Regulation Model of Environmental Impact in Expressway Construction Based on Jieke Theory

In accordance with present situation about environment impact of expressway construction and deficiency in environmental protection measures of expressway construction, jieke theory was used to analyze the jieke sectors of eco-environment and their roles. Basic concept and structure of eco-environment system was elaborated, and its application prospect in environment protection of expressway construction was analyzed. At last, regulation model of environmental impact in expressway construction was put forward. By the model, eco-environment impacts can be dynamically adjusted in the process of expressway construction. Further, on the precondition of ensuring natural expressway construction, environmental impacts were quantitatively reduced to the minimum extent. It provides researchers with a new thought and method about eco-environmental impact of expressway construction.
