Research On Ecosystem Services Supply And Demand Evaluation And Landscape Optimization Of Urban Waterfront In Panlong River

Urban waterfront space has been studied for many years,and it needs to be optimized in the period of stock development,which is an important link of ecological civilization construction.Panlong River is the most important river in Kunming,and the largest flow into Dianchi Lake.In recent years,Kunming has made sustained and comprehensive efforts to improve the water quality and riparian landscape of Panlong River,and has achieved remarkable results,however,there are still some problems such as the dislocation of the function of landscape ecological space and the lack of prominent landscape characteristics.Through literature research and fieldwork,starting from the theory of ecosystem service supply and demand,the waterfront space in the central urban area of Panlong River is divided into 28 research units,and an ecosystem service supply and demand evaluation system is constructed,and the research units are weighted and evaluated,and the assessment results are compared and fitted.Through the spatial matching results of supply and demand,this thesis tries to identify the research units with misaligned functions of the Panlong River waterfront space ecosystem,summarize their existing problems,and propose targeted optimization and improvement strategies for the refined design of their landscapes.Through the above research,three typical waterfront space research units were selected for landscape optimization design,and the results of the assessment of ecosystem service supply and demand were tried to be implemented through practical projects.This thesis provides a design method with the design goal of satisfying ecosystem demand services,showing that the theory of ecosystem service supply and demand can be used as a guiding basis for site-scale landscape design projects,and provide a reference for the ecological practice of waterfront space.
