摘要
对以冰川积雪融水补给为主的河流而言,水库蓄水期起始时间的判定对水库的正常运行起较重要的作用。在水库实际运行中何时开始水库蓄水并没有一个合理的确定标准,水库运行管理人员只能根据流域特性主观确定,受人为因素影响较大。借助RS和GIS以及数字高程数据(DEM)分析了研究区2005年各个时期各个高程带的积雪覆盖率变化。通过比较分析确定了研究区较合理的水库蓄水期起始时间,为今后水库运行管理提供了一个参考依据。
The starting time judgment of the storage period plays an important role in normal operation of reservoir which are mainly recharged by glaciers and snow meltwater rivers. There are no one reasonable determination standards to judge the starting time in actual operation of reservoir, which can only be determined subjectively by operation and management staff of reservoir according to basin characteristics and the actual experience. By using RS, GIS and DEM, the change of snow cover rate was analyzed in various period in different elevation scopes of the study area. After comparison, the more reasonable starting time was determined.
