摘　　要：对梨园水电站降雨及入出库流量变化趋势进行了分析,并对其水电站径流过程进行分析和模拟。结果表明,梨园水电站来水受上游融雪影响,每年3-5月融雪径流和地下径流是梨园流域的主要来水补给项,6-10月降雨径流是梨园流域主要来水补给项。明晰流域来水机理,选取合适的径流预报模型并率定敏感性参数可提高水电站来水预测准确性,为进一步优化调度方案提供数据支撑。An analysis of the rainfall,reservoir inflow and outflow variations of Liyuan Hydropower Station reveals important insights into the runoff process of the station.The results indicate that the inflow to the Liyuan Hydropower Station in Yunnan is influenced by upstream snow melting.During the months of March to May,snow-melting runoff and underground runoff are the primary sources of inflow recharge in the Liyuan Basin,while rainfall runoff from June to October becomes the main inflow recharge component.It is important to understand the reservoir inflow mechanism in the basin,select an appropriate runoff prediction model and determine the sensitivity parameters.By doing so,we can improve the accuracy of reservoir inflow prediction for hydropower stations and obtain valuable data support for further optimization of scheduling schemes.
