Research On The Spatial Landscape Identification And Renewal Strategy Of "Production,Life And Ecology" Space In Famous Historical And Cultural Towns

In the long river of history,many famous towns with history and traditional humanities have been bred in China’s vast territory,enriching the types of historical and cultural heritage and achieving the most important material and spiritual wealth of our country.However,with the development of China’s economy,many changes have taken place in urban and rural construction,and many historical and cultural towns have been damaged to varying degrees.National government departments have gradually realized that famous historical and cultural towns have extremely valuable cultural resources.For the protection and healthy development of famous historical and cultural towns,they have successively issued a series of laws and regulations.Therefore,strengthening the protection of the spatial form of famous historical and cultural towns,scientifically and reasonably constructing the spatial layout and spatial structure,and constantly updating the "Production,Life and Ecology" spatial landscape pattern are important measures to realize the protection of famous historical and cultural towns and the healthy development of the "Production,Life and Ecology" spatial landscape.In this context,this paper takes Xucun Town,a famous historical and cultural town in the mountainous and hilly area of Southern Anhui as the research object,and adopts the research methods of literature analysis and field investigation,remote sensing geographic information system analysis,landscape pattern analysis,quantitative and qualitative combination,so as to integrate the spatial related theory of“Production,Life and Ecology” into the protection and renewal of famous historical and cultural towns,Construction of a famous historical and cultural town--Research and Practice on the identification and renewal method of spatial landscape in Xucun town.The research results show that there are differences in the spatial landscape distribution of the “Production,Life and Ecology” in Xucun Town,a famous historical and cultural town and the development level of each village.In general,Xucun Town presents empty and fragmented living space,streets,lanes,historical buildings and other landscapes.Dilapidated,low-efficiency production space functions,and ecological space landscape functions are not effectively reflected.Therefore,it can provide a reasonable basis for the “Production,Life and Ecology”space landscape renewal strategy.The main results of this research are as follows: 1)The relevant literature on the study of the “Production,Life and Ecology” space and the conservation of historical and cultural towns at home and abroad is analysed and summarised,and the concepts of the “Production,Life and Ecology” space and historical and cultural towns are clearly defined.Subsequently,the method of identifying and classifying the “Production,Life and Ecology” space at different scales of the study area is summarised,and the analysis of their layout characteristics and comprehensive optimisation strategies are drawn up to establish the ideas of the study of the "“Production,Life and Ecology” space in the study area in this paper.2)Based on the land use data in 2020 combined with Landsat-8 OLI＿TIRS remote sensing images,using ARC GIS 10.8,ENVI 5.3 and other software to identify and divide the "three-life" space of Xucun Town,and then analyze its landscape pattern index by Fragstats4.The spatial distribution of “Production,Life and Ecology” in villages and towns is uneven,the landscape patches are obviously differentiated,and the space is fragmented.The main performance characteristics are that the production space is dominated by traditional agriculture,the living space is agglomeration of villages with uneven distribution and high hollowing rate,and the ecological space is a good degree of vegetation coverage.At the same time,there are compatibility and contradictory relationships in the overall pattern of the “Production,Life and Ecology” space.3)From the analysis of the current situation of the living space,production space,ecological space and landscape function of the landscape elements of water bodies,buildings,roads and greening systems in Xu Cun Town,it is concluded that although the tourism resources of Xu Cun Town are rich,they have not been fully developed;the developed landscape has not been protected at the same time,and the tourism resources are not fully developed.4)According to the analysis results,an update strategy is proposed.From a macro perspective,this paper puts forward the guidance strategy of spatial pattern,so as to re divide the whole landscape of Xucun town into "one core and multi regional landscape".The northern part of the town is the happy living and healthy area of the mountain,the town is the core area of the whole tourism,the central and western part is the platform sightseeing and leisure area,the southwest part of the town is the rural scenery experience area,and the southern part of the town is the local humanistic nourishment area.From the middle and micro level,take rural tourism as the main idea,improve the living space,improve the infrastructure,reasonably layout the village pattern,and scientifically and reasonably build a beautiful rural living environment;Production space,reasonably plan the distribution of farmland,forest land,villages and other elements,deeply dig and strengthen industrial development,and form a variety of industrial forms such as tea and fruit Township sightseeing,agricultural experience and catering services to expand the channels for farmers to increase their income;In terms of ecological space,maintain the original river form and ecological base,implement corresponding restoration and regulation according to the actual situation,expand the conversion of farmland to forest and grassland,and build a famous historical and cultural town with stable and healthy ecosystem.
