陕西省社会经济重心与环境污染重心的演变路径及其对比分析

本文在考察重心研究现状的基础上,提出了重心路径几何图示分析法,计算了1989-2003年陕西省社会经济重心与环境污染重心的演变路径,从移动方向、移动距离、路径对比、斜率分析、空间相关性分析等多角度阐述了社会经济重心与环境污染重心的动态变化及空间联系。

THE VARIATION TRACK AND CONTRASTIVE ANALYSIS ON THE SOCIAL ECONOMIC GRAVITY CENTER AND ENVIRONMENTAL POLLUTION GRAVITY CENTER IN SHAANXI PROVINCE

This paper brought forward the geometric analysis method of gravity center after analyzing the current research situation of gravity center.Adopting the data of population at the year-end(for population gravity center),GDP(for GDP gravity center),total investment in fixed assets(for investment gravity center),industrial waste gas(for waste gas gravity center),industrial waste water(for waste water gravity center),industrial solid wastes(for solid wastes gravity center) from the statistical yearbook of Shaanxi from 1989 to 2003,we calculated and analyzed the social economy gravity center and environmental pollution gravity center of Shaanxi province from different aspects of the shift direction,distance,slope,spatial correlate and contrastive route in longitude and latitude. We found that the population gravity center,GDP gravity center,waste gas gravity center and solid wastes gravity center of Shaanxi wore the dynamic tendency of higher longitude and higher latitude;the investment gravity center and waste water gravity center went towards the higher latitude with adverse turning.The social economy gravity center and environmental pollution gravity center correlated positive in latitude;in longitude,the population gravity center and GDP gravity center correlated positive with the waste gas gravity center and solid wastes gravity center,negative with the waste water gravity center;but in longitude,the investment gravity center correlated negative with the waste gas gravity center and solid wastes gravity center,positive with waste water gravity center.
