中文摘要：

在充分收集相关资料的基础上研究了青海湖1960—2000年间降水、蒸发、径流等要素的变化趋势，根据水量平衡方程估算每年的湖泊水量并作出误差分析，在已有的青海湖水量平衡研究基础上重新建立了湖泊水量与降水及径流等要素的线性回归关系，讨论了夏季降雨对青海湖水量平衡的影响。

英文摘要：

On the basis of the collected hydrological data from 1960-2000 in Qinghai Lake,we studied the changing tendency of precipitation, evaporation and runoff, estimated the annual lake volume by using the water balance equation and analysed the error. On the basis of the water balance research, the linear regression relations between precipitation, runoff and the water volume were reconstructed and the influence of summer monsoon variability on the water balance of Qinghai Lake was discussed.
