摘　　要：结合黄河上游龙羊峡、李家峡、公伯峡水库运行期水库水温实测资料,分析了龙羊峡水库单库蓄水运行和大型梯级水库联合运行后对下游河道水温的影响,对多年调节型水库和坝高大于100 m的日调节水库对下游河道水温的调节作用进行了分析总结,对高坝大库水库水温分析具有一定参考价值。Combining the data of the water temperature measured during the operation of the Longyangxia,Lijiaxia and Gongboxia reservoirs in the upper reaches of the Yellow River,this paper analyzes the impact of the single storage operation of the Longyangxia Reservoir and the combined operation of large-scale cascade reservoirs on the water temperature of the downstream river.The paper analyzes and summarizes the regulating effect of the multi-year regulating reservoir and daily regulating reservoir with a dam height over 100 m on the downstream river water temperature,which has certain reference value for the water temperature analysis of high dam reservoirs.
