四川省人口与经济空间分布关系分析

Analysis of the Relationship between Population and Economic Spatial Distribution in Sichuan Province

采用地理集中度、人口经济一致性系数、空间自相关分析方法对四川省180个区县2000年和2013年的人口和GDP数据进行空间分布关系分析.结果表明:1四川县域人口、经济空间分布不均衡,呈现东部成都平原及川中丘陵集聚度高,西部高原高山区集聚度低的格局,东部集聚西部分散的特点.2人口与经济空间分布关系以人口集聚超前于经济集聚型为主,目前正朝人口经济协调型的区域类型发展.3四川省各区县的人口经济一致性系数在空间上趋于集聚且集聚程度逐年增强.

Based on population and economic data of 180 counties of Sichuan province in 2000 and 2013,this paper applied geographic concentration,the spatial consistency index,spatial autocorrelation to analyze the spatial distribution relationship between population and economy. The results show as follows： The firstly,the spatial distribution of population and economic is lopsided. The spatial distribution is concentrated in the east and scattered in the west. The eastern Chengdu Plain and Middle Sichuan Basin is high concentration and the western plateau mountain is low concentration. The secondly,the concentration of population more than the concentration of economy is dominant in the relationship between population and economic. Tendency of their relationship is that population is coordinated with economy. At last,there is prominent spatial autocorrelation of the spatial consistency index in all counties. These counties with the higher or the lower index locate together.
