Research On Urban Road Green Landscape Design Based On LID

With the acceleration of urbanization process,impervious area of impermeable,making the city's water cycle system has been affected,when the occurrence of heavy rainfall,most of the city there have been waterlogging and other rain problems.How to do rainwater in different stages of the use of ease,how to use the rain to become the current city of China is facing an important issue.Urban road is the city's framework,lifeline,but also the core of the city landscape and image.The city's political,economic,commercial and other activities and people's lives are closely related to urban roads.The road as a total area of urban land 8%-15% of the land use system,rainwater runoff,rainwater pollution occurs mainly in road land,agglomeration and emissions,and because the city road network and has a longitudinal slope,cross slope characteristics of the site,making It is of great significance to explore how to design the rainwater adaptability of urban road green landscapes and to create the ecological environment of urban green space.In this paper,the concept of low impact development(LID)into the road green landscape design,with a view to China's road green building to provide an ecological,efficient and beautiful application.This paper first combs and summarizes the theories of low impact development(LID)theory and urban road green landscape,and combines with the excellent practice cases of applying LID concept in urban road green space,which provides theoretical basis and case reference for the following development.Secondly,through the comprehensive comparison of the domestic cities,the first batch of "sponge city" construction pilot cities Zhenjiang,Jiaxing and the earlier application of LID city Shanghai as the research object,through the field survey,the three cities in the use of LID The status of the road green landscape,including the type of LID facilities and the location of the application,the type and configuration of the plant,the type of pavement,the status of conservation management,etc.,summed up the existing problems:green form is simple,improper plant selection,LID facilities The application of a single type,inadequate maintenance and other issues.Then,based on the research and analysis,the paper puts forward the principle of urban road green space landscape design based on LID,and selects the LID facility suitable for urban road green space through the comparison of economic and technological development with low impact,and summarizes the functional characteristics and application of each technology Condition,and summarizes the specific methods of LID-based road green belt,parking lot green space,square green space and traffic island green space landscape design and the basic requirements of plant selection and the types of plants in LID facilities.Finally,the urban green landscape design method based on low impact development(LID)is presented in this paper,and the LID technology is used to show the results of various LID technologies.Design project has a certain demonstration significance.
