根据位山灌区西沉沙地泥沙清淤观测资料，总结了不同时期的灌区泥沙处理特点，比较了传统清淤与输沙通道改造的泥沙处理费用的差别，分析了输沙通道改造后渠道输水输沙能力的差异。结果表明，在新的水沙条件下输沙通道改造能有效减轻沉沙池的泥沙淤积，延长沉沙池的使用年限，同时实现灌区泥沙远距离输送、分散沉沙的目的，减淤效果明显。

In recent years,Weishan irrigation area was exploring the application of sediment transportation channel methods to reduce sediment treating burden step to adapt the new condition after the operation of Xiaolangdi Reservoir to fulfill the inter-provincial water transfer tasks and im-proving the sediment transport environment. Based on the dredging data from Weishan irrigation area,the characters of sedimnet treatment between several periods were summarized. It observed and analyzed systematically the traditional dredging methods and the effect of the channel sediment transportation application. The results show that the traditional dredging way is conservative,with large impact on environment and heavy sediment treating burden. But with the channel sediment transportation way,we can use the sand basin for a long time,with less sediment deposited. As a whole,it has very obvious effect in reducing sediment.
