Planning And Design Strategies Research Of The Country Park With The Construction Of Rainwater Harvesting Based Green Space

With the accelerated process of urbanization,the rapid growth of the city has brought a serious problem of urban rain and flood,the rapid population growth has also led to the growing demand for urban residents to the natural environment.Therefore,the construction of rainwater harvesting green land and country parks has become the inevitable trend of urban development.Through literature survey,country parks and catchment type green case and field surveys and other research methods,the definition of country parks and green space after the rain,worked out for the planning and design strategy of country park green space construction based on rainwater,through the use of internal field rainwater collection and in order to achieve the country the interior of the park water self-sufficiency,and the premise for resource protection under the construction of Country Park native landscape,to create the country landscape and recreational activities in city park.This paper takes the Shijiazhuang Piedmont Avenue country park as an example,based on the status of the special conditions of site,on the basis of analyzing the present situation of ecological sensitivity by GIS platform analysis make site land suitability analysis,planning and design of land for the site at different.Engineering and technical measures in order to protect the site situation based on the premise of park design into rainwater green space,in order to achieve site rainwater collection and utilization.By calculating the site rainwater volume and residual capacity of rainwater evaporation and infiltration after the design of the site in the rain and to obtain the site of rainwater in self support;under the premise of meet the site of rainwater collection and SWMM model under the rain simulation,verify the park design in a variety of storm intensity under the end of the flow.In order to verify whether the park design can meet the requirements of rainwater and rainwater treatment.
