河南省1987-2006年人口重心与经济重心的空间演变及对比分析

Evolvement and Comparative Analysis of Population Gravity Center and Economy Gravity Center from 1987 to 2006 in Henan

利用区域重心的概念及模型,计算了1987-2006年河南省的人口重心和经济重心;运用GIS软件制作人口重心、经济重心的空间演变轨迹地图,分析了人口重心和经济重心的动态变化及其驱动因子。结果表明:河南省人口、经济呈现不均衡分布,人口分布主要表现为东西不均衡,东部人口密度高于西部;经济格局主要表现为南北差距,北部经济优于南部。人口、经济重心偏离较大,表明河南省区域差距的扩大已经影响经济的进一步发展。

Taking the conception and model of the regional gravity center and adopting the data collecting from each district from 1987 to 2006, this paper calculates the population gravity center and the 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. And use GIS software to make the space evolution map of the center of gravity of population and economy, The results shows that the distribution of population and economy of Henan Province is disequilibrium, The main characteristic of the population distribution is imbalance between east and West, the eastern part of the population density is higher than the west; The main pattern of economic is the gap between North and South, the northern part of the economy is better than the South, deviation of demographic and economic center of gravity of Henan Province indicate that the larger gap of the regions in Henan Province has effected further development of the economy.
