Landscape Planning Of Residential Areas Based On Rainwater Movement Trajectory

Rainwater,as one of the sources of urban water resources,plays an important role in the construction for urban double maintenance.But it is worth to discuss how to realize the collection and utilization of rainwater resources through landscape ecological method.This thesis is taken the residential area as the research object,to analyze the movement trajectory of rainwater in physics through literature research,case analysis etc other methods,organically combine each movement trajectory with different components of residential area,and build a five-stage sequence model of residential area landscape based on the movement trajectory of rainwater.It provides reference for the same type of landscape planning.(1)Taking "Rainwater Neighborhood" in Xiongan New Area,Shuangliu Green Building Industrial Park Demonstration area,Maashu Business District in Singapore and High Point Community in the United States as actual cases,combing with the physical process of rainwater formation,to obtain five elements of rainwater movement trajectory:falling node,collection link,transmission stage,retention space and purification process.(2)Analyzing some typical residential landscape cases in China by field research and literature review,to conclude that the residential area consists of four elements:architecture,paving,green space and water body.(3)Merging the five elements of rainwater movement track together with the four elements of residential district,to construct a five-stage landscape sequence model of residential district rainwater track,which is composed of five sequences,namely,the starting scene,the development,the high tide,the ending scene and the end scene.In view of existed problems in each sequence,planning objectives and making strategies.(4)Five-stage landscape sequence planning strategies of rainwater track in residential areas: Scene-setting landscape planning strategy: ecological water saving-by using hydrophobic materials to reduce rainwater loss;Landscape planning: adopting the streamline design on the architectural appearance and the architectural eaves studying from the artistic design of classical gardens.Development landscape planning strategy:ecological water saving: combing with roof planting design to control rainwater loss from the source;organizing ecological trails and increasing permeable pavement.Landscape planning: enriching the form of green space,paying attention to the collocation of plants,enhancing landscape effect;arranging the waterfall,fountain landscape to increase its interest.Climax landscape planning strategy: ecological water saving: transmitting rainwater direcitonally to achieve directional rainwater transmission.Landscape planning:adding rainwater transmission colorfully: by inserting Short Sketch to realize auditory resonance by collision its sound with the sound of rainwater.Integrated landscape planning strategy: ecological water saving: using environmental characteristics,combining with road and green space,etc.,to save construction costs and increase rainwater storage.Landscape planning: Adding colors for rainwater facilities,linear design and plant landscape creation to enrich the landscape effect.Tail landscape planning strategy:ecological water saving: taking plant communities to purify rainwater in a natural way,to reduce the cost of construction and maintenance of purification facilities.Landscape planning: Enriching the landscape of plant community and increasing the sense of landscape hierarchy.(5)Taking Huabang·Huamili Residential District as an example: on basis of in-depth investigation of the site,by combing with the five-stage landscape space planning strategy of residential rainwater track and taking a plan for the four elements of the residential district,like architecture,paving,green space and waterscape,to enrich the ecological landscape of residential rainwater and create a natural,comfortable and pleasant living environment.
