中国流动人口通婚圈地域结构分析

Study on the Spatial Structure of Chinese Floating Population's Geographic Inter-marriage Circle

本文使用2011—2013年中国流动人口动态监测数据,利用空间分析方法对流动人口地理通婚圈的地域模式与圈层结构进行分析发现:不同区域之间的通婚地域模式具有显著的差异,东部地区的跨省通婚明显高于东北地区和西部地区,中部地区处于最低水平。地理通婚圈的空间圈层结构不但呈现出"空间等级分层"的物理结构,而且不同圈层本身的结构形态也存在显著的差异。地理通婚圈结构自内向外,出现了通婚圆→通婚弧→通婚点的梯度演化。此外,地理通婚圈分异还具有一定的方向偏好。

This paper, based on the data of 2011-2013 dynamic monitoring survey of Chinese floating population, adopts the spatial analysis method to study the regional model of geographic intermarriage circle and its spatial structure. The findings show that geographic inter -marriage model differs significantly among regions, and the eastern region boast of significantly higher cross-provincial marriage than Northeast and Western, but the central region unexpectedly boast of the lowest. The geographic inter -marriage distributes with differentiated special structures with significant differences within them. The geographic inter-marriage$ s spatial distribution show a gradual change from circle region to arc region then to dotted areas. In addition, the geographic intermarriage spatial distribution shows some direction-oriented stretching.
