摘　　要：根据三门峡水库蓄清排浑运用以来库区非汛期蓄水淤积、汛期降低水位冲刷的特点,分析了水库的造床期与造床流量,结果表明：①三门峡水库汛期除滞洪期以外均为造床期,三门峡站多年平均第一造床流量小于潼关站,第二造床流量与潼关站相近,河宽调整与包括当年在内的前4~5年加权平均造床流量的相关性最好;②三门峡库区存在高滩、低滩和主槽河底3个层面的纵剖面,2006年汛后三者的比降分别为1.2、1.9和2.3。The paper analyzes the period of channel-forming and formative discharge of Sanmenxia Reservoir according to the characteristics of storage and deposition in non-flood season and water lowering for scour in flood season since adopting the operational principle of storing clear water and releasing the mud.The outcomes show that a) the flood season of the reservoir is the period of channel-forming except the period of retardation.The first formative discharge of normal annual of Sanmenxia Station is smaller than that of Tongguan Station,the second formative discharge is close to Tongguan Station and the relativity of river width regulation and the weighted average formative discharge of early 4-5 years including the same year is the best.b) The reservoir area has three longitudinal profiles of high beach,low beach and bottom of main channel.The slope is 1.2,1.9 and 2.3 respectively after 2006 flood.
