The Southwest Water Elasticity Of Urban Green Space Landscape Design Research

With global warming, extreme weather and serious flooding in city, in recent years, our country city facing the seasonal rain flood damage is also increasing. Rapid urbanization movement has caused most of the cities in our country face the sudden natural disasters and secondary disaster response capacity is weak. This paper is dedicated to explore urban green space landscape design, based on the theory of the elasticity of water and water elasticity of urban green space landscape design in southwest area as a practical case for a detailed analysis.In this paper, printed and distributed by the state council \"about the sponge of urban construction technology guide, low impact development of rainwater system build(try out)\" and \"sponge technology guide urban construction and so on policy, then discusses the present status of urban drainage infrastructure is relatively backward, and the national popularized for urban water elastic green space landscape infrastructure construction work seriously, take the policy advantage into water elasticity of urban green space landscape design study.In this paper, based on the hydroelastic the history of urban design and related theory, combing the domestic and foreign water elasticity of urban design as the leading landscape good practice case study and the methods and techniques. In water elastic system of urban design research methods are summarized, on the basis of such as LID, BMPS, WUDS, SUDS in major methodology, design strategy and integrating with elastic design technology, such as permeability, hysteresis, net, use, storage, and other technical means; Locate in the southwest water elastic design practice cases, effective in theory to guide practice, based on the hydroelastic city green space landscape design goal principle, the technical measures such as examples to carry out the water elasticity of urban green space landscape design.By design practice in the southwest region, from the Angle of the water elasticity of urban landscape design, put forward from macroscopic to microcosmic layout in different levels of rain flood management, habitat protection, and the rain garden design, in order to follow the terrain space maintenance ecological boundary build water elasticity of urban green space landscape design.analyzing the results of this study summarized on chengdu-chongqing practical cases on behalf of the city in the southwest water elastic similarities and differences in urban green space landscape design to express the design related focus attention. Proposed to the southwest water elasticity of urban green space landscape design and construction measures. The author on the practical experience and research provide still have deficiencies can be strengthened.
