The Practice And Research Of Greening Landscape In Tongchuan To Xunyi Expressway

The infrastructure in China,especially highway construction,has got a big development by a surprising speed.However,the construction level of the highway landscape in China is still relative backward,and the traditional landscape design theory could not meet the current demands of highway landscape practice.In this paper,we took the landscape construction of Tongchuan to Xunyi expressway as an example,and analyzed the landscape construction of the expressway from five aspects:Firstly,we read the original landscape design of Tongchuan to Xunyi Expressway,then investigated the construction site to find out the existed problems,such as the site not in conformity with the design,design omissions,and unfeasible design scheme.Secondly,we proposed the greening landscape tree species which were suitable for this project according to the local natural geographical conditions and plant resources.Thirdly,we held a review meeting and pointed out a suitable plan for this project to solve the disadvantages of the design.Fourthly,we put forward the work procedure of the expressway greening project before construction,construction technology points,and later maintenance management measures in order to provide the basis for the construction of the greening landscape,according to the construction requirements for mountainous area highway greening landscape.Lastly,we proposed five suggestions for this highway landscape construction,based on the previous research,greening construction and management experience.
