On the basis of discussing new schemes, location, and affected regions of west route water transfer project, the authors of this paper dealt with main environment impact on the water exportry region of west route water transfer project, including two aspects of natural environment and social environment, such as the influences on climate, animal and plant, water quality, reservoir area and its circumjacent geologic environment, public healthy etc, and the reservoir submerging influences on social economic. The main conclusions relate to 4 aspects: ① The influences on air temperature and precipitation of the reservoir and near dam sections are all Small. The precipitation contribute ration to some areas is 0 004~0 008 as a result of the reservoir section evaporation increase. Though the drought river valley is affected, the influence is slight. ② The influences on biology are mainly showed in the aspects of fishing section series composition and community structure. It would also cause the decrease in the amount of terraneous biology, but the biology species resources would not lessen. ③ It would lower the water quality of dam backward position, but the influence is limited because the population density is sparse and the pollution is not severe. ④ Submerging losing is small, emigration is small too. Accordingly, the present paper also provided some references for the study of west route water project's influence on environment.
