黄河下游引水引沙与河道冲淤关系研究综述

Review of studies on relation between channel silting and water diversion of the Lower Yellow River

自１９６０年起，黄河引水对河道的淤积就受到有关部门的关注，引水引沙与河道冲淤关系的研究对黄河来说是非常重要的．近年来，一些学者对这方面的问题进行了研究，提出了增减淤临界分流比曲线，最大增淤比曲线等．本文总结分析了这些研究成果，对减少黄河下游河道淤积，提出合理的引水引沙方案具有重要的参考价值．

Since 1960,the channel deposition caused by water diversion in the Yellow River has been paid attention to.Recently,some scholars studied the relation between water diversion and sediment deposition in the main channel of the Lower Yellow River,and offered the curve of critical diversion ratio when the deposition is minimum and the curve of maximum ratio of deposition increment,etc.This paper analyses and summaries these results,and suggests the reasonable scheme of water diversion in order to reduce the channel deposition of the Lower Yellow River.
