摘　　要：水库淤积平衡问题对于确定淤积危害程度、可持续利用标准等都非常重要。本文通过分析大量已建、在建和规划水库淤积情况,对水库淤积初步平衡后淤积变化趋势与设计淤积标准等问题进行了讨论和商榷。研究表明,水库淤积初步平衡后,兴利库容淤积发展仍然很快,库尾河床与水位抬升仍在继续,并未最终稳定。水库淤积平衡应该更加注重兴利库容淤积情况和库尾河床与水位抬升趋势,仅仅关注总淤积量变化情况是不够的。从区域长远利益考虑,大江大河上的水库设计淤积年限还应大大加长。By comparing the accumulated sedimentation volume and effective sedimentation volume in various reservoirs in different periods, the sedimentation tendency after preliminary equilibrium and sedimentation design life were discussed. The authors proposed that more attention should be put on the sedimentation in effective volume and the raising tendency of both the riverbed and the water level in the reservoir tail region instead of merely consideration of the accumulated sedimentation volume. This work also proposed that for the long term use of the reservoir, the sedimentation design life should be greatly prolonged in those reservoirs built on the sediment-laden rivers.
