摘 要:黄河中游多沙粗沙区,特别是粗泥沙集中来源区的水土流失是黄河泥沙,特别是粗泥沙的主要来源,强化对该区的治理是减少入黄泥沙,特别是粗泥沙,效果最为明显,通过综合治理,在减少入黄泥沙的同时,也必然要减少入黄水量。但应看到,因减少了入黄泥沙,特别是粗泥沙,也会减轻下游河床淤积,因而减少了为维持下游"河床不抬高"而消耗的输沙用水量。研究表明,多沙粗沙区,特别是粗泥沙集中来源区治理程度越高,所节约的输沙水也越多。可以说,加强该区治理,可间接为黄河"增加"水资源。The soil and water loss in sediment-laden and coarse sand area in the middle Yellow River,especially in the coarse sand concentrated source region is the main source of the sand especially coarse sand of Yellow River.Strengthen the controlling of this area can obviously reduce the sand especially coarse sand into Yellow River,while reducing the water quantity into Yellow River at the same time.But it is clear that the sediment transport water consumption which in order to maintain "no riverbed elevation" is reduced as siltation reducing in the lower reaches because reduced coarse sand into Yellow River.The research showed that the higher the level of controlling,the sediment transport conservation of water is much more in sediment-laden and coarse sand area especially coarse sand concentrated source region.So strengthen the controlling in this area can increase the water resource of Yellow River.
关 键 词:多沙粗沙区 粗泥沙集中来源区 治理 减沙 增水 黄河
