摘要
引水引沙对河道冲淤的影响，与原河段的冲淤情况，引水的分流比、分沙比及河道特性等有关。黄河上游是水量的主要来源区，来水含沙量低，引水对下游河道冲淤的影响较大；中游为多沙区，中游引水对中下游影响较小；下游为多口门引水，引水对本河段影响也较小。
The influence of water and sediment irrigation on the river channel siltation and erosionis related to the original river siltation and erosion situation,the ratio of the water irrigation andsediment diversion,and river channel characteristics,and others. The upper reaches are the majorwater source with low sediment content and evident influence by water irrigation;as a sedimentconcentrated region,the middle reaches are with slight impact from water irrigation;in the lowerreaches,because there are lots of irrigation gates,the influence from water irrigation is little aswell.
