摘要
在遥感调查和监测的基础上,结合第四纪地质资料,对黄河银川平原段的河道演变过程进行了系统研究,对主要的河流改道原因进行了分析。研究表明:黄河银川平原段在早更新世初期形成,此后,自西向东不断迁移;在中晚更新世发展壮大,到全新世形成了银川平原的主体,并留下了明显的古河道遗迹;到了现代,河道逐步变窄,向东迁移的趋势未变且速度依然很快。
Based thors studied and on remote sensing monitoring and investigation combined with data of Quaternary geology, the auanalyzed the change process of the Yellow River course in Yinchuan plain sector. It is found that the Yellow River in Yinchuan plain sector was formed in Early Pleistocene and the river course frequently moved eastward after that. In Middle and Late Pleistocene, the river course grew remarkably. In Holocene, the sediments of the Yellow River formed the main body of the Yinchuan plain, with several old river courses left on it. In recent years, the river course has become increasingly narrower and remained shifting eastward.
