Study On Benefits And Measures Of Ecological Restoration For Mountainous Expressway

This paper takes mountainous expressway as the research object, analyzed the characteristics of mountain-specific environment on geology and landform, concluded the uniqueness of construction of mountainous expressway, researched the construction of mountainous expressway impact on the ecological environment, and in accordance with the expressway engineering division,summarized how to prevent ecological disaster and implement measures of ecological restoration under different engineering properties.In order to prove that investment in environmental protection in expressway engineering is feasible, the ecological environment along the expressway was divided into six categories,include the water environment, soil environment, atmospheric environment, acoustic environment, biological environment, landscape environment. Researched how to take preventive measures of environmental pollution above the construction of expressway under various environmental conditions;The focus to analyzed the benefits of ecological restoration after ecological restoration measures under the different environmental categories,and in order to monetize benefits of ecological restoration,cited the most representative eco-efficiency indicators, and take monetary value of index that can not be directly converted used alternative construction method,so established monetary calculation models of the eco-efficiency indicators;and combined the practical engineering case, benefits of ecological restoration was quantified into a unified monetary value,compared with the investment of environmental protection, will help in all links to see a huge value of the potential benefits in environment investment, thereby increasing environmental regulation, the implementation efforts.
