本文阐述了溯源淤积和侵蚀基准面的概念。根据河流沉积的地貌形态、泥沙结构的沿程变化关系、矿物的百分含量的沿程变化和水文特性等要素,论证了黄河下游高潮线以上泥沙的淤积形式为沿程淤积,高潮线以下理论上存在溯源淤积,但实际上没有反映。 This article describes the concepts of source-sedimentation and erosion datum. According to the morphological features of river sediments, the relationship between the sediment structure along the course, the change of mineral content along the course and the hydrological characteristics, it is demonstrated that the sediment deposition above the high reaches of the Yellow River is sedimentation along the process, The following theoretical existence of sedimentation, but in fact did not reflect.
