Research On Near-natural Landscape Architecture Of Urban River

The relationship between the city and the river is from the city to the river to the city to build the river,the river space is squeezed,the river channel is rerouted,buried,the river bank is channelized,and the natural river channel becomes a gray drainage ditch.This series of engineering construction has brought short-term economic benefits,while river ecological problems have gradually been exposed.River atrophy,water blockage,water pollution,floodplain vegetation degradation,reduction of aquatic species,decline of river habitat diversity and spatial heterogeneity,frequent flooding,and reduction of groundwater replenishment and other river ecological problems.Urban rain and flood safety issues.Compared with traditional river remediation projects,the near-natural river remediation project is a method that essentially considers the natural attributes of the river,respects the law of natural evolution of the river,and restores the health of the river.This article starts with the development history of near-natural governance,domestic and foreign near-natural river governance concepts and technical experience,river structure and natural attributes,and analyzes the related concepts of urban river near-naturalness,and sorts out the relationship between urban development and river evolution.It focuses on summarizing the design principles,strategies,procedures,and restoration methods and techniques of different levels of rivers in the city near natural landscape.Finally,a comprehensive analysis of excellent cases,summarizes the bank slope protection technology and river habitat restoration methods,theoretically summarizes the methods and strategies suitable for the restoration and design of urban rivers near natural landscapes,and uses the Yongxing River in Beijing’s Airport Economic Zone Take the park design as an example,focusing on the use of the urban river near-natural landscape design governance concept and ecological bank protection technology studied in this article to carry out river restoration and landscape design on the Yongxing River,covering river habitat restoration,river biological protection,river area population use,and urban The improvement of green infrastructure and sponge construction,etc.,in order to realize the sustainable and healthy development of cities and rivers.
