The Research On Landscape Design With Plant Of City Green Space In Collecting And Using To Rainwater

Our country is rich in water but also serious shortage of water, how to realize the use of rainwater collection has become an urgent problems, which needs to be solved in the limited space in the city. In recent years, domestic and foreign use of rainwater collection and landscape design already have a lot of successful cases, the theory and method is also more and more mature, however, the research to realizing landscape design with plant in the collecting and use of rainwater in the city green space is lack of a system design method.Based on the construction of rainwater collection and utilization function of green space as the goal, this paper was use of literature study and theoretical analysis method, comparative analysis method, induction and deduction method, the design practice method, the method of investigation and research, combined with the excellent cases, summed up the domestic design points and direction of rainwater collection and utilization of landscape design with plant in city green space, the research contents and results are as follows:(1)The paper discussed a process which is combing the development of rainwater collection and utilization technology with landscape design with plant from the aspect of theory, this process is start from blank. The landscape design in city now is lack of coordination with the using of rainwater collection facilities to realize the function of water collection, purification and retention in green space.(2)Through the analysis of excellent practice examples at home and abroad, this paper summed up the ways in the use of rainwater collection procedures and methods for landscape design with plant, which is from the different types of green rainwater collection process firstly, design the space to meet the various features in green space by the landscape design with plants. Summarizing four characteristics of landscape plant design of use of rainwater collection in green space, which is form the terrain aspect, green space presents significantly characteristics, the plant material often uses the strong vitality plant, plant community structure adopts multi-level composite structure model, plant always have close relationship with various forms of water.(3)The paper summed up the basic problem in the use of rainwater collection procedures in the domestic green space, the most remarkably problem is lack of attention, the city is lack of overall planning macroscopically and pertinence design in detail. So we must according to the different types of green space corresponding with suitable rainwater utilization facilities to realize plants design.(4) The paper have chosen Zhuzhou as the research object, draw a conclusion that the landscape plant design in the city is lack of awareness and planning in the rainwater collection and utilization strategy, So we put forward rainwater collection and utilization strategy in green space of landscape plant planning and design theory in Zhuzhou:combined with the natural landscape of the city of Zhuzhou City theoretically, to achieve the layout in the use of rainwater collection of plant landscape design with plant in green space, chose Guandian dam as an example practically, based on the natural conditions, construction hydrologic environment to create the function of collecting rainwater landscape plant design and plant configuration mode. Thus demonstrates it is scientific in creating rainwater collection and utilization landscape design with plant in green space.The research results show that the urban green space rainwater collection and utilization of landscape plant design method is different from common landscape plant design, which must according to green space layout in city on the macro and plant landscape design in green space. We must consider it fully and realize ecological service function, the research result will provide a reference for rainwater collection and using in the city green space.
