Regeneration and Rehabilitation of the Vegetation along the High-grade Highways in Xinjiang

As the natural conditions of Xinjiang are not so good and the ecological environment is vulnerable, the protection of the eco-environment, regeneration and rehabilitation of the vegetation destroyed in the processes of highway construction and transportation are the issues that the governments and the constructors pay attention to. This paper analyzes the characteristics of the natural environment, the factors impacting the natural regeneration of the vegetation and the ecological structure and functions in the areas along the high-grade highways in Xinjiang based on the investigation about the present situation of the vegetation and the growing environment of plants and on the measurements of the snowcover accumulation and melt, the disturbed soil and its physical-chemical properties. The ecological areas along the high-grade highways in Xinjiang are divided. Some artificial assistant measures to regenerate and rehabilitate the vegetation along the high-grade highways in Xinjiang are suggested.
