The Change of Underground Water in Jingta Yuanyiangchi Irrigation Area and its Influence on the Environment

Jinta Basin lies in the serious desertification area of Hexi Corridor, Gansu. Irrational utilization of water resources in this area will sharpen the process of desertification,therefore, rational develoment and utilization, of water resources is one of the key points for the further developmnt of local agricultural production and environmental protection. The author suggests that an overall plan and directional control made through taking the basin as the control unit, insisting the combination of increasing "water resources weih decreasing water resources, that is, developing simultaneously wwater store, water irrigation, drainage and water supply",the problems concerning mountains, rivers, farmland,forests and roads should be tackled in a comprehensive way, and the development and utilization of surface water and underground water should be managed unitedly, the system of oasis protection should be built for the purpose of developing efficient, steady and agricuural ecological oases.
