Research Of The Application Of Ecological Remediation Theory In Eco-corridor Of Urban Rver Landscape Design

As the birthplace of human civilization,river carries the function of landscape in the city,provids water for the whole ecosystem and beautiful scenery for people.With the river was constantly polluted,eco-corridor of urban rver suffered great damage and the river landscape zone needs repair.Countries pay more and more attention to the restoration of river corridor and the ascension of landscape,and puts forward "urban double fix" governance.Policies pay more attention to the restoration of urban river system and river corridor.Based on landscape ecology,the concept of ecological restoration and related researches,as well as the analysis of outstanding cases,putting forward the design principle of urban river ecological corridor under the current social background.The design of the planar layout of the urban river ecological corridor mainly including road,rigid space layout and form,roads and rigid spatial distribution directly determines the "people" the biological factor's influence on the ecosystem.Therefore different functional partition,the layout is different.According to the theory of ecological restoration,combined with the specific ecological restoration measures,designing landscape facilities,landscape sketch that has ecological and aesthetic value.The survey found that the river ecological corridor is a part of the city,bearing the weight of the humanistic spirit of city and important ecological service function.So in the designing process,in terms of graphic expression,the landscape should be combined with urban texture at the junction of the river landscape corridor and cities;In terms of ecological system,due to fringe effect is more remarkable in the junction of the edge,designing the rich activity space and maintaining ecosystem stability,optimizing urban landscape;In terms of humanities,Combining the city's cultural spirit,the connotation of the place with the design of landscape space,such as landscape sketch,the setting of folk activities.Finally,based on the research,from the vertical and horizontal,vertical,time,multi-dimensional perspective of ecological corridor of Caohe,building a landscape corridor demonstration section combining leisure,ecology,and education and with the ecological concept as a guide for the core.
