The Research On Methods Of Landscape Of The Urban Stormwater Management

At present,the land of the original hydrological conditions has been marred by rapid urbanization,flood,water pollution,water scarcity problems emerge in endlessly.Traditional predominantly fast row,flood control gray infrastructure,its function is relatively single,lack of the ecological environment,the value of rainwater management,scale construction also lags far behind the development of the city,the moment has been unable to solve the problem of increasingly severe rain flood.In this paper,based on the rain flood management of the northwest region of city park landscape design method,aimed at from the expansion of the landscape architecture of less rainfall over northwest China the rain flood management way,has positive significance to its sustainable development in the region.Paper first by defining the scope of the study of the rain flood management,and according to the research background and content,the analysis of the current to the urban park landscape design development of the rain flood management development trend.Based on the research of relevant theories,the good rain hung park landscape cases at home and abroad were reviewed and interpreted,put forward the planning level needs to be based on the natural hydrological processes,the design level needs to be rain flood management into its basic link;And give priority to with case,rainfall in China much of the northeast area of the northwestern region of city parks and low rainfall rain flood management analysis,summed up the different of the two,for later design method and the practical case.Thesis emphatically elaborated based on the rain flood control and management of northwest urban park landscape design method.First elaborates the purposes and principles of design,and design method for the specific instructions,through the integration of outside the park and urban water circulation system,improve the utilization of urban rainwater resources;Park rain mainly dominated by runoff design,reasonable setting related collect water from the rain flood management facilities,using landscape formation reservoir in the form of lake,the lake slow flow velocity,reduce the peak flow,adjust the time and space distribution,at the same time provide physical settlement,purification of natural restoration techniques such as rain,protect the environment,optimization of water resource utilization;Through the special park landscape design,the reasonable use of existing resources,promote the sustainable development of the landscape.Paper finally has carried on the empirical case studies,in order to baoji panlong lake,one thousand mu ecological leisure park landscape design as sample,details the practice project based on the current situation of local rainfall conditions,land ecological method of rain flood management techniques,as well as provides the similar of hydrology and climate region city parks rain flood management system for reference.
