| 摘 要： | 本文利用2002年的ETM＋图像和该地区1：25万DEM数据，采用计算机图像处理和目视解译相结合的方法，辅以野外实测数据、历史资料进行综合分析，对该地区河道的演变特征和新构造进行详细解译。基本查清了新近系以来该地区河道的发展演变历程，岷江和青衣江都存在很大幅度的河道迁移现象，综合研究发现，河道迁移与该地区新构造运动密切相关。

| Abstract: | Based on the visual interpretation and computer image processing combined with the multiaspect data including remote sensing image and digital elevation model of the studied area （in 2000） and field investigation, authors studied and analyzed the stream channel transition and neotectonics. It is found that the Minjiang river and Qinyijiang river in the southern Chengdu basin underwent a wide-range stream channel transition since Neogene. The comprehensive study of ancient stream channels revealed the close relation between channel transition and neotectonics of the area. |
