Research On Flood Adaptive Landscape In Perspective Of Ecology Resilient Cities

Under the background of global climate warming,the flooding disaster takes place frequently in cities and shows an increasingly severe trend.The city has entered a risky era of hydrological disasters.However,the traditional defensive way of thinking based on "discharge" has formed an urban flood defense system mainly composed of gray engineering facilities.This system not only isolates the natural system carrying the metabolic flow and energy cycle of urban ecological materials,but also increases the vulnerability and risk level of the city itself to deal with danger.Therefore,the construction of ecological urban defensive infrastructure has become a hot area of research,and the flood adaptive landscape associated with overflowing water bodies can also play an increasingly important role.How to indroduce the concept of ecological resilient city and help the city to better cope with flooding disasters using the construction of flood adaptive landscape,has become the starting point of this paper.This paper first explains the concepts of ecological resilient city,adaptability and so on,as well as teases out and researchs the formation and development process of urban resilience theory.Through the interpretaion and analysis of the theory,this paper summarizes theoretical principles to improve urban ecological resilience and the enlightenment to the area of urban planning,and differentiates the theory from the current hot sponge city theory.Then this paper analyzes floods and the flood disaster,dissects the evolution process,influential factors and disaster forms of the flooding process,and defines the forms and scales of flood adaptive landscape.Next,this paper discusses the feasibility and necessity of the combination of ecological resilient city and flood adaptive landscape,also puts forward the framework system of resilient flood adaptive landscape construction.Afterwards,this paper explores flood adaptive landscape strategies under the view of ecological resilient city respectively from three aspects:patch,corridor and matrix.Finally,this paper takes the lake landscape of Wuhan as research object and proposes strategies and suggestions for the flood adaptive landscape construction of lakes in Wuhan from the perspective of ecological resilient city.Based on the theory of ecological resilient city,this paper,from the perspective of urban overall ecological infrastructure,guides the urban landscape to deal with flood disturbance and disaster as well as puts forward adaptive strategies and suggestions,trying to construct a resilient and ecological urban flood multi-layer protection system mostly composed of landscape facilities and direct the application of theory in reality.
