,were located in the east of regional geometric center,and population,economic and environment pollution factors mainly focused in Southeast of south China area.Secondly,the pace of economic development in western region was faster than eastern region,and in northern and southern region,the space was stability.Lastly,the overall of environmental pollution moved to the northwest region and environmental pressures in western region increased constantly.
