摘要
本文运用地理集中指数和区域重心,借助GIS与空间自相关技术,研究1990~2010年长江中游城市群人口与经济空间分布关系。研究结果表明,长江中游城市群人口与经济集聚具有东北一西南高,东南低的空间分布特征,且形成武汉、长沙和南昌3大极化区域。长江中游城市群人口和经济具有空间集聚的分布特点,形成高值或低值簇,而且经济集聚程度高于人口集聚程度。根据人口与经济集聚协调程度,将长江中游城市群31个区域划分为3种基本类,即人口与经济集聚协调型,人口滞后于经济集聚型和人口超前于经济集聚型。长江中游城市群人口与经济重心大致向东南方向偏移。区位条件、区域政策以及区域发展的历史基础是影响长江中游人口与经济空间分布关系的主要因素。
Using the index of population concentration, economic concentration, and GIS technology and spatial auto-correlation technology, this paper analyzes the relationship between population and e- conomic spatial distribution in urban agglomerations in the middle reaches of the Yangtze River from 1990 to 2010. The results show that the spatial characteristics of the population and economy are ob- vious in the northeast and the southwest rather than in the southeast, with the three polarizable re- gions of Changsha, Wuhan and Nanchang.. In the light of the self-correlation of regional population and economic spatial distribution, the research concludes that the typical feature between the popula- tion and the economy in this region is in a spatial agglomeration, forming a high cluster or a low clus- ter. The level of economic agglomeration is higher than that of population agglomeration. According to the coordination degree of population and economic concentration, the areas are divided into three types: the coordination of population and economic agglomerations, the population lagging behind the economic agglomeration, and the economic agglomeration lagging behind the population agglomera- tion. The population and economic center in the middle reaches of the Yangtze River moved gradually to the southeast from 1990 to 2010. The main factors influencing the relationship of the spatial distri- bution between population and economy are the geographic conditions, regional policies and regional development.
