Study On Adaptive Planning Of Urban Water Environment Landscape Under The Background Of Sponge City Construction

Under the background of the continuous deterioration of urban water environment problems,urban rain storm management concepts and practices,and the state’s promotion of the construction of sponge cities and dual urban repairs,this study aims to identify the characteristics of water environment,current water environment issues,and water landscape issues.Recognize and reflect on the root causes of urban water environment and water landscape planning.Through the study and research on successful sponge city construction,stormwater landscape planning,adaptive planning,and flexible planning,both at home and abroad,from the perspective of adaptive planning,the paper explores the adaptive planning framework for urban water environment landscape planning.,Including adaptive planning objectives,adaptive planning principles,adaptive subjects and objects,adaptive mechanisms,adaptive analysis and decision-making,and adaptive planning strategies,exploring the establishment of urban water environment landscape planning and regional water environment characteristics,water environment Relevant environmental element features,living environment needs,climate change and other objective environmental changes collaborative,adaptive,sustainable development of water environment landscape adaptive planning theory and methodological framework.The main contents of the urban water environment landscape adaptability planning framework include:(1)The adaptive subject and object of the water environment landscape planning:①Water environment landscape planning and adaptation of regional water environment characteristics;②Water environment landscape planning and Regional water environment-related adaptation of the characteristics of environmental factors;③ Water environment landscape planning and human habitat security,health,comfort and demand for collaborative adaptation;④Water environment landscape planning to adapt to climate change;(2)The adaptive target of the water environment landscape planning:①Urban water environment ecological protection,restoration and appropriate transformation;②Urban water environment landscape security assurance,elastic adaptation to flood and extreme climate;③Urban water environment Landscape landscaping and water landscape function optimization;④Urban water environment landscape rational and full use of water resources;⑤Urban water environment landscape environmental quality governance and improvement;(3)The adaptive analysis evaluation and decision-making methods based on collective planners,government departments,experts in various disciplines and publics:objective analysis and decision-making,government decision-making,expert decision-making,Public participation;Adaptive analysis,evaluation and decision-making process include:①Preliminary research and analysis,put forward the initial plan concept;②medium-term program simulation analysis and re-decision,determine the planning program;③post-project implementation of monitoring analysis and maintenance management;(4)The adaptive planning strategy system of water environment landscape planning from the macroscopic urban basin to the microscopic site catchment unit:①Macro-scale urban middle and small watershed scales:Construct the water environment ecological protection space based on the overall landscape of urban water environment landscape Pattern and water environment security protection space pattern,to a certain extent,protect the ecological environment of the water environment and the city’s water environment security,limit the city’s disorderly development and construction,and ultimately build the city’s"water green,green and green complementary" landscape space pattern;②Small-scale and micro-basin scales in urban areas:Starting from the functional zoning of water environment landscape in urban areas,within a limited spatial scope,rational and scientific control of land development,protection of the natural ecological base of the city,and restoration of irrational land use attributes and ecological functions.By analyzing the ecological sensitivity and construction suitability of the water environment in the area,the landscape sensitivity,suitability,adaptive management and control zoning planning and urban river and lake water landscape adaptability planning strategies for the urban area are constructed;③The site catchment unit scale:Based on the analysisDesign-simulation-redesign cycle verification process realizes multi-level coupling of form-ecology-function adaptability,proposes site water environmental landscape adaptability from rainwater landscape planning and design strategies,rainwater landscape measures,and ecological engineering methods.Planning Strategy.
