Design Of ChaoHu BinHe Park Based On Low Impact Development

With the continuous improvement of urbanization in China,the urban population is increasing,and the area of urban built area has been greatly expanded.The original natural ecological surface has been damaged and replaced by hard pavement and reinforced concrete.The surge of impervious area makes the urban natural water circulation system seriously affected,the natural habitat is subjected to irreversible damage,the city can not withstand the heavy rainfall,urban waterlogging has become the most urgent problem to be solved in our country.How to use the different rainwater periods and the utilization of rainwater resources have become the common problems faced by the vast majority of cities in China.Park green space has become a city green lung,is to restore the city's natural water cycle and improve the ecological environment of the most effective and most economical way.However,in most cities in our country,the planning and design of urban parks are often one-sided pursuit of external manifestations,ignoring its urban rainwater,ecological Environmental restoration and other aspects of the intrinsic function,so to some extent,our city park design there is a lot of room for improvement.This research,through the study of technical measures of low impact development,creatively combines it with urban park design,puts forward the new idea of urban park design,perfects the urban park ecological function and reduces the damage caused by urban development to the site.In this paper,the low impact of the development of technology carried out a detailed comb,summed up the green roof,planting grass ditch,rain garden,biological detention pool and other technical characteristics and scope of use and conditions.Through low-impact development of technology landscape application,urban park low impact development not only has good landscape effect,at the same time to achieve the rainwater runoff reduction,rainwater resources utilization and ecological environment recovery purposes.At the end of this paper,taking Chaohu Riverside Park as an example,the application of low impact development technology in urban parks is demonstrated in detail.And use the SWMM rainstorm management model to make a comparative evaluation of the rainwater control effect of the planning scheme of the Chaohu Riverside Park based on the low impact development concept and the planning scheme without using the low impact development concept.Through the correlation data and chart analysis,The design scheme that affects the development of technology has a significant effect on the reduction of rainwater runoff and the purification of water quality.The simulation results confirm the feasibility of the urban park landscape design method based on the low impact development concept,and have some reference significance for other similar park design.
