摘　　要：在以往输沙水量研究成果的基础上,从输沙机理分析着手,根据1951—2009年黄河下游河道实测水沙资料,在剖析上游水沙特点和沿程泥沙冲淤关系的基础上,预估了经历小北干流放淤和三门峡、小浪底水库联合调度后,连续枯水状态下的黄河下游输沙水量。结果表明:①按照枯水年考虑,2015年黄河下游输沙水量至少需要127亿m3;②小浪底水库达到冲淤平衡后,上游全部来沙将于2020年进入黄河下游河道,2020年枯水年情况下需要的输沙水量至少为139.8亿m3;③按照持续枯水情况考虑,2030年下游河道需求的输沙水量至少为104亿m3,与2008年相比,至少缺水74亿m3,南水北调西线工程建设势在必行。Based on the achievements of sediment transport of the previous study,the water volume for the sediment transport of the lower Yellow River was forecasted which can be applied to the long-term low water condition in this paper,according to the data collected at several stations during 1951-2009,based on the anciently production of the water volume for the sediment transport,the characters of the upstream water and sediment and the relation with processing scour or silt,which experienced after warping of the Xiaobeiganliu and the joint regulation of,Sanmenxia and,Xiaolangdi Reservoirs.The paper shows that a） considered as a low water year,the water used for the sediment transport of the Yellow River needs 12.7 billion m3 in 2015 at least;b） all the upstream sediment will come into the lower Yellow River in 2020,when the balance occurred in the Xiaolangdi Project,needs 13.98 billion m3;c） considered as continuous low water condition,water volume for the sediment transport of the Yellow River need 10.4 billion m3 at least in 2030,compared with 2008,lack volume will arrived 7.4 billion m3 at least,then the West Route of South to North water Transfer Project is imperative.
