| 摘 要： | 通过对金沙江雅砻江河口-金坪子段的地貌、沉积和年代学的研究,结合区域地貌和新生代沉积,初步认为该区域河流发育经历了4个阶段:高原面解体河流发育期(7 ～4.2Ma)、高原湖泊和盆地形成期(4.2～1.1Ma)、古雅砻江和古金沙江期(1.1～0.73 Ma)和金沙江贯通东流期(0.73 Ma至今).7～ 4.2Ma,高原... |

| Abstract: | Based on the study of the fluvial geomorphology along the Jinsha river from the estuary of Yalongjiang to Jinpingzi by using the methods of sedimentology,geomorphology and chronology,combining with the character of geomorphology and the Cenozoic sediment in this region,we suggest that the development of reach can be divided into four stages,i.e,1) the river developing on the plateau(7-4.2 Ma),2) the lake and basin developing on plateau(4.2-1.1 Ma),3) the ancient water system developing(1.1-0.73 Ma),and 4) t... |
| Keywords: | Jinsha River fluvial geomorphology Cenozoic sediments run-through headward erosion |
