农村居民收入空间分异机理研究——以河南省黄淮4市为例

Spatial differentiation mechanism of rural residents' income:a case study of Huang-Huai four cities in He'nan Province

基于空间界面视角,对河南省黄淮4市农村居民收入的空间分异机理进行探析.研究发现:黄淮4市农村居民收入大致呈现出南高北低的空间格局,没有明显的集聚特征,部分区域存在集聚态势;黄淮4市存在着多种空间界面,其中自然界面包括地形高差界面和干湿分区界面,人文界面包括省际交界界面、市区交界界面、高速系统界面、铁路系统界面和行政权力界面;地理探测器测算结果表明,行政权力界面、地形高差界面、干湿分区界面和高速系统界面对农村居民收入影响较大;黄淮4市农村居民收入空间分异是多界面综合作用的结果,且不同界面的界面效应有着显著差异.黄淮4市在自然界面的加成效应明显,地理区位界面的边缘效应不明显,交通系统界面的集肤效应有待加强,政策因素是影响农村居民收入空间分异的重要因素.

From the perspective of space interface, taking Huang Huai four cities in He＇nan Province, a typical rural region, as study region, the spatial differentiation mechanism of rural residents＇ income was analyzed. Firstly, the income generally showed that the spatial pattern there was higher in southern and lower in northern in the study re gion, and there were no obvious agglomeration characteristics, however there existed some clustered regions. Sec ondly, there were a variety of spatial interfaces in the four cities, and the natural interface included the terrain height difference interface and the dry wet interface, and the human interface included the interprovincial boundary inter face, the urban rural interface, the super highway interface, the railway interface and the administrative interface. Thirdly, the calculation results of geographic detector showed that there was a great influence on rural residents＇ in come in these interfaces including the administrative interface, terrain height difference interface, dry wet interface and the super highway interface. Fourthly, the spatial differentiation of rural residents＇ income in the four cities re suhed from comprehensive interactions of different interfaces, and the effects of different interfaces were significant ly different. The additive effect of the natural feature interface was obvious, the edge effect of the geographical loca tion interface was not obvious, the skin effect of the interface of the transport system needed to be strengthened, and policy factor was an important factor that affected the spatial differentiation of rural residents＇ income.
