Research On Ecological Restoration And Landscape Design Of Urban Canalized Rivers Based On Water Purification

Since the 20th century,the problem of the destruction of the ecological environment of urban rivers and the single landscape environment has been widespread in the world.As an important carrier in urban space,culture and economic development,urban rivers have been concerned by the protection of ecosystems and the construction of ecological environment by experts in design,urban management and ecology.However,the facts show that in the past practice,the "technical" path based on ecological restoration engineering and the "art" path based on river gardening cannot effectively solve the problem of ecological restoration and landscape construction of urban channelized rivers.In this regard,the search for a landscape design path that is unified by technology and art needs to be considered and studied.This topic studies the ecological restoration and landscape design of urban channelized rivers through research methods such as literature research,case study and comprehensive research.Through the investigation of relevant theories and actual cases at home and abroad,this topic summarizes the general principles and implementation paths of urban river ecological restoration engineering and landscape design.Water purification is the key to research and practice.At the same time,this topic has carried out a detailed analysis of the design practice project of the Nanjing Pearl River ecological restoration landscape design.Specifically,the Nanjing Pearl River Design Practice Project focuses on water purification.First of all.through the analysis of the current situation and water quality research,the author proposes macro design goals and micro-quantitative design goals.Then,through the ecological engineering measures,the project will carry out macroscopic river reforl and preliminary water purification.and through the shoal(nmicro wetland")and ecological floating bed technology,the whole water purification of the river shallow water and deep water area will be carried out,and then the artificial floating island will be passed.The landscape construction forms such as spiral waterways and ecological ernbankments further purify the water quality,thereby completely purifying the water quality of the Pearl Ri7ver.Therefore,with a variety of ecological engineering leasures as the "functional" basis for purifying water quality,art design is used as a "fonn" means of the various elements of the river.After a period of "self-conditioning" of the Pearl River and later manual maintenance management,This design project can accomplish the design goals.Therefore,this research proposes a design method that combines ecological engineering measures with landscape design.
