Landscape Design Of Junxi River In Datian County Based On Ecological Restoration Concept

In the process of rapid economic and social development,problems such as the indiscriminate encroachment of the biological habitat on both sides of the river by the construction land,the discharge of life and industrial and agricultural pollution into the river,the imperfect river planning and protection policies,etc.,have caused serious problems in the river ecosystem and the loss of landscape recreation.In recent years,with the continuous strengthening of water ecological civilization construction,people have gradually realized the importance of river ecological environment,and more and more experts and scholars have invested in the research and practice of river ecosystem restoration.This paper first summarized the current domestic and international research progress of river ecological restoration,then the relevant theories and research methods of river ecological restoration were briefly described.Further,this paper briefly summarized the characteristics of urban river landscape and rural river landscape and the principles and methods for landscape design of urban rural rivers under the theory of river ecological restoration.A set of systematic strategies and methods,which is guided by ecological restoration concept,starred from the professional perspective of landscape architecture,and combined with landscape ecology,hydrology and other subject knowledge and related water conservancy and hydraulics,were formed after analyzing and summarizing the classic river ecological restoration cases at home and abroad.The technology and methods of the river ecological restoration and landscape design were further summarized and applied in the ecological restoration landscape design of the Junxi River in Datian County.The project was located in Junxi river,Datian County,Sanming City.It mainly designed ecological restoration landscapes for the watercourse and the river buffer zones on both banks.The design was guided by the concept of ecological restoration,and combined with multi-scale analysis methods: firstly,the current ecological status of Junxi was analyzed and divided into three parts,namely the water source ecological conservation section,waterfront ecological restorations section and rural ecological restoration section,according to its own conditions,characteristics and external environment.Further aiming at the differences in the nature,hydrological topography and ecological conditions of the surrounding river sections and urban river sections,the river landscape ecological restoration strategy was used to solve the contradiction between ecological environment,production and life,and landscape construction.Finally,through the special design of plant layout landscape design,river ecological slope protection design and soil buffer belt restoration design for each river section,the ecological restoration landscape design of the Junxi river was improved,so as to better realize the ecological landscape reconstruction of Junxi river.
