Characteristic Analysis of Spatial Structure of Rural Territorial System and Development Types:Taking Bin County of Heilongjiang Province as an Example
The purpose of this study is to construct the multidimensional spatial structure of Bin County based on the multibody system theory of rural territorial system,to provide experience for exploring the spatial optimization scheme. The research methods include Entropy-TOPSIS method,gravity model,K-means clustering,geodetector and spatial analysis. The research results show that 1) based on the multidimensional structural framework of "pole-field-area-network" in the theory of rural territorial system,six rural revitalisation poles,four village and township spatial fields,and ten rural development areas in Bin County are identified and divided,and a spatial interconnection network of rural territorial system is constructed. The spatial interconnection network of rural territorial system is constructed. 2) The comprehensive development levels of villages and towns show obvious regional differences,with high level areas forming a small-scale agglomeration,showing a spatial layout of "high in the west and low in the east". 3) In general,the spatial element aggregation links and zoning characteristics of urban-rural basic network in Bin County show non-equilibrium,and the high gravitational value network is mainly distributed around the core area of towns in the west of the county,forming an obvious polar axis network around the core area of towns to the west. In conclusion,the multidimensional structural framework of "pole-field-area-network" can effectively identify the growth axes and development poles of rural territorial system and locate the optimal comprehensive development path of rural territorial system by gravitational characteristics.
