Reconstruction Design Of The Landscape Environment Of Ban Shi Xia Village In Guangzhou Based On The Concept Of Sponge City

The sponge city put forward is undoubtedly the important milepost in China’s ecological city construction,sponge city as a national policy,reveals China’s water management into a new historical period.Water is the city’s blood,but also the lifeblood of the city.In recent years,more and more cities access the rainy season after heavy rains,about on the "inland look at the sea" examples can be found everywhere.Now many cities have serious waterlogging,because of the city in the development and construction of the neglect of the ecological environment at the beginning of the natural cycle,the use of hardened ground in large area,resulting in rain cannot be seepage in time,then caused flooding disasters.This problem is not only use a few years or decades the sewer pipe set standard can solved,but also flood disaster cannot be solved,and there are also unreasonable plans for underground pipe networks.When the large area of land is occupied by the not permeable pavement and buildings,the rain cannot be naturally cycle,only discharge through the municipal pipe network,if the multiple peaks stacked together,rainwater pipe network unable to resolve,will soon form waterlogging and rainwater intrusion problems.This neglect of natural ecology and rain at the end of the city development to be regulated and discharge design technique,will only make the city waterlogging is more and more serious,at the same time also affected People’s Daily life.Facing the increasing and the expansion of the urban population,Just overstriking the underground pipe network size,but still use the traditional method,On the one hand,in heavy rain that already cannot meet the requirements of discharge the water,on the other hand,serious damage to the natural circulation of ecological system,The vicious circle of two causes that people has to find a best plan and a virtuous circle of design method and planning and construction technology,the sponge city concept came into being.The Sponge city will be better implementation of regional and urban rain flood into resources,also can effectively adjust the local climate environment,increase is suitable for biological survival environment,and protection of historical and cultural.At the same time increase the city’s green area,in the heavy rain can be surface infiltration timely.the use of green space for rainwater retention to reduce surface runoff.with using plant purification effect and reduce non-point source pollution with reduction the harm of flood drought.First of all.this study summarized using the summarization of the city of rain flood management at home and abroad advanced ideas,and when heavy storm comes that used the standardize the technical measures taken and so on carries on the analysis and summary,gradually in the developed countries come to the low impact development idea and concept of the sponge city in China have in common,then according to the development of our country sponge combing the concept of the city.At the same time analyzes the concept of urban sponge in different scales and different regions example.The ban Shi Xia village landscape environment reconstruction in Guangzhou as the research object,excavate the development pattern which is suitable for China’s national conditions of sponge city.
