摘　　要：河流古流速、流量的估算，可以反映出古河道的冲刷与沉积的演变过程．通过对古流量进行研究将为深入理解过去气候变化、讨论人类与环境变化的互动关系以及环境因素在文明形成中的作用都具有重要的意义．笔者对河流古流量研究状况进行了综述，多数学者主要用河相关系法、地貌-水力学法、泥沙粒径-水力学法、古水系法等对占流量进行估算，并指出了目前研究的不足和发展趋势，以利于研究者把握古流量研究现状，并推动其进一步探讨．Paleo-velocity and flow of the fiver can reflect the evolution process of the Paleochannel＇ erosion and deposition. The research of paleo-flow will carry a lot bearings on the in-depth understanding of the climate change in the past, exploring the interaction between human beings and environmental changes, and the role of environmental factors plays in the forming of civilization. This article makes a comprehensive analysis as to the status quo of river＇ s paleo-flow, most scholars study paleo-flow by ways such as the hydraulic geometry method, the gemorphology- hydraulics method, the sediment particle size-hydraulics method, the paleo-water system method and so on. Furthermore, it also indicates the deficiency and developing trend of current research in order that the reseachers know clearly the current research status of oaleo-flow, thus oromotinz luther exnloration in this ar^a.
