Research On The Identification And Planning Strategy Of Inefficient Land Use In Xuanhua Historical And Cultural City

With the acceleration of urbanization,urbanization entered the stage of high quality development,the early stage of the urbanization in pursuit of speed,the extension of the city disorder and expansion,leading to the contradiction between supply and demand of land,in order to solve the urbanization in the particular stage of disorderly expansion,stock planning era arises at the historic moment,and the stock of urban land tapping object focus for the low utility of land.The party’s 20 th annual report mentioned that we should implement a comprehensive conservation strategy and promote the economical and intensive use of all kinds of resources.The redevelopment of low-efficiency land plays an important role in improving urban function and improving urban quality in urban construction.Therefore,it is particularly important to identify the inefficient urban land and put forward the corresponding redevelopment strategies for the identified inefficient land plots.Both internationally and internally,they attach great importance to the protection of history and culture.The historical and cultural work of cities around the world is constantly developing and advancing,and the protection mechanism is improving day by day.Internationally,a consensus has been reached on the protection of famous historical and cultural cities,to explore their cultural value and revitalize them.But at present,many cities in China look very similar,it can be said that thousands of cities,the city lack of characteristics,lack of competitiveness.In order to enhance the core competitiveness of a city,it is necessary to explore the characteristics and make good use of the resources of the city,especially the historical and cultural resources.Based on the above background,combing the relationship between the historical and cultural city protection and inefficient land identification,consider belongs to the historical and cultural city,under the influence of the protection of the identification of inefficient work should be how,through the literature review,field investigation,big data analysis method,the identification method of historical and cultural city city inefficient land systematic research.first,Identify inefficient land in towns without considering the influence of famous historical and cultural cities,By dividing the influence scope of famous historical and cultural cities into three levels: historical city,historical and cultural blocks and other historical areas,cultural relics protection units and historical buildings,Establish the evaluation index system for these three levels respectively,sequentially identify the inefficient land obtained under the influence of these ranges,The inefficient land plots identified multiple times were superimposed,Based on the inefficient plots identified without considering the influence of famous historical and cultural cities,Increase the inefficient plots that affect the protection of famous historical and cultural cities,At the same time,the plots within the core protection scope of the historical and cultural city will be deleted,The final result of inefficient land identification of historical and cultural famous cities is obtained.Taking xuanhua city as an example,the identification method of inefficient land in famous historical and cultural cities is studied effectively.For historical and cultural city protection planning,put forward the low utility of redevelopment planning strategy,using xuanhua city specific plot of the historical and cultural city inefficient redevelopment planning strategy in detail,expectations for other historical and cultural city of inefficient land identification method to provide systematic reference,provide theoretical guidance for its redevelopment planning.
