Research On River Restoration Design Led By Natural Process

In view of the increasingly serious water pollution and water resources shortage and other environmental problems,the restoration of the natural ecology of rivers has long been put on the agenda.As an important part of the urban ecosystem,the river corridor formed by the combination of the river channel and the surrounding green space plays an important role in the urban ecosystem and is also an important factor for the formation of unique urban features.In order to solve the increasingly prominent contradiction between human and rivers,the traditional river management works mostly use engineering technology to solve,which destroys the connection between rivers and nature,and pays less attention to the impact of natural processes on rivers.Therefore,it is imperative for us to make full use of the natural process to build a harmonious urban water corridor.Through literature review,theoretical research and case analysis,this paper studies related theories and case practices of river restoration under natural concepts at home and abroad,and obtains ecological restoration strategies under the guidance of natural processes.Through computer simulation analysis and empirical research,this paper studies the southern water system of Nanpi County,Cangzhou city,Hebei Province,carries out the planning and design of river ecological restoration,and puts forward specific measures to adapt to the local natural process.The main innovation point of this paper is to take the river course restoration dominated by natural process as the theoretical basis for the design method of urban river course restoration.From the perspective of natural process leading urban river design,it is emphasized to build a sustainable and low-maintenance river landscape by landscape means and through appropriate human intervention.In the study of river landscape design,MIKE21 was used for the first time to objectively and scientifically analyze the current situation of river and guide the subsequent landscape design in combination with water conservancy engineering software for the design strategy.Through the landscape design of Nanpi county south city water system,it provides different reference perspectives and reference significance for the future urban river landscape restoration design.
