OPTIMIZING THE SPATIAL PATTERN OF VILLAGES AND TOWNS BASED ON SOCIAL NETWORK ANALYSIS——TAKING SHIMEN COUNTY,HUNAN PROVINCE AS A CASE STUDY
The 19th National Congress of the Communist Party of China proposed the implementation of the rural revitalization strategy.With urbanization and the reconstruction of rural space,optimizing the spatial pattern of villages and towns within a county can effectively promote urban-rural integration and rural revitalization.This study took social network analysis as the core,proposed an optimization process for the spatial pattern of county towns and villages,and followed the steps of evaluating the status quo,identifying problems,and conducting spatial optimization,then systematically constructed a spatial pattern optimization process for county towns and villages by combining various research methods such as the gravity model,social network analysis,and the rank-size rule.The gravity model was used to explore the interaction pattern of villages,social network analysis was used to reveal the group structure,and the rank-size rule was used to quantify the polarization degree of clusters.Finally,the problems existing in the spatial pattern of villages and towns were identified,and spatial optimization approaches were proposed in combination with the regional characteristics of each cluster.Taking Shimen county,Hunan province,as the case study,the results showed that:(1)The overall spatial connection network density stability of Shimen county was not high,and the connections between villages were weak,showing a typical circular layered network structure.(2)The villages in Shimen county could be divided into five blocks,and the interactive gravity decreased from the southeast block to the northwest block.(3)The polarization effect and factor agglomeration degree of each block at this stage were low,and the agglomeration of factors needed further promotion.In summary,this research reveals that the spatial connection of villages in Shimen county is insufficient and that the existing administrative division units cannot meet the requirements of village group development.In the future,it will be necessary to strengthen the overall planning of a county as a whole from the perspective of villages and towns,promote industrial development planning and the communication of production factors as a whole,and give full play to the radiation and driving role of the cluster center.A'one core,multiple centers'spatial development model can be formed within a cluster,where each center attracts enterprises that build corresponding links in the industrial chain.
