Research On The Vertical Design Of Urban Park Green Space Based On LID

At the same time,rain flood brings negative effects to human and ecological environment.If it can be managed and utilized in a reasonable and scientific way,it can also become a natural resource and bring benefits to urban ecological living environment.From the perspective of storm water management measures,urban park green space is an effective way to collect storm water resources.The concept of lowimpact development(LID),as a booming stormwater management measure in recent years,cannot be implemented without the assistance of various urban green Spaces.The low impact development kit contains a number of measures.Taking theLiulige ruins parkas an example,this paper analyzes the flood control characteristics of urban park green space under different micro-terrain conditions,and explores a set of terrain design forms of park green space landscape based on the theory of low-impact development,so as to improve the functions of urban park in flood management with scientific and systematic methods and enhance the flood control and storage capacity of the city.Through literature research,case study,model data analysis and other research methods,this paper will carry out research on domestic and foreign low-impact development,urban park terrain design,storm flood management and other theories.Rhino established the land model,and carried out elevation analysis,rainwater runoff analysis and slope analysis on the land.Rainwater runoff analysis was carried out with SWMM model and the analysis results were compared.By analyzing the cases of LID measures and vertical design in relevant urban parks at home and abroad,we can draw on the successful experience of landscape design and help guide the research of the subject.Will eventually theory is applied to the actual,henan xinxiang huixian glass pavilion park two typical catchment area as the research object,the rainwater runoff under different vertical transformation,to simulate the case to verify the influence of different terrain of storm runoff and water saving,further prove the feasibility of this LID concept combined with city park.This paper relates to the vertical design of liulige ruins park in henan province.Through the study,the following conclusions were reached:(1)low-impact development(LID),as a natural,landscaped and low-cost urban stormwater management method,plays a significant role in managing stormwater runoff quantity and optimizing stormwater runoff quality.Based on this,this study proposed a method of urban park terrain planning and design based on the concept of low-impact development(LID).This method pays attention to the improvement of stormwater management in urban parks through topographic reconstruction,and takes stormwater recycling and urban stormwater runoff reduction as the goals of planning and design.(2)in the process of terrain reconstruction design,LID concept should be applied for rational configuration according to different planning and design requirements,so as to realize the regulation of rain and flood in urban parks.Compared with the traditional urban park green space planning and design,the landscape effect is more natural,the construction cost is lower,and the system function is more comprehensive.(3)through the simulation of the rain and flood management effect after the topographic reconstruction design of the case plot,it is preliminarily verified that the urban park green space after the topographic reconstruction design has the ability to reduce rainfall runoff and collect rainwater,and the methodology established in this study is preliminarily tested.It indicates that the design method of urban park terrain reconstruction based on the concept of low-impact development(LID)is feasible and has certain demonstration significance for other park planning and design projects.
