Research On Site Conservation Zoning Of Unban Fringe Area

The site occupies a prominent position in the composition of China's historical and cultural heritage with rich historical heritage and cultural connotation.With the rapid advancement of urbanization in China,the contradiction between site protection and regional social and economic development is becoming more and more difficult to coordinate,and site protection is also facing serious challenges.The key to site protection planning is the protection zone,which is an important part to realize the comprehensive and overall protection of the site.At the current stage,most of the site protection zones in China have problems of lack of flexibility,poor operability and difficulty to coordinate with other social development plans in the region.With the overall development of urban and rural construction and the systematic development of cultural relics protection,the existing protection zones has been unable to meet the requirements of site protection,and it is urgent to conduct a deeper discussion on the methods of protection zonesThe research content of this paper is mainly composed of three parts.The first part is the basic research.Firstly,it sorts out the site's current status of the urban fringe area.It points out the positive significance of protecting heritage of the fringe area from the four dimensions of space,ecology,culture and society,listing destructive factors and influences of sites in the fringe area.The second part is the core of the technical theory of this paper.It summarizes the limitations of common methods and methods of protection zoning.Through the above content,it has a basic understanding of the site protection of urban fringe area,and then put forward protection method based on ecological sensitivity evaluation,discusses the selection of ecological factors and the calculation of weights in the site protection zoning,and proposes corresponding protection strategies.The third part is the practice of the protection and division of the Shenziguo site in Anhui Province,including sufficient basic data research,and then the paper uses the GIS platform to conduct detailed ecological sensitivity research and analysis of the study area,determines the protection zone,and proposes corresponding protection management regulations on the basis of the analysis results.The main results of the research are:the pattern of the Shenziguo site in Anhui Province;combined with the results of the basic research,the ecological sensitivity of Shen Ziguo is analyzed and the corresponding distribution map of each influencing factor is obtained;the weighted superposition method is used to analyze the factor comprehensive ecological sensitivity.The ecological sensitivity of the regional division is divided into extremely high,high,medium,low and insensitive area;based on the results of ecological sensitivity assessment,the protection scope,the construction control zone,and the environmental coordination zone are determined,and corresponding classification protection measures are raised.
