Abstract:
The shaft irrigation and drainage project in Aksu area of Wushi County,Xinjiang is a newly-built project in the Aksu River basin according to The Short-Range Comprehensive Planning Report in the Ta Limu River and Implementing Scheme of Water-Saving and Innovation Works in the Aksu River Basin Irrigated Area in Five Years,which have been approved by the State Council of China.The implementation of the project will bring certain influence to the Qiugeer irrigated area in Wushi County.Based on a systematic analysis of current regional environmental state of the project,the authors studied the environmental effects to the irrigated area after implementation of the project,from aspects of project construction,water resource utilization,groundwater level,soil salinization,and social environment.It was augmented that the shaft irrigation and drainage project will not cause heavy influence to the environment in the irrigated area,and will not affect the utilization of the groundwater resources;otherwise,it may develop in a favorable direction.It will not cause continuous decline of the water table in the irrigated area,and even the exhaustion of the groundwater resources.The implementation of the project will help solve the problem of soil salinization in the irrigated area.The irrigation benefit from the project will reach 5.452 2 million yuan.Finally,suggestions for the sustainable development of the irrigated area are put forward.
