Taking the conception and model of the regional gravity center and adopting the data collecting from each province (city or district) from 1978 to 2002, this paper calculates the population gravity center and the social economy gravity center yearly, figures out the dynamic evolvements of these two gravity centers and analyzes the dynamic change of the population and economy regional differences and their related causes and at the same time, makes a contrastive analysis of the dynamic evolvement tendencies of the two gravity centers. The results show that the population gravity center makes a slow and steady move to southwest China since the opening up and reform of the country, which indicates that the population distribution tends to equilibrium in the longitude direction, however, it is disequilibrium in the latitude direction. GDP gravity center also moves to southwest China from 1978 to 1991, which indicates that the economic development differences are lessening in the longitude direction, however they are widening in the latitude direction. From 1991 to 2002, the GDP center moves to the southeast, which indicates that the economy regional development differences are widening both in the latitude direction and the longitude direction. The secondary industry gravity center also moves to southwest, which indicates that the differences in the longitude direction is lessening, however it is a little widening in the latitude direction. But the third industry and the social consumption centers move to southeast all the while, which indicates that differences are widening in both directions. However the first industry dose not show obvious change because the first industry mainly consists of the agriculture industry and the whole agriculture development level is low. The agriculture production depends on much natural condition, which leads to the randomicity of the agriculture distribution. Against the geometry center of China, the regional differences in general are widening. Against the population center, the social economy takes on imbalanced development in the longitude direction; however it tends to balance in the latitude direction.

本文利用区域重心的概念及其模型,计算了1978-2002年我国逐年的人口重心和社会经济重心,得到人口重心和社会经济重心的动态演变轨迹,分析了人口和社会经济发展区域差异的动态变化及其驱动因子,并对人口重心和社会经济发展重心的动态演变趋势进行了对比分析。

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...

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.

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。
