In the northeastern irrigation area ofulanbuh Desert,the multi-sources water exists and the supply and demand amounts are relative to the channeled Yellow River amount. For these characteristics,three schemes of the high,medium and low channeled Yellow River amount were determined for the planning 2010 year. The supply and demand amounts of water resources were then analy zed in the Northeastern irrigation area of Desert. On the basis of these works,the water resource balance index for three schemes and three subindliex carrying caparity of oasis scale and population and per capita GDP were alculated.Through these indices,the carrying capaccity of water resource in northeastern irrigation area ofulanbuh Desert was set forth synthetically.
