Abstract: This paper mainly discusses the features of physical geographic environment, water resources and their development and use at the south edge of Taklimakan Desert, and reveals the obviously negative effect on oasis eco-environment. The environmental deterioration at the ecological fragile zone resulted from the impact of climatic change and human activities since 1900, especially in the recent 50 years, is extremely disadvantageous to the sustainable development of the region. Therefore, it is necessary to adjust the allocation and optimize the utilization of water resources, to pay equal attention to the protection and the development of natural and artificial oases, and then to gradually restore the balance between water and ecology of natural oasis. Only the serious status of eco-environment deterioration be controlled and desertification disaster be prevented, can the regional environment run into health circulation.

Key words: development of water resources, oasis, effect on eco-environment, the south edge of Taklimakan Desert
