Research On Sustainable Landscape Design Of Urban City Center Green Space Renewal In Changsha Under The Stock Planning

In recent years,the rapid development and progress of economic society has driven the rapid development and expansion of urban construction.The incremental bottleneck brought by rapid urban development has led to the direction of urban planning gradually shifting from incremental to stock.Stock planning is the general trend of the current era.It is also the "new normal" for future urban development and construction.Urban renewal is implemented as a means of stock planning.Major cities have launched urban renewal campaigns.Green spaces in urban centers,as important stock space resources of cities,are playing an important role in the process of urban renewal.As the capital city of Hunan Province,Changsha is also an important central city in the middle reaches of the Yangtze River.Known as a famous historical and cultural city,it has been continuously rated as one of the "Happiest City in China",which is inseparable from the benefits of Changsha’s urban green space.Therefore,this article will take Changsha City as an example to conduct in-depth research on the renewal design of urban green space.The research content is as follows:First of all,analyze and sort out the research dynamics of urban center green space renewal at home and abroad,summarize the good experience of related foreign studies and the problems and deficiencies of domesticurban center green space,and provide empirical references and solutions for the research.Secondly,clarify the definitions and concepts related to the sustainable planning of the existing landscape planning and put forward the necessity of sustainable landscape design under the existing planning.Thirdly,through the field investigation of Changsha city center green space,sort out the current situation and existing problems of Changsha city center green space,summarize the sustainable design principles of Changsha city center green space renewal under the stock plan,and from the three levels of planning,design and technology The in-depth analysis of the green space renewal design of Changsha City Center.Finally,the analysis design method is applied to the Changsha Wuyi Square renovation project to verify the implementation effect of the theoretical results in specific projects.The article summarizes the design principles,strategies,and methods of urban green space renewal by analyzing and researching the current situation of Changsha’s urban green space,and is committed to solving the problems that will occur in the future urban green space renewal in Changsha.The design concept is the guide to form a multi-faceted and multi-level urban green space renewal design method,which is instructive in practice and contributes to the sustainable development of Changsha’s urban green space.
