Sustainable Reconstruction Of Urban Waterscape Space Showed By Shenyang Huishan Open Channel

In recent years,due to the concurrence between the scarcity of water resources and the frequent occurrence of urban flood disasters,the urban problems are concurred and intensified.People are beginning to realize the importance of ecological restoration of urban water cycle.A series of research on sponge city began to pay more attention to rainwater management,comprehensive utilization of water resources,landscape construction of infrastructure and so on,which can be used as an entry point for disciplines in terms of landscape,municipal administration,planning and ecology.Sponge city research and practice.This article takes Huishan open channel as the research object and explores how the typical municipal infrastructure enhances the landscape ecological effect in the urban area where the reconstruction is carried out from the perspective of the sponge city and puts forward the measures and methods for landscape reconstruction aimed at restoring the ecological benefits of the urban traditional infrastructure,Improve the sponge city in this area to implement the feasibility.According to the introduction of Huishan open channel landscape reconstruction process research,finding the problem and analyzing the cause of the problem,as well as the settlement of the strategy and the refinement of measures,can be divided into three parts.First of all,based on field survey,literature synthesis and interdisciplinary research methods,this dissertation starts from the municipal and landscape disciplines and reviews a large number of domestic and foreign literature related to infrastructure landscape and green infrastructure construction.,This paper analyzes the concept,the shape of the open channel,the flow pattern,the detailed analysis of the basic knowledge of hydraulics,and the successful case analysis of relevant theories at home and abroad.It analyzes the overall nature of Huishan Open Channel and analyzes the current situation,Purpose and significance of the research,define the research scope of open channel,summarize the three main problems that the status quo of the open channel is scattered,such as the lack of holistic thinking,the obsolete facilities without ecological effect,and the negative utilization of space without recreation.On the one hand,by analyzing the related concept and theory of rainwater utilization and low-impact development,the relationship between the two and the research progress and outstanding cases both at home and abroad,this paper analyzes the nature of Huishan open channel and analyzes the status quo.sort.Afterwards,based on the above problems,the author calculated the runoff of the open channel in detail and carried out a quantitative assessment of the displacement and the carrying capacity of rainwater in Huishan Open Channel.In view of the availability of the rainwater landscape along the open channel,After defining the relevant parameters of Huishan Open Channel,the SWMM model was analyzed and simulated,and the peak flow of runoff at different recurring periods was obtained.Based on the analysis of the constraints,principles and technical routes,The data put forward the optimization strategy of Huishan open channel and carried out the overall structure of the rainwater ecosystem on both sides of the open channel.According to the regional characteristics of North China from the macroscopic level,the source collecting subsystem,middle seepage subsystem and terminal runner System construction of three facilities,taking into account the richness and complexity of landscape habitats created under the concept of sponge city,rainwater infrastructure adaptable to specific sections is screened for different sections of rainfall conditions so that the three systems The specific facilities in a reasonable series and parallel,synergy between each other,and the use of specific channels of funding Expand the available landscape space for the recreation of surrounding residents and restore the open space around open nullahs so as to increase the flood control potential of open ditches and enhance the safety and stability around the open channel of flood season.At the end of the study,the paper compares the proposed landscape improvement planning strategies with the integrated landscape benefits and concludes that the improvement measures of rainflies assisted by the scenic spots around the open channels can effectively reduce the rainfall,which increases the open channel’s rainwater in the present urban environment Recycling ecology,and enhance the utilization of landscape around the open channel.At the end of the article,the author discusses the shortcomings of this paper and the related extension direction,and provides a new idea for landscape reconstruction of the same type of municipal infrastructure.
