基于浅地层剖面探测的近代黄河尾闾流路变迁研究初探
|
摘要
黄河尾闾流路具有变迁频繁的特点,1855年以来黄河尾闾小规模的改道50多次,较大规模的改道10余次,平均约10年就改道一次.依据浅部地层剖面的结构及形态特征,以及河流相砂的沉积特征,对黄河三角洲近岸海域两千余公里的浅部地层剖面探测数据资料进行以埋藏古河道为主的灾害地质类型的解译辨识,初步建立黄河尾闾流路变迁过程图.结果表明基于浅地层剖面探测的黄河尾闾流路变迁研究是可行的.研究结果与前人有关的黄河尾闾流路变迁研究结果较吻合,基本反映了近代黄河尾闾流路的变迁过程,研究从浅地层剖面探测探讨近代黄河尾闾流路的变化过程,不仅丰富了古河道理论研究,同时对于黄河三角洲发育演变过程,尤其是近代黄河尾闾流路变迁研究具有十分重要的意义.
The Tail flow-path changes of the Yellow River are frequent Since 1855,the small-scale changes have 50times as large-scale more than 10 times,with an average of about 10 years.Based on the morphological characteristics of sub-bottom profile,as well as fluvial sand sedimentary characteristics,more than 2000km subbottom data are interpreted,and the change diagram are took.Research results basically reflects the flow-path change process,the changes show that the probe from the perspective of sub-bottom profile is feasible.The study is exploratory to detection angle of the change process of the modern Yellow River Tail of the flow path from subbottom profile.That not only enrich the theoretical study of the ancient river,but also the evolution of the Yellow River Delta development,especially the recent Yellow Tail flow path changes has great significance.
