Research on the impact of climate warming on water resources for oases of Northwestern China will provide a scientific basis for easing water use conflict. Combined with the collection of the Kaidu runoff, the meteorological data, water use of various industries in Heshuo, Hejing and Yanqi Counties in 1961-2011, the impact of climate warming on surface water availability and demands was explored. The results showed that: (1) Surface water availability will not increase significantly along with the rising in temperature, but agriculture, residence and ecological water demands will increase significantly. (2) The total water demands will increase at a rate of 80 million m(3) (0.5 degrees C)(-1). (3) Inflow from the mountains cannot meet water demands when the temperature continues to rise from 9.43 degrees C. (4) For easing the water use conflict in the oasis, we should take measures to reduce the greenhouse gas emissions and control the rise of temperature.
