摘要:: 通过对近年来金沙江云南段考察研究获得的地貌、湖盆和环境效应记录的总结和梳理,并结合前人研究成果,建立了金沙江河谷-水系形成演化的年代框架,认为金沙江河谷-水系的演化历史可以分为3个阶段,即上新世-早更新世初的孕育阶段、早更新世末-中更新世的发展阶段和晚更新世的定型阶段。现代金沙江河谷-水系的地貌格局以及干热河谷的景观雏形都形成于早更新世末。

Abstract:: On the basis of our new geomorphologic, lacustrine and environmental feedback records and a reassessment of published date, the chronological framework of the evolution of Jinsha River valley drainage is reconstructed. We suggest that the history of the Jinsha River valley drainage formation can be divided into 3 stages, namely embryonic stage (from the Pliocene to Early Pleistocene), initial development stage (from the end of Early Pleistocene to Middle Pleistocene) and shaping stage (later Pleistocene), and also propose the landforms pattern of Jinsha River including Dryhot Valley should appear around the end of Early Pleistocene.
