Research On The Integration Design Of Residential Area Landscape And Sponge Function

Since the reform and opening up,China has entered a stage of rapid urbanization development,with urban waterlogging,water shortage,water quality degradation,heat island effect and other problems becoming more and more prominent.In order to carry out the concept of sustainable development,experts and scholars at home and abroad put forward the theory of "sponge city" in view of urban waterlogging,water quality degradation and other problems.Through the construction of a new city with the function of "sponge",so that it has the function of "natural accumulation,natural penetration,natural purification",it can store rainwater when it rains,and release rainwater for use when it usually uses water.At the same time,it also has a certain degree of purification ability.In the link of urban construction,residential area accounts for a very high proportion,and residential area is a very important environment in the urban ecosystem.However,in the face of serious urban water environment problems,the current situation of rainwater management mode in residential areas has shown a weak situation.The rainwater management mode under the sponge city concept,which emphasizes "source management,process reduction and terminal control",has become the construction standard of new residential areas.Designers in the landscape design,should make full use of hysteresis,net "infiltration,storage,use," relevant technical measures to build systematic rainwater management method,combining with the characteristics of water supply and drainage,landscape,architecture and so on various professional,reasonable planning scientifically square,green land,road layout,make full use of all kinds of sponge facilities,realization of rainwater infiltration in the residential area,its subsistence,purification,Restore or maintain the natural hydrological cycle pattern before site construction to the greatest extent,and realize the sustainable utilization and comprehensive management of rainwater in the residential landscape.Based on the residential area landscape and sponge function design as the research object,first of all,through study abroad the low impact development(LID)sustainable drainage systems(SUDS),Britain,Australia,water sensitive urban design(WSUD)and domestic prof yu,Zhang Qihong,Li Rong experts and scholars of relevant theoretical research results and application examples,Explore the feasibility of integrated design of residential landscape and sponge function.Second,detailing the sponge in the concept of urban residential area landscape design concept and target,analysis of landscape and sponge function integration design,volumetric method and flow method,two kinds of general design method as well as three technology measures,such as penetration,stranded,purification in practical application,to combine the construction site condition,geographical conditions and hydrological conditions such as actual situation,Scientific and reasonable selection of technical measures,collocation and combination of application to achieve the best results.Again,on-the-spot investigation and research of traditional residential area landscape in facing the current lack of humanistic care,lack of integrity,late effect is poor,lack of local characteristics,such as common problems,put forward in the landscape design should firmly seize the moment when the practicability,comfort,residents of landscape ecosystem,applicability,such as physiological and psychological needs,combined with the necessity of integration design,Make full and effective use of various technical measures and landscape elements,adapt to local conditions,and create a green and livable ecological living environment.Then,on the basis of the above research,according to the principles and ideas of integrated design,the intersection point of integrated design of landscape and sponge function in the new residential area is found,and the characteristics and application scenarios of five technical measures,such as road,green landscape,rain garden,ecological grass planting ditch and ecological tree pool,are summarized.Finally to new eco-city in the jre project as an example in detail,the project adopts the Chinese botanical garden landscape,broke through the traditional city construction pattern,sponge sponge through green row storage system,innovation solution to rainwater runoff amount and runoff pollution control facilities,to the effective purification and collecting rainwater,can build a self-regulating micro ecological system.The project would be a perfect fusion to design,landscape and sponge function not only achieved good landscape effect,improve the residential area of the ecological system,at the same time the save resources,reduce the engineering cost,realize the effective balance of the urban development and environmental protection,so as to prove the function of residential area landscape and sponge mix design train of thought is not only is feasible,Moreover,it has a good application prospect and is expected to play a certain reference role in the construction of residential areas in the future.
