Research On The Spatial Expansion Of Historical And Cultural Villages And Towns Under The Protection-development Scenario

With the acceleration of China’s urbanization process,it has brought huge impacts on the economic development,population flow,and land space construction of the vast villages and towns.It has also caused a series of problems such as the deterioration of the ecological environment and the decline of the physical environment of remote villages and towns."Frequent phenomena.Among them,historical and cultural villages and towns,as a special type of villages and towns,not only have the functions of ensuring food security and providing ecological barriers,but also have the functions of inheriting historical culture that are not available in ordinary villages and towns.Taking into account the particularities of historical and cultural villages and towns,it is not enough to protect historical culture from the aspects of restoration of architectural relics and the coordination of landscape features.We should strengthen our thinking on how to protect historical culture in land use control and spatial organization,so as to make villages and towns sustainable economically.Development and space expansion are important manifestations of the rural revitalization program.This article takes Wanling Ancient Town as the research object.It is based on the trend that the number and scale of villages and towns are generally shrinking.Wanling Ancient Town continues to expand and the old streets are well preserved.It has a typical sample significance for studying the space construction of historical and cultural villages.Combining satellite maps,field survey data,relevant statistical data,etc.,the spatial evolution of Wanling Ancient Town and the spatial characteristics of villages and towns in various historical periods are sorted out.From the summary of the space-time regularity of the expansion of Wanling Ancient Town,historical protection is recognized in the historical evolution of space Play a decisive leading role.The protection of historical space promotes the development of tourism and the recommendation of town construction in Wanling ancient town,and then drives the outward expansion of village and town space.Based on this recognition,this paper summarizes the spatial expansion mechanism of Wanling ancient town under the protection and development by combining qualitative and quantitative methods according to the thought of "protection development scenario practice of main body behavior activity results of spatial expansion" It is mainly affected by the historical environment,government decision-making,tourism industry and social structure.In addition,this paper predicts the future spatial evolution results of Wanling ancient town with the help of GIS spatial analysis,CLUE-S model and other quantitative research.Combined with the practical problems,it puts forward the spatial development strategies for historical environment protection of Wanling ancient town,and forecasts the spatial expansion results under the protection development scenario through quantitative research again.The paper studies and analyzes the spatial form and scale comparison under the two scenarios,and finally summarizes the evolution trend and spatial development direction of the spatial expansion of Wanling ancient town in the future,so as to find a scientific management and control basis for the spatial planning and development and construction of Wanling ancient town in the future.
