Guantian As An Example Research On Spatial Fractal Characteristics And Development Strategy Of Small Towns In Dongxihu District Under Suburban Integration

At present,with the proposal of the national rural revitalization strategy and the urban-rural integration development system and policy system,guiding the healthy development of small and medium-sized towns at all levels has become an important part of the current new urbanization construction.Although there have been a lot of researches on scholars in small towns,there are still some vacancies in the study of how the small towns in the suburbs are in harmony with the development of urban and rural areas,and some of the existing literature on the small towns has not yet been carried out.Classification,characteristics,and spatial assessment.Therefore,how to analyze the characteristics of suburban small towns from a new background,new theory and new methods in the context of urban-rural integration is the core issue of this paper.This paper follows the logical main line of "basic-dimension-feature-strategy" research,taking small towns in the east and west lakes as the research object,and taking the fractal feature measurement as the perspective.First of all,through the summary of basic theory and domestic and foreign research,this paper analyzes the current research direction and progress of suburban integration,small town space and fractal theory.At the same time,starting from the traditional research dimension of small towns and the influence of suburban integration on the spatial space of small towns,the fractal theory is introduced to construct a new framework of three-dimensional six-dimensional elements of spatial characteristics of small towns under suburban integration.The three-dimensionality is spatial form,hierarchical scale and Spatial structure,“six elements” are spatial boundaries,spatial forms,hierarchical scales,spatial agglomerations,spatial associations,and spatial coordination.Then,by analyzing and selecting the fractal dimension model,the fractal dimension model under the research dimension is constructed,and the fractal dimension is calculated for the three dimensions of urban space,and the boundary dimension and the spatial morphology evolution of small towns in the east and west lakes are The calculation of the radius dimension,using the expansion rate and compactness index for auxiliary analysis;the spatial level scale for the first degree and the order-scale method to measure;the spatial architecture for the aggregation dimension,the correlation dimension and the grid dimension The calculations are carried out,and the results of the calculation are analyzed to summarize the spatial fractal characteristics of small towns in the east and west lakes.Finally,aiming at the spatial fractal characteristics of small towns in the Dongxihu area,specific development strategies are proposed from the spatial three-dimensional,spatial form,hierarchical scale and spatial structure,in order to provide reference and suggestions for the development of small towns in the east and west lakes.
