Water is the core of the existence and the development of oasis,so arid oasis stability is closely related with water resources.According to data from 2000 to 2009,comprehensive 10-year average water demand is estimated using the methods of evaporation coefficient and quota for various natural ecosystem and social economic system in oasis of Kaidu-Kongque River basin,and oasis stability is discussed under the water resources constraint conditions.The results indicate that: 1) During the period of 2000 to 2009,the theoretical value of annual average water demand for oasis was about 54.80×10^8m^3,of which 20.55×10^8m^3 is in Kaidu River basin,21.90×10^8m^3 is in Kongque River basin and 12.35×10^8m^3 is in Bosten Lake,respectively.Compared with 10-year average water supply,one can see that there is a great imbalance between supply and demand of water.2) Oasis area supported by water resources is approximately 3 139.66 km^2(excluding Bosten Lake area),there into,the area for irrigated agriculture is about 1 395.41 km^2.Oasis area supported by water resources is less than actually developing area(5 248 km^2),which means that oasis is in unstable state and that the current oasis area should be properly drawn back.At last,the lowest ecological water level of Bosten Lake is preliminarily discussed,and altitude of 1 045 m is regarded as the lowest water level for the large lake,and that 1046.5 m is regarded as the lowest water level for the small lake.
