Spatial evolution,influencing factors,and governance paths of megacity fringe areas:Taking Baiyun District of Guangzhou City as an example
The periphery of megacities is the frontier area of urban spatial expansion and extension,and it is an important area where the modernization of governance system and governance capacity is urgently needed.Taking Baiyun District of Guangzhou City as an example,this study analyzed the process,characteristics,influencing factors,and driving mechanism of land use change and urban spatial evolution in the district from 1985 to 2020 by using FROM-GLC10 LULC data products,land use transfer matrix,grey correlation analysis,and GIS spatial analysis methods.On this basis,the article discussed the governance path and model of megacity fringe area.The results show that:1)From 1985 to 2020,the land use change in Baiyun District was significant,and the characteristics of land use change were mainly the rapid growth of construction land and the decrease of cultivated land,forest land,and grassland.2)During the study period,the construction land change in Baiyun District experienced four stages:Sudden rapid expansion,high-speed and stable expansion,slowing expansion,and low-speed expansion.The expansion of construction land was significantly affected by the radiation of the central urban area,showing a spatial trend of expansion from south to north.3)The spatial evolution of the megacity fringe area is affected by natural factors,geographical location,economic development,factor input,policy system,and other factors,and a variety of factors jointly drive the land use change and spatial evolution of the megacity fringe area.4)In the future,the governance of the periphery of China's megacities should focus on innovating the concept of governance,improving the content and objectives,innovating the means and models,and improving the system and mechanism,so as to effectively promote the modernization of the governance system and governance capacity,and realize urban-rural co-governance,pluralistic co-governance,overall intelligent governance,and grassroots autonomy.The research results can provide a theoretical reference and practical guidance for urban planning,construction,and modern governance in China in the new era.
