摘要
针对当前国内对人口流动空间分布问题常采用的单一指标以及数理统计方法、忽略了空间效应、很难正确识别人口流动地域类型以及空间分布模式的问题,提出了一种以县域以人口净迁移率为横坐标和以人口总迁移率为纵坐标的复合指标法。首先对2010-2013年福建省85个县域的人口流动地域类型进行了测度和划分;随后,为进一步探索人口流动集聚程度,采用探索性空间数据分析方法进行了量化分析。结果表明:福建省县域人口流动空间分布差异显著;福建省县域人口流动的地理集聚特征显著且存在明显的正相关关系,并且"低-低"类型分布占据主要地位。研究结果为发现福建省县域人口流动空间模式,更好地为人口流动区域差异进行量化分析提供了强有力的支撑。
In view of the single index and mathematical statistics method,often used on the spatial distribution of population flow,which is difficult to correctly identify the type of population flow and spatial distribution patterns,this paper took the composite-index method consisting of two indexes：the net migration rate and the gross migration rate.First of all,the levels of population mobility of 85 counties in Fujian Province in 2010-2013 was measured and classified.Then,in order to further explore the level of global and local spatial aggregation of population mobility of all counties in Fujian,it took ESDA method to the quantitative analysis of Fujian＇s population mobility.The results show：The patterns of spatial distribute of Fujian＇s population mobility are significantly different.The patterns of spatial aggregation of Fujian＇s population mobility are also significantly different.There is a significant positive correlation among the counties in Fujian Province.And the latter accounted for a dominant position.The results provide a strong support in finding out the spatial patterns of population flow and quantitative analysis of the regional differences of population flow in Fujian province.
