Research On Landscape Design Of Urban Waterfront Greenway Under The Concept Of "Sponge City"

With the continuous progress of urbanization in recent decades,many natural ecological Spaces around cities have been gradually swallowed up by the expansion of urban areas.Destroyed the original rapid urbanization and industrialization development of urban ecological system of natural balance with the natural hydrologic cycle,a large number of vegetation and green landscape been dug,replaced by skyscrapers and rigid pavement road surface,and industrial emissions causing serious pollution of city waters around,etc.,these man-made cities affected by heavy rains in China in recent years after the city waterlogging disasters,serious damage to people's travel safety and public caused incalculable social economic losses,the situation has caused the attention of the relevant departments in our country,the same as an environmental problem to be solved has aroused wide attention and research environment design practitioners.In the face of environmental degradation,people are increasingly eager to have green,open and natural ecological space in the city where they live.In order to gradually improve and solve the environmental problems,our country was proposed in 2012 by the "sponge city" concept,the concept follows the principle of ecological priority,on the premise of ensuring the security of the city drains,the natural approach combined with artificial measures,permeability,hysteresis,,net,use,storage,maximize the realization of rainwater in urban areas of stockpile,infiltration and purification,promoting rational utilization of rainwater resources and ecological environment protection.In concrete implementation,by the city of rivers and lakes constitute the main body framework "sponge" series not only the city area,green natural space,buildings and roads,such as system,also including subsided green space,the permeable pavement,planting grass and other urban drain facilities,and that of the urban waterfront aqua green way as the transition area between urban space and natural water environment,but also "sponge" connection of green land and waters,bearing permeable pavement road,arrangement ofcascade revetment of key areas.From the perspective of ecological environment design,this paper takes urban waterfront greenway landscape as the research object,and USES the concept of "sponge city" as the theoretical guidance to analyze the feasibility and necessity of the application of "sponge city" concept in urban waterfront greenway landscape design.This paper summarizes the concept of "sponge city" and the technical application parameters and related knowledge theories of urban waterfront greenway landscape design.Analyzed the urban waterfront greenway landscape design case under the concept of "sponge city";The landscape design method of urban waterfront greenway under the guidance of the concept of "sponge city" is summarized.And the author participated in the design of wuhan east lake greenway landscape design project as an example to demonstrate the practical application.The project to build a set of human activities,prevent waterlogging,water permeability,ecological restoration,cultural science combined with the storage in the integration of "sponge" urban water-front aqua green landscape,through the green channel design,permeable pavement materials,ecological wetland,ecological revetment configuration elements such as analysis,as the "city" sponge concept in urban waterfront aqua green road,landscape design and design the application to provide theoretical reference.
