根据1959-2000年青海湖流域水文观测资料，研究了近40年来青海湖流域降水、径流、蒸发量、湖水位及地下水补给的动态变化。据估计，1959-2000年期间出现了3.32米的降水量，导致年降水量为3.60108立方米。并讨论了维持生态平衡和社会经济可持续发展所需的跨流域引水量，年引水量为4.1108m~3即可满足水资源优化配置的需要。
On the basis of the observed hydrological data in Qinghai Lake Basin, 1959-2000, we studied the dynamic changes of precipitation, runoff, evaporation, lake water level and the supplement of ground water of Qinghai Lake for the past forty years. Estimates revealed that a 3.32m-drop occurred during 1959-2000,resulting an annual decrease of water quantity of 3.60108m3 . Moreover, the amount of interbasin diversion required for maintaining ecologic balance and social economic sustainable development was discussed, an annual quantity of 4.1108m3 could meet the needs for water resources allocation optimization.
