Research On Landscape Design Of Urban Watercourse Supplemented By Reclaimed Water From The Perspective Of Ecological Restoration

With the development of urbanization,urban water problems in our country have become increasingly prominent.Water shortages and water pollution have intensified.As an important ecological and landscape corridor of the city,the ecological problems faced by rivers are becoming more and mo re serious,especially in northern China.In urban areas,the amount of natural precipitation cannot meet the ecological water demand of the river,which has become a major problem in the construction of urban landscapes.Therefore,the reuse of reclaimed water for urban river landscape construction has become an effective way to alleviate urban water problems.However,its special recharge water source has certain limitations and requires restoration and maintenance of the water environment.In this paper,based on the actual needs of the ecological restoration of the river water supply in urban water supply,based on the theoretical analysis of ecological restoration,the urban river landscape design is reconsidered.Based on the theory of ecological restoration,this paper discusses the landscape restoration design strategy for urban water supply in combination with the restoration project of the Xushuihe River in Zhengzhou,in order to provide new ideas for the construction of river landscapes in water-scarce cities.The mitigation and urban ecological civilization construction play an active role.This article takes issue-oriented analysis and research and follows the idea of "problem problem-analysis problem-solve problem-practical application".The main contents can be summarized as the following four points: The first part consists of the first chapter and the second chapter.For questions.It mainly elaborates on the source,research background,significance and methods of the project,and defines related concepts such as urban river landscape and recharged rivers,and analyzes their limitations and problems.The second part is the third chapter.problem.Based on the issues summarized in the previous section,the relevant theories of ecological restoration were introduced and their main points were combed.Combined with the classic cases at home and abroad,the feasibility of the application of the ecological restoration theory in the landscape design of urban water supply urban rivers was clearly analyzed.The third part is the fourth chapter,to solve the problem.Through the research on the relationship between the theory of ecological restoration and landscape design of urban water supply,the idea of water supply urban river design based on ecolo gical restoration theory is summarized,and the specific design strategy is summarized;the fourth part is from the The five chapters and the sixth chapter,combined with the Zhengshui Xushui river Landscape Restoration Design Practice Project,detailed analysis and verification of the specific design strategy,determine the feasibility of this strategy,and summarize the main results of the paper and the deficiencies.
