小浪底水库是确保黄河下游防洪、减淤的关键性工程,2007年已进入拦沙后期。为了尽可能地延长水库的使用寿命和减少下游河道的淤积,以最大限度地发挥小浪底水库的作用,制定合理的水库运用方式是非常重要的。回顾了小浪底水库运用以来的贡献和新情况,评述了拟定的水库运用方式的研究成果,根据三门峡水库和黄河下游河道数十年来的冲淤变化的实践经验,提出了小浪底水库拦沙后期运用方式的原则和水沙调控的建议。
Xiaolangdi Reservoir is to ensure that the lower reaches of the Yellow River flood control, sedimentation reduction of key projects, in 2007 has entered the sediment recovery. In order to prolong the service life of reservoirs as much as possible and reduce the siltation of downstream rivers, it is very important to formulate reasonable reservoir operation ways in order to maximize the effect of Xiaolangdi Reservoir. After reviewing the contribution and new situation since the Xiaolangdi Reservoir was used, the research results of the proposed reservoir operation mode were reviewed. According to the practical experience of erosion and deposition in the Sanmenxia Reservoir and the lower Yellow River for decades, the late-stage sedimentation mode of Xiaolangdi Reservoir The principle and the regulation of water and sediment.
