摘　　要：随着水资源开发利用强度的持续加大,岳城水库面临着蓄水量和生物多样性减少等问题。为维护库区水生态系统平衡,充分发挥防洪、灌溉、供水和生态调节等综合效益,基于岳城水库(坝上站)1969—2022年实测逐日水位数据,采用最低年平均水位法、年保证率设定法和生物最小空间需求法3种方法,计算得到岳城水库最低生态水位127.80 m。通过合理性分析,该水位确定是合理的,可为岳城水库防洪减灾、水资源管理和保护以及优化调水等提供技术支撑。With the continuous increase in the intensity of water resource development and utilization,Yuecheng Reservoir is facing problems such as reduced storage capacity and biodiversity.In order to maintain the balance of the water ecosystem in the reservoir area,fully utilize the comprehensive benefits of flood control,irrigation,water supply,and ecological regulation,based on the daily water level data measured at the Yuecheng Reservoir(Bashang)Station from 1969 to 2022.Three methods are adopted:the lowest annual average water level method,the annual guarantee rate setting method,and the minimum biological spatial demand method.The minimum ecological water level of 127.80 m in Yuecheng Reservoir was obtained.Through rationality analysis,the determination of this water level is reasonable and can provide technical support for flood control and disaster reduction,water resource management and protection,and optimization of water diversion in Yuecheng Reservoir.
