Research On Urban Park Design Based On Stormwater Management Planning System

The current construction of the new city shows the trend of Chinese construction level,also represents the advanced direction of sustainable city developing.The main content of study is combined with our current city planning theory.Author summarizes the theory frame and method of China City stormwater management system planning systematically,as basis of Qian'an urban construction stormwater management planning technical.The main contents are as follows:1.The main idea of stormwater management is the establishing ecological infrastructure planning,ecological infrastructure in ecological system is mainly concerned with of flood control,protection of water quality,runoff reduction,clean water and other aspects within the natural function,emphasizing the natural Water runoff and deployment of engineering facilities.Stormwater management planning media conclude centralized pooling,end control carrier and local use,evacuation source and process control carrier,transmission carrier and other parts.2.The urban stormwater control management plan is based on the urban planning system.The overall planning is mainly focused on the overall pattern of stormwater management and the source reduction plan of the storage unit.The landscape security pattern of stormwater management as the final goal of the planning is the requirement of the overall planning.The regulatory detailed planning focuses on the transmission carrier planning and the results of final indicators of the plan also contain the effective permeable surface index and the effective green space;the constructive detailed planning makes design of the ecological infrastructure of the stormwater transmission carrier and is applied to the actual project landscape design and construction specifically.1.Urban stormwater management master planCombined with the overall planning of the city,considering the simulation of the spatial situation,the Qian'an urban stormwater management of the savings unit division,the stormwater management overall planning objectives and the level of runoff data and other indicators should be analysed.The construction of the regional stormwater management landscape security pattern takes suitability assessment system of the basic storage unit into consideration,and runoff to reduce the spatial location and combination of the green infrastructure.2.Urban stormwater management regulatory detailed planningAccording to the different classification of the underlying surface,city must take effective water surface planning indicators.Based on the field of information obtained,dividing the areas can determine the runoff indicators,Such as subsidence green rate,etc.,at the same time,to make sure the various types of green space function and mode of operation in accordance with the planning.3.Landscape Design of Stormwater Management under Constructive detailed planningThe one sides of Qian'an Binhu East Road will be planned to design the park green space for a specific landspace.Under the index control system,there are combination of stone cage plant filter pool,multi-level wetland purification system,many wet plants composed of leaking ditches and other purification of ecological infrastructure.
