如何科学合理地确定水库蓄水期起始时间对保证水库正常运行、下游灌溉、供水、河道生态需水等方面有重要的作用,尤其是以冰川积雪融水补给为主的河流水库。而目前在实际水库运行中也没有一个较好的合理确定标准和方法,只能根据流域特性水库运行管理人员主观确定,受人为因素影响较大,增加了水库正常运行的不确定性,不能充分发挥水库各方面的效益。因此提出在以MOD IS积雪监测数据基础上结合零度层高度监测数据即雪线高度合理确定水库蓄水期起始时间的方法,更具有说服力及合理性,对水库运行管理提供了一定的指导依据,有利于当地水资源的合理利用,并通过实际应用说明方法是可行的。
How to determine the starting time of reservoir storage period scientifically and reasonably plays an important role in ensuring the normal operation of reservoirs, downstream irrigation, water supply and ecological water demand of rivers, especially the river reservoirs that rely mainly on glacial snowmelt recharge. At present, there is not a good and reasonable standard and method for determining the actual reservoir operation, which can only be determined subjectively by the reservoir operation and management personnel of the river basin characteristics. It is greatly affected by human factors and increases the uncertainty of normal operation of the reservoir and can not be sufficient Play all aspects of the reservoir benefits. Therefore, it is more convincing and reasonable to combine the MODIS snow monitoring data with the monitoring data of zero-degree altitude, ie, the height of snow line to determine the initial time of reservoir storage period, and provide some guidance to reservoir operation and management Based on this, it is conducive to the rational utilization of local water resources and is feasible through the practical application of the method.
