Study On Engineering Of Environment And Landscape Restoration Of Expressway

With the sustainable, fast and healthy development of Chinese economy, and the implementation of strategy of the Western-Exploitation, the construction of expressway is developing with an unprecedented high speed. At the same time, it brings some problems about environment, which have been paid much importance by some departments concerned. And some correlative measures have been done, plenty of fund is spent on the study and practice of engineering of Environment and Landscape Restoration of Expressway. Although some achievements have been obtained, further research should be carried out. It will perfect the theories of engineering of Environment and Landscape Restoration of Expressway, which will direct the practice, and produce manifest environmental social and economic benefits. According to the practical item of the Southern Section of Lei-Yi Expressway of Hunan Province, and in the light of the specific links (the engineering of Environment and Landscape Restoration of the main lines of expressway, the inter-crossing and the service areas) and the implementing steps of the engineering (planning and designing of the engineering, invite and submit tenders, construction and maintenance, supervision and management of the engineering), this dissertation elaborates the theories of engineering of Environment and Landscape Restoration of Expressway in detail, and makes a practical operating model of engineering of Environment and Landscape Restoration of Expressway. This model analyzes the environmental ecological effects, the landscape effects, and the landscape culture of each part of the engineering of environment and landscape restoration of expressway, especially emphasizes the environment and landscape restoring methods, and it also puts forward the necessity of establishing the supervising and managing system of landscape engineering and some related implemental measures.
