Research Of Ecological Courtyard Space Landscape Design

Shanghai,which is positioned as a pilot city,should play a leading role in the construction of sponge cities.Introducing the concept of the ecological design into the courtyard landscape design can not only effectively and rationally make full use of rain water resources,but also help improve the ecological environment.At the same time,it is a response to the policy of sponge city construction and has a broad application prospect.This paper discusses the design mode and method of upgrading the courtyard landscape of the city under the concept of ecological design to make it a sponge in the economical city,aiming at the effective design of the urban courtyard landscape ecologically and beautifully,and improving the implementability of the small urban sponges.This paper is divided into three parts to discuss the landscape ecological design of the courtyard space.First,by introducin the design concept and design principle of landscape ecological design of courtyard space and its main functions in urban construction are expounded in detail in this paper.Based on the analysis and research of Tsinghua Shengyin courtyard,Portland Tanner Springs rain garden and Brooklyn "urban oasis",the paper summarizes the ecological design idea,design method and implementation method used in each design case,and verified that the design concept and the design principle of landscape ecological design of courtyard space can be applied to the ecological urban construction.Then by introducing the precipitation,soil and climate environment of the courtyard in Shanghai,this paper summarized the problems that the ecological design of the courtyard needs to be solved,the key factors of the ecological design of the courtyard,and the requirements of the design.Then,in the form of field observation record and interview conversation,the paper makes a preliminary investigation on the landscape status of six typical zones in Shanghai,objectively summarized some common problems in the design of the courtyard landscape in Shanghai.The paper also puts forward the corresponding solutions and design ideas and points out that the current designs of the courtyard landscape in Shanghai are more ornamental and less ecological and have low utilization of resources such as Rain Water.Therefore,combining the ecological design concept with courtyard space design is an important direction and necessary trend of the late development of the courtyard landscape in Shanghai.At last,combining theory with practice,author carried on the reconstruction and upgrading design to three existing courtyards in Shanghai Yupin garden housing estate,Beiji medical factory courtyard,and Bangzhong factory courtyard from the aspects of topography,ecological paving,water circulation treatment and plants.Then author conducted a benefit analysis from the perspective of landscape,economy and ecology,which further verified the practicality of the theory of landscape ecological design in courtyard space.
