Multi-function evolution and development path of suburban villages at village scale:A case study of Tongshan District,Xuzhou City
Suburban areas are a typical area for rural multi-functional development.With the rapid advancement of non-agricultural development,urbanization,and industrialization,the development of suburban villages faces diversified needs,resulting in spatial mismatch and functional confusion,which urgently needs scientific guidance and regulation.Therefore,we selected Tongshan District of Xuzhou City,a typical suburban area,as the study area,and village area as the basic spatial unit and used a total of 319 administrative villages as samples.By constructing a multi-function evaluation indicator system for the area,we examined the spatiotemporal characteristics of change of rural economic development,agricultural production,ecological conservation,and living security during 2009-2019.Spearman correlation coefficient was used to analyze the interaction among the four functions.In order to further explain the spatial heterogeneity of functional interactions,the geographically weighted regression model was introduced to explore the spatial heterogeneity of functional interaction,and regression coefficient was used to further determine the small-scale functional interactions.On this basis,the article summarized the type of functional change and the regulation path of suburban rural development.The results show that:1)At the village level,in the 10 years between 2009 and 2019,the differentiation of quantitative structure and the agglomeration of spatial pattern of regional multi-function change coexisted.2)According to the correlation and interaction evolution process of rural regional functions,the overall relationship and local relationship of functional interaction evolution were consistent,but there were some differences,which can be summarized into five functional evolution types.3)The evolution path of rural regional functions showed dynamic and complex characteristics,which can be divided into four paths:functional integration development,dominant function leading development,dual function coordinated promotion development,and multi-function comprehensive development.
