Study On Urban Waterfront Landscape Design From The Perspective Of Sponge City

With the continuous progress of urbanization in China,the ecological environment facing the city is becoming more and more prominent.The lack of water resources and the serious pollution of urban water environment make the hydrological mechanism and hydrological circulation in the natural state continue to be destroyed,which has become an important constraint of urban development.River is the birthplace of mankind,urban waterfront landscape is a popular activity space,but also an important research and practice area of urban and rural planning.In recent years,with the development of low-impact development concept and the continuous development of rainwater management technology,waterfront space research also emerged many new content.The traditional technology and methods can no longer meet the requirements of urban sustainable development,"sponge city" concept came into being and became the breakthrough point to solve the problem of urban water environment.It advocates the benign intervention of the ecosystem;advocates the city and the nature as a whole to study and deal with;advocates the combination alternate city and nature.In this paper,urban waterfront landscape is the research object.Combined with the new rainwater management concept-"sponge city",this paper analyzes the necessity and feasibility of "Sponge city" concept applied in the urban waterfront landscape design;combs the city waterfront landscape and sponge city related theoretical knowledge;analyzes two cases of sponge-type urban waterfront landscape design in depth;puts forward the design method of urban waterfront landscape under the infiltration of sponge city concept from the perspective of landscape planning and design.Taking the waterfront landscape design along the Fujiang River in Mianyang City as an example,the actual operability of the method is proved.The project builds a comprehensive waterfront park which sets water conservancy,ecology,recreation,landscape,humanities and other multiple functions in one.It plays the function of its river infrastructure at the same time,stimulated the waterfront landscape socialbenefits,ecological and environmental benefits,economic benefits,human benefits and other diverse values.It can be seen that this method is worthy of reference and continuous research.
