Study On Comprehensive Evaluation Of Landscape Design Of Rainwater Garden Based On Sponge City Concept

Establishment of sponge city,from the point of view,the city to solve the water logging problem,improve the city water management system,onservation of groundwater resources,the formation of benign water cycle,the greatest degree of restoration of ecological environment.As the entity of the sponge city,the rainwater garden carries the main tasks of controlling rainwater and optimizing the ecology and promoting the water purification cycle.The rain garden,is named of a garden related to the rain.It is an artificial ecologically sustainable rainwater utilization and rainwater control facility,mainly composed of concave green land,through the sand and the role of plants to deal with the recovery of water.The rain garden has many functions like restoring green ecological benefits,setting up a good landscape,solving the problem of the city waterlogging and purifying water.It has important theoretical and practical significance,how to effectively based on the concept of low-impact development,through the design of the rain garden landscape to maximize to achieve the expected benefits.This will be the topic of this paper.First of all,this paper combs the basic content of low-impact development of sponge city and the related theory of research progress at home and abroad.Put forward the research content,method and innovation of the thesis.Secondly,from the concept of sponge city and rainwater garden,analyzing the relationship between the concept of sponge city and rainwater garden and the design principle of rainwater garden under the influence of sponge city and construction of sponge city.Thirdly,it explores the factors of rainwater garden landscape and the main factors that affect its future landscape design,including visual aesthetic,social function and environmental condition.It is the foundation for the construction of the evaluation index system of the landscape design of the rainwater garden.Finally,the paper analyzed the case ofShanghai Houtan Park and Jinhua Yanwei Zhou Park to determine the low impact of the development of rainwater garden on the control of rainwater and purification of water conservation with setting up indicators and reviews,using the comprehensive fuzzy evaluation method,constructing model of rainwater garden landscape design in sponge city,using expert scoring and calculating weights has a significant effect.This paper provide a quantitative basis on the concept of low impact developing rainwater garden landscape design.The research shows This paper established the Fuzzy evaluation is effective,The case of Shanghai Beach Park and Jinhua park design are good.
