Restoration Of The New River Side Landscape In Jiaozuo City Based On Ecological Concept

Rivers are important natural historical heritages and ecological functions.As an important part of human settlements,urban rivers play an irreplaceable role.However,with the acceleration of urbanization process,urban rivers are generally damaged and threatened by human influence.Ecological restoration design of rivers is an inevi Tab.requirement of the development of The Times.Whether a river is healthy or not can even affect the development of a city,and the development of a city will eventually be reflected in the city river.How to coordinate the relationship between the city and the river and make scientific and reasonable planning is what the society needs to think about today.This paper combed the related concepts of river ecological restoration and research progress at home and abroad,on the basis of summarizing predecessors’ research of theory combined with the four practical cases,it is concluded that urban river ecological restoration should start from five aspects: the water ecological conservation and restoration,channel structure and form structure,river structure and morphology construction,slope ecological construction,the construction of biological habitat and waterfront activities in five aspects.Taking the Xinhe river in Jiaozuo city as the research object,the following problems of Xinhe river were proposed on the basis of full investigation into the current situation:less water,the basic ecological flow is difficult to maintain;poor water quality and serious river pollution;ecological function degradation,the ecological environment along the river is monotonous;hydrophilic poor,people and water is not closely linked,the lack of waterfront landscape and cultural connotation;flood control standard is low,flood discharge capacity is insufficient.Based on the existing problems,combined with the relevant theories and practical experience of ecological restoration,the ecological regulation method and landscape optimization approach of the corridor of xinhe river were discussed.After the overall planning and design of the new river,the detailed design of key nodes and key transformation types,as well as the special design of plant configuration,waterfront footpath,identification system and featured sketch,it is concluded that the restoration of the new riverside landscape should be carried out from the following aspects:(1)Through the river system,ensure the basic ecological flow of the river.(2)Artificial wetland construction,to enhance the basin flood storage and sewage purification capacity.(3)Embankment and revetment construction,the purpose is to enhance its flood control capacity and ecological benefits.(4)Ecological habitat construction,in order to increase biodiversity and restore the healthy development of river ecosystem.(5)Waterfront landscape and activity site construction,which can maintain the friendly contact between people and water.
