Urban River Corridor Landscape Planning And Design Based On Ecosystem Service Theory

Urban riverside park is the most abundant place of urban natural landscape and historical and cultural landscape,and it is the business card that can best reflect the urban style.However,the rough and single development mode of the city leads to the rupture of the blue-green space structure of the urban waterfront and the crisis of the urban ecosystem,which leads to a series of problems such as the imbalance of the ecological water system and the lack of regional culture.As an important part of bluegreen space,urban river corridor plays an important role in the construction of urban blue-green space.The ecosystem service evaluation of urban river corridor is an important reference for river ecological restoration and urban waterfront planning.In this study,from the perspective of improving ecosystem services,taking urban river corridor as the starting point,an evaluation system of urban river corridor based on the theory of ecosystem services is constructed on the basis of systematic combing of relevant theories.Taking Shahe River Corridor in Huairou Science City as an example,the evaluation model guided by ecosystem services is established to evaluate urban river corridor,Find the pain point of the site,excavate the space value of the site,and further guide the planning strategy and design method of the waterfront park.This paper is divided into three parts: theoretical research,case analysis and empirical research.This research adopts the research framework of "research background-basic research and case analysis-Evaluation System Construction-evaluation result analysis-Design Strategy and method formulation-case demonstration".From the perspective of ecosystem service theory,through the investigation and research of the current resource conditions of the site,the resource evaluation of the site is carried out in the analysis process,and the Spatial Suitability layout is obtained,and the relevant cases are studied and analyzed,together with the guidance of planning and design strategies,to build a reasonable river corridor system and create a sustainable ecological landscape.In order to improve the service value of the ecosystem,this paper puts forward suggestions and guidance on the design strategies and methods for the construction of Urban Waterfront Park,and discusses respectively from three aspects of ecosystem security,cultural bearing and material supply.It mainly includes the planning strategies of optimizing the biological habitat,restoring the ecological base of the space,integrating the surrounding diverse space,expanding the recreational service function,preserving the site historical sites,translating the natural and cultural texture,and discussing the specific planning methods from the five aspects of ecological restoration,plant community,functional service,recreational facilities,and cultural translation.Driven by the active construction of blue-green space in Beijing,this paper takes Shahe Waterfront Park in Huairou Science City as an example to verify the rationality and operability of the research,and to provide scientific and reasonable technical support for the location,structural layout and planning strategy of the park.
