The Reaserch Of Reconstruction Design Of Rainwater Garden In Chengdu Eastern Music Park

With the rapid development of productive force and science and technology since China’ reform and opening up, the process of urbanization has accelerated rapidly. Under this circumstance, a mass of trees, lands and cultivated areas have declined quickly due to be covered with waterproof buildings, squares and roads. The storm water problem brought by urbanization has hard hit in human’s normal production and life. On November, 2014, the National Department of Housing Construction issued The Guide of Constructive Technology for "Sponge City" which put forward relevant content about construction of rainwater garden. As a important part of urban development and construction, building rainwater garden in city parks can not only reduce the storm water runoff and ease the pressure of urban drainage, but also can prevent natural disasters caused by rainwater.Chengdu eastern music park is located in No. 4, JianShe Road(South), ChengHua District,ChengDu City, SiChuan Province. This city park was born out of the rebirth of the old red light tube factory owned by state. This paper takes eastern music park as an example to study the design expression of rainwater garden view in city parks.Through the methods of literature analysis, field survey and induction, this paper makes theoretical and practical study on the research process and relevant content of rainwater garden in domestic and international, and the rainwater utilization in city parks. This research aims to integrate in rainwater garden and city parks, explore related theoretical and practical basis and provide reference for future design of rainwater garden. From the current situation, this paper explores in depth the better pattern of rainwater garden which will be more in line with regionalism, culture, ecology and functionality. On the premise of keeping the old site, the design combines historical culture with musical elements to provide citizens a city park integrating relaxation and entertainment through the design of rainwater garden which could demand rainwater utilization.Through the research on Chengdu rainwater music garden landscape design to the following conclusion:First of all, through the analysis about the present situation of eastern music park of chengdu area, sums up the three types of green space within the site: the dotted green space, green space and linear green space.According to according to the design of three types of green space will be divided into the rain garden dotted the rain garden area, linear rain garden area and shape of the form of rain garden area, under the condition of the meet site its function layout within the park and build park rainwater garden facilities, both to enhance the internal landscape park, and the rain garden on the corresponding function of rain.Secondly, the design of red light tube factory, summarizes the history and culture analysis, keep and use the original factory production in the legacy of rust plate waste, scrap metal box, etc., and its extraction processing for landscape elements, make irregular wall of landscape, landscape seats, etc., combined with the rain garden, applied to the design expression and inheriting the historical context.Finally, explore and discover the music element in the landscape design expression form, combining its and rain garden, performance of music thematic park.In memory by industry garden, east of the road and the road of music line combination, in the shape of staff, enables participants to put to go with music in the spiritual path;In the red memory garden, look like a different length of the piano keys of rainwater garden box, let the participant feel by garden box play music melody.Through music Chengdu rain garden landscape design, this paper will rain garden combining with history, culture, music elements.Provide a reference for similar design.
