Research On Networking Trend Of County Towns And Villages System

With the acceleration,the wider scope and the larger scale of the flow of population,material,capital and other factors,the spatial reconstruction has spread from the global to the countryside.The macroeconomic and social development is characterized by globalization,while the microscopic spatial material form is represented by the networking trend of the village and town system.In order to empirically analyze this phenomenon,reveal the regular characteristics of the networking trend,with a view to achieving guidance for the planning of the village and town system,combining the actual needs of the reconstruction of the village and town system and the network and spacetime evolution trend from the "location theory" to the "network theory",the scientific problem is condensed as the " Networking trend of county towns and villages system ".In order to characterize the networking trend,it is a need to empirical analysis from the perspective of element flow and space-time evolution.To this end,cross-applying quantitative methods such as complex network analysis and mathematical analysis,using three types of elements and two time nodes to compare and demonstrate the networking trend of village and town’s spatial structure,digging the characteristics of evolution trend,summing up the evolutionary causes,and proposing optimization strategies.The main content and conclusions of the paper are as follows:First,a research plan oriented to the " Networking trend of county towns and villages system " was established,that is,"three types of elements,one target area,two time nodes,six models,and two types of indicators." From the important components that constitute the structure of the village and town system,three types of elements: enterprises,land use and highways are selected.A typical county-Changshou district with frequent two-way flow of urban and rural elements is selected as the research target area.Select two time nodes from 1985 and 2018 that can represent the different development stages of "location theory" to "network theory";on this basis,using complex network analysis methods,construct six network models of village and town based on three types of elementscorporation network,land use weight network,highway network and two time nodes-1985 and 2018,then establish two types of indicators to characterize the networking trend:network analysis and attribute analysis,which lays the foundation for empirical analysis.Second,the comparative empirical analysis based on three types of elements and two time nodes verifies the networking trend of the village and town spatial structure.Based on the corporation network,land use weight,and the highway network of the village and town spatial structure,the network indicators and attribute indicators from1985 to 2018 were analyzed.1)It is found that the evolution trend of the village and town system based on the enterprise network indicates that more villages and towns have established corporate links,and the connection strength increases;2)the evolution trend of the village and town system based on the weight of land use indicates that the village and town system spatial structure has an increasingly obvious polycentricity;3)the evolution trend of the village and town system based on the highway network shows that the road links between the villages and towns are increasing in the number of paths and connected accessibility enhanced.4)The correlation between the elements and the spatial aggregation distribution trend analysis reveals that the three types of elements have significant correlations,and from the random distribution state in 1985 to the "multicentric" pattern of spatial clustering and high-value aggregation in 2018.5)To sum up,the empirical analysis of the village and town spatial structure based on the enterprise network,land use weight and highway network validates the networking trend.Finally,on the basis of the networking trend,the planning thinking of the network development of the village and town spatial structure is proposed.1)Based on the enterprise network,land use weight and highway network,summarize the characteristics of the network trend from the three levels of Changshou district,group and village: from1985 to 2018,the functional connection between villages and towns showed a deterritorialization trend,the spatial pattern presents a trend of polycentricity and highway links show an integrated accessibility trend,the overall trend characteristics of the evolution from "single-centered,hierarchical,fragmented" in 1985 to "multi-centered,networked,and discrete" in 2018,and embody the dominant effect of town,core edge effect and cluster distribution effect.2)Through the analysis of the cause of network evolution,it is found that there are three reasons: the production and consumption shaping the functional space of villages and towns,the spatial production shift from city to town,and the time-space compression to reconstruct the village and town system spatial structure.3)Returning to the field of village and town system planning,the networking trend has practical guidance for the improvement of the functional structure of the village and town system,the optimization of the hierarchical structure,the prediction of spatial structure trends,and supporting policy support.Innovatively conversing element relationships based on the enterprise network,land use weight,and highway network into the modeling mechanism of the village and town spatial structure,from the perspective of "network",analyzes the evolution characteristics of the village and town spatial structure based on three types of elements;Constructing an index system that reflects the networking trend,based on the comparison of the spatiotemporal evolution of three types of elements and two time nodes,the networking trend of village and town spatial structure at the county level is demonstrated;it supplements the county-level village-level networking trend research sample.The empirical network trend of the village and town spatial structure was revealed,and its evolutionary characteristics were revealed.From the perspective of the networking trend of element relationships,the optimization strategy of the village and town system was explored,and the cross-research horizon of the village and town system and complex network analysis was expanded.
