Planning And Design Of Gejia Lake Ecological Park In Changde City

As an important part of urban green space system,urban ecological park plays an important role in improving human settlements and urban environment,and has various functions such as adjusting regional microclimate,improving air quality,and maintaining urban ecological balance.However,the space along the elevated track is often a narrow strip of green space,which has a potential ecological corridor role,and also has a good link relationship with the urban internal traffic function.The introduction of urban ecological parks is providing it with appropriate key elements that can stimulate vitality,which is an important support for the sustainable development of the site,and exploring the theoretical support and realization approach for the integrated development of the elevated track and ecological parks,Try to excavate more relevance value from the perspective of system and build a park ecosystem that can maintain long-term stability.Taking the ecological park along the elevated line as the research object and the design of Gejia Lake ecological park as the practice object,this paper discusses how to carry out the landscape design of urban ecological parks along the elevated line by using the methods of literature analysis,case analysis,questionnaire survey and inductive analysis,and achieves the following results:(1)Carry out a preliminary study on the relevant theories of the design of ecological parks along the elevated line,and summarize five theoretical bases with high applicability,namely,the theory of landscape ecology,the theory of urban catalyst,the theory of landscape perception,the theory of sustainability and the theory of place context,which lays a theoretical foundation for the design methods and design models of ecological parks along the elevated line from the perspectives of ecology,function,human perception,culture,etc.(2)Combining the ecological park and the space along the elevated line,five excellent practical cases are selected:Changsha Guitang River Ecological Park,Changchun Water Culture Ecological Park,Barcelona Trinidad Park and Chengdu Guixi Ecological Park.It analyzes its advantages from the project overview,design features and experience,and provides inspiration for the design methods of the ecological park in terms of terrain design,water system planning,functional division,cultural excavation,as well as the crowd demand,traffic design,vertical design and other aspects of the space along the elevated line.(3)This paper combs the morphological classification and characteristics of the space along the elevated line,further obtains the connotation and characteristics of the ecological park along the elevated line,summarizes the corresponding design principles,and finally proposes the design model from the four aspects of environmental perceived safety,ecological sustainability,traffic accessibility and context continuity,providing theoretical guidance for the design of Gejia Lake Ecological Park.(4)Taking Gejia Lake Ecological Park as the design practice,the upper planning interpretation is carried out,the existing problems and corresponding strategies are clarified through the site status survey and analysis,the design objectives and positioning of the site are clarified,and the design concept and theme are proposed.Through the restoration and extension of land and water habitats on the site,the roaming trails are connected in series to activate the upgrading function,and the space along the elevated line is built into a highquality ecological corridor.The historical context is integrated into the design,and the site memory is preserved,so that the Gejia Lake Ecological Park will become a characteristic urban space worthy of preservation and memory while meeting the needs of citizens’ ecological experience,popular science education,sports and leisure,and cultural heritage.
