摘　　要：针对我国西北地区高含沙水流的形成原因以及库内水沙运动的特点,对高含沙地区中小水库淤积现状及水库淤积形态进行了分析,提出了减少中小水库淤积的基本措施,即加强流域水土保持治理是防止淤积的根本办法、设排沙底洞是减淤的辅助措施、汛期采用异重流排沙是减淤的关键。According to the features of hyper-concentration flow mechanism in Northwest China, the status of sediment of small and medium reservoirs and their patterns were analyzed, some basic measures for mitigate reservoir sediment were put forward. The key measures were those of harnessing soil and water loss, setting sediment discharge tunnel, and adopting operation mode of discharge sediment by density flow.
