摘　　要：为了探讨中国城镇生活源污染与社会经济发展之间的关系,引入重心的概念,利用经济空间结构的重心计算方法,结合1998-2008年中国各省的生活污水排放量COD排放量,NH3-N排放量GDP,人口,居民可支配收入等统计数据,计算出各年的城镇生活源污染重心和经济重心的演变路径,从移动距离、移动方向、路径对比、空间相关性分析等多角度阐述了经济重心与城镇生活源污染重心的动态变化及空间联系.结果表明,不同的重心存在着很大的偏离,经纬度空间上,人口及居民可支配收入与城镇生活源污染重心呈负相关,GDP与城镇生活源污染重心正相关.There is a strong correlation between urban residential pollution and social-economic development in China. The method of gravity center shift is adopt to examine the shift of both economic gravity center and pollution gravity center in this study. Firstly, statistical data between 1998 and 2008 were collected from statistical yearbooks, with domestic sewage discharge, discharge of COD, and discharge of NH3-N for pollution factors, and GDP, population, and disposable income of residents for economic factors. Secondly, regional pollution gravity center and economic gravity center were calculated accordingly. Their dynamics and spatial relationship were illustrated and compared in terms of distance of shift, deviation of shift, comparison of pathway, and their spatial relationship. The results show an obvious deviation for different gravity centers. In longitude, it shows a negative correlation between the gravity center of population with gravity center of domestic sewage discharge, discharge of COD, and discharge of NH3-N, a positive correlation between GDP and COD, NH3-N, and a negative correlation between disposable income of residents and gravity center of urban point-source residential pollution. In latitude, the social and economic gravity center shows a positive correlation with gravity center of COD, and NH3-N. The gravity center of urban point-source residential pollution exhibits a negative correlation with gravity center of GDP and disposable income of residents, and a positive correlation with gravity center of population.
