Research On Landscape Design Strategy Of Baicheng City Road Based On Low Impact Development

The rapid urbanization process makes the proportion of impervious roads in the area of urban areas growing,which brought negative impact on city's ecological environment.With the increasingly serious problem of urban road rainwater management in China,it is urgent to design urban road which meet the road function and solve the problem of raindrop.Therefore,it is necessary to construct low-impact development of landscape road system,in order to solve the problem of urban road rainwater.First of all,this study reviews the research of a large number of low-impact development and landscape road planning at home and abroad,in terms with connotation,development,goals and principles of low impact development.Relevant basic theory of low impact development and the urban landscape road theory are stated.Related success cases lay theoretical foundation for road landscape design based on LID(Low Impact Development).Secondly,the principle of road landscape design based on LID is analyzed,and the road design strategy based on LID is put forward,and the corresponding planning ideas and planning principles are put forward.By analyzing the location of Baicheng City,the present situation of Baicheng road landscape is summarized.It is suggested that the landscape structure of Baicheng City is not perfect,the pollution of water system is serious,the problem of road drainage,and the waste of water resources.In view of the problem,combined with the specific circumstances of Baicheng proposed road landscape design strategy and develop specific design.Plan to determine the Baicheng city of LID road landscape pilot range,the development of Baicheng city LID road landscape overall design.And on the basis of road landscape and ecological design,the design of low impact development technology is put forward.The layout and road connection design of LID facilities are carried out respectively for residential roads,sidewalks,motor vehicles,buffer green belts and parking lots.Road landscape green space system,history and culture,landscape style and plant design four aspects of detailed optimization design.Finally,it is necessary to evaluate the expected benefit analysis of LID landscape road program.It is proposed that LID landscape road construction will protect the urban ecological environment and enhance the ecological benefits of the city,provide a comfortable and safe living environment,effectively reduce urban non-point source pollution,improve runoff water quality,Resource security and other advantages.With a view to the use of LID concept to solve the current serious rain problems,and water pollution problems.
