摘　　要：南水北调中线工程——丹江口水库加高工程完工后,水库采取不完全多年调节,进入水库的大部分泥沙将淤积在库区内,从而影响水库综合效益发挥和使用寿命。在大量实测资料分析的基础上,从尽量减少丹江口水库泥沙淤积、改善淤积分布,减轻坝下游河床冲刷及其所带来的不利影响等方面,对丹江口水库进行泥沙调度的必要性和可行性进行了研究和探讨,提出了丹江口水库泥沙调度的方式,可为下一步优化水库运行调度方式提供参考。Incomplete yearly regulation will be adopted for Danjiangkou Reservoir after completion of the dam heightening pro ject for South North Water Diversion, and the water level in front of the dam will rise, resulting in sediment deposition in the reservoir and further influencing the comprehensive benefits and the service life of the reservoir. Based on the analysis of a great deal of measured data, the necessity and feasibility of sediment regulation for the reservoir are researched from the aspects of re ducing reservoir sediment deposition, improving deposition distribution, alleviating scouring of the downstream river channel and its unfavorable influence etc. and the sediment regulation mode of the reservoir is suggested.
