山东省县域人口迁移的空间分异研究

A Study on the Spatial differentiation of population migration in Shandong Province Based on County

采用人口迁移综合指数分析了山东省138个县域人口迁移的空间分异,并利用空间关联指数探索了人口迁移的空间集聚模式。结果表明,山东省县域人口迁移具有明显的空间差异性,人口迁移地域类型随时间不断变化。其中,以人口迁移非活跃区和净迁出型活跃区的变化最为显著,前者数量显著增加而后者数量显著减少,空间分布格局变化大;平衡型活跃区的数量平稳增长,空间分布变化也较大;而净迁入型活跃区的数量和空间分布则相对稳定。山东省县域人口迁移的地理集聚特征显著且存在明显的正相关性,表现在济南和青岛市辖区不仅为人口净迁入型活跃区,同时也是人口净迁移率高-高集聚类型区;鲁西南的菏泽市不仅为人口净迁出型活跃区,同时也是人口净迁移率低-低集聚类型区,山东省以低-低类型分布占主要地位。

The spatial variation of population migration in 138 counties of Shandong province was analyzed by using the comprehensive index of population migration, and the spatial agglomeration model of population migration was explored by means of spatial association index. The results show： 1）Migration of county population in Shandong province has obvious spatial difference, and the spatial distribution of population migration varies with time. Among them, inactive region and net outflow population active region have changed dramatically： a significant increase in the number of the former and the latter number was significantly reduced. These spatial distribution pattern havemuch changed; The number of active area balanced type has been steady growth, and it＇s spatial distribution of the overall change is relatively large; The number and the spatial distribution of net inflow population activeregion is relatively stable. 2）The geographical agglomeration characteristics of county population migration in Shandong province are significant, and there is a positive correlation. Specific performance in Ji＇nan City and Qingdao City area is not only the net inflow population activeregion,but also the population migration high-high agglomeration region;Southwest Heze city is not only the net outflow population active region,but also the population migration low-low agglomeration region.As for the types of spatial distribution,the low-low agglomeration region accounted for a dominant position in Shandong Province.
