Research On Ecological Landscape Design Of Residential District Guided By Urban Stormwater Management In Changsha

Residential areas is a special carrier for human living and a sign of the progress of human civilization.A favorable ecological landscape design of residential district can not only provides a livable ecological environment for residents but also satisfies the desire of a better life.But with the acceleration of urbanization,the urban ecological system is destroyed and ecological environment of our residential district is facing a great challenge.While in Changsha residential areas where serious waterlogging disasters occur frequently,traditional rain treatment models can not meet the functional requirements any more.How to integrate the stormwater management with ecological landscape design is a question worth thinking about.The essay is about stormwater management and focuses on the ecological landscape design of Changsha residential areas,the main research contexts consist of:First,elaborating the meanings of stormwater management,residential district and ecological landscape design based on searching domestic and foreign literature,and providing theoretical basis and case supporting of Changsha residential district design model by analyzing domestic and foreign projects.Second,discovering the relationship between stormwater management,residential districts and ecological landscape design,telling the inner connections of them by analyzing their development processes.And elaborating how urban stormwater management affects the ecological landscape design of Changsha residential areas by analyzing the elements of topography,plantings,water features,paving materials and sculptures,and as well as other influencing factors such as location,physiognomy,hydrology,climate,policy.Third,proposing the problems of project development,stormwater management,plant configuration,cultural connotation and maintenance based on current situations of Changsha ecological landscape design.Putting forward the design guiding ideology of functional carrier of stormwater management,demonstrating carrier of ecological landscape,concept carrier of sustainable development,Combing stormwater management with residential landscape design model solutions,including how to design topography,plantings,water features and paving materials under the background of low-impact-development.The solution will bring effective stormwater management functions,abundant biodiversities and good landscape effects to residential ecological landscape design.Last,taking an example of hill-side eco park and analyzing the current site conditions,proposing the stormwater management model,including collecting,purifying,containing,infiltrating,discharging and recycling of rainwater.What’s more,building a system of making an overall utilization of rain resources according to practical needs and designing landscape functional spaces with rain like rain garden,Archimedes garden and water-falling plaza.The essay gives a comprehensive analysis from the perspective of stormwater management,putting forward relevant design concepts and models,elaborating the feasibility of the model and bringing reference values to ecological design of local residential areas.
