黄河下游纵向不均衡调整现象研究进展与展望
Research Progress and Prospect of River Longitudinal Non-Equilibrium Adjustment in the Lower Yellow River
摘要
Abstract
There exists significant longitudinal nonequilibrium adjustment phenomenon in the lower Yellow River,which is the uneven distri-bution of erosion and sedimentation along the river and adjustment of vertical slope.The research on the nonequilibrium adjustment phenome-non is a cutting-edge issue in the riverbed evolution.Studying and solving this issue not only has great scientific significance,but also has great practical application value in restraining the rise of the riverbed in the lower Yellow River and ensuring the safety of flood control.This study summarized the various types of nonequilibrium adjustment phenomena,reviewed the research progress on longitudinal nonequilibrium adjustment and"hump"phenomena in the lower Yellow River,and expounded the basic sediment science issues involved.At present,there is a lack of clear understanding of the formation mechanism of longitudinal nonequilibrium adjustment in the lower Yellow River,and the im-pact of terrain is not yet clear.The impact of upstream and downstream erosion and deposition cannot be distinguished,and the impact of ero-sion basis cannot be quantified.The study of the"hump"phenomenon is still mainly based on data analysis,and there is still a lack of deep understanding of the migration law,response mechanism and future evolution trend of the"hump"reach.关键词
