As a basic premise of the Development of the West Regions, the scale of the transportation construction will be largely extended in Xinjiang in the relatively long time.Large-scale highway construction inevitably leads to some negative impacts on environment.It is a big task to effectively deal with the relationship between highway con-struction and ecological conservation and environmental protection.Based on the retrospection appraisal of the effect of the environment protective measures in highway construction in Xinjiang during the past 20 years, this paper dis-cusses the environmental impacts of highway construction and the subsistent issues of highway environmental impact assessment and environment protection management.The impacts of highway construction to environment are differ-ent from different time.During highway construction period, the main impact and destruction to environment are to occupy and divide up large area of land sources and land use change.In highway operation, a highway divides up the biological habitats.Furthermore, exhaust emission and noise are also harmful to environment.This paper analy-zes the applicability of ecological conservation measures, wind erosion control measures and desertification preven-ting measures.The paper focuses mainly on the environmental issues related to the highways in Xinjiang during the construction period.Temporary road construction and destroyed areas for highway construction result in some seri-ous impacts on environment, such as desertification and soil erosion, so it is necessary to positively take some measures for soil and water conservation.Some appropriate suggestions are also put forward for monitoring and pro-tecting environment during highway construction.
