Study On The Ecological Regionalization In Mountain Area's Expressway Construction Region

The expressway construction has become a focus for investment of our country infrastructure,while expressway construction also aggravated the contradiction between the resources, the environment and population, environmental issues outstanding. how to manage the expressway ecological environment effectively and Sustainably,it has becoming a hot spot of the study at home and abroad. Before,the expressway environmental protection work is still be confined to tree planting or grass planting at present,but in recent years, attention to the pattern of regional ecological engineering model,and our country's environmental protection design and the management have begun to pay attention to the road environment features integrated ecology, landscape features, traffic ancillary services.This paper first reviews the research results on the road natural regionalization, the ecology regionalization, the ecology area construction along road ,Union ecology, environmental, road engineering, and multi-disciplinary synthesis, clarifying the highway construction division of the regional eco - objectives and methodologies.base on the characteristic and the realization goal of the Environmental Protection along the object about the XiHan expressway, Established the Ecological Regionalization Index System,and given various single items factor and the synthesis factor assessment method. Combining ecological control theory and cluster analysis method based on SPSS,use of geographic information software divided the regional of expressway construction into different ecological functions units, analysis of ecological sensitivity and ecosystem function service to seek ecological construction targets. This paper will attempt to apply the concept of ecological regionalization through to the the ecological evaluation, highway design, and the ecological restoration and reconstruction, Proposed a way for the integration of ecological Regionalization and Ecological Protection, to guide highway ecological design and management.
