Study Of Highway Domain System Evaluation Based On The Highway Division

As a long-distance, large-scale artificial landscape, the road's building promotes the development of China's rapid economic development, but also the ecological environment has brought greater pressure, not only changed the ecological environment of the region, but also changed the original landscape structure, change the logistics, energy flow and the flow of information transmission and access, and the road surrounding the region form a complex artificial and natural ecosystems - highway domain ecosystems. At present, the road evaluation of the ecological environment are mostly focused on the study of highway construction on the impact of the ecological environment, the evaluation of qualitative mainly to the general, difficult to grasp the scientific system, and to guide the latter part of the construction and operation of ecological and environmental protection work. In view of the domestic high-speed environmental problems have become increasingly prominent in our country, this paper studies the highway research Domain ecosystem evaluation based on the ecological zoningThis paper based on the Highway domain of the concept of eco-systems, analysis of the way domain ecosystem composition, functions and characteristics. In introducing the concept of ecological zoning, the Highway Division domain system for the evaluation and risk analysis system provides the necessary basis and prerequisite for final use of the health system of evaluation and risk assessment system theory and methods, built a road ecological domain Systematic evaluation of the ideas and methods, and used in practice for highway construction ecological restoration and post-Operation and Management provides a basis for guiding.In this paper, the Ministry of western technology, "the Qinling mountain highway construction ecological protection technology" issue as an example to support the Xihan highway (huyang departs) as the main road domain research, analysis Expressway in the region of interference on highway construction Road domain system on the environmental impacts and evaluation system adopted by the Xihan Dynasty that the sub-regional highway system status.
