摘　　要：新疆玛纳斯河平原带位于北天山山前褶皱低山丘陵与冲积扇带的北部,准噶尔盆地中央。根据钻孔剖面资料研究该区第四纪地层在水平和垂向上的变化规律,结合山前褶皱丘陵与洪积扇的演化历史,探讨了平原曲流带的演化过程。结果表明:平原带的演化受山麓带范围向北扩张和沉降中心向北迁移的影响,所以平原曲流带向北推进10～30km。The Manas River is the largest river in the north margin of the Tianshan Mountains in Xinjiang.Plain zone of Manas river is located on the north of folded hills and alluvial fans of Tianshan Mountains.It is also in the middle of the Zhungaer Baisn.Based on the boreholes data,the law of Quaternary strata in horizontal direction and vertical direction was studied.Combined with folded hills and alluvial fans evolution history,the history of plain and meander channel zone of Manas river was discussed.The results indicated that the history of plain and meander channel zone of Manas river is mainly affected by the folded hills extending and subsidence centers moving towards north about 10~30km.
