Frequent swings and diversions of old channels in lower reaches coexist with the multi-phase overlapping of Yellow River sub-delta lobes. In addition, sedimentary bodies of sub-delta lobes during various developmental stages are known to have undergone overlapping with one another. Experimental analyses of 24 short-column (length of less than 1 m) stations were examined. In addition, due to the influencing effects of swinging of old channels in the Yellow River’s lower reaches, sub-delta lobes of the different historical periods were in different evolution stages, including erosion and degradation(Diaokou), scouring and silting balance(Qingshuigou, and Shenxiangou sub-deltas), and sedimentation (current estuary sub-delta). The characteristics of sedimentary bodies, along with scouring and silting of the seabed, were found to have impacts on the sedimentary characteristics of the sub-delta lobes. The sedimentary bodies of the Yellow River Delta (YRD) were divided into three types, after cluster analysis had been completed. Type-I was dominated by the current estuary sub-delta. Their grain-size frequency distribution curves were with an average grain size of 4.43$\phi$, and characterized by moderate sorting, thus indicating that the sediment supply of the Yellow River was the main source, while a trend of sea continuously receiving the continental source supply and silt existed. The sand content of Type-II was significantly higher than that of type I, and its sand composition was greater than 40%. In addition, the frequency accumulation curves were either bimodal or multimodal, with poor sorting. The area was formed by severe erosion and transformation of the original sediment. The long-probability curve of Type-III area was mainly unimodal. The average grain size fluctuated at approximately 5.26$\phi$, with poor sorting, indicating that the sub-delta was in a process of development. The erosion accumulation processes were superimposed. The evolution models of the YRD since 1855 were successfully clarified, providing theoretical references for deposition processes in the YRD.

下游老河道频繁的摆动和改道与黄河亚三角洲叶瓣的多相重叠并存。此外，亚三角洲裂片在不同发育阶段的沉积体已知相互重叠。检查了 24 个短柱（长度小于 1 m）站的实验分析。此外，受黄河下游老河道回旋影响，不同历史时期的亚三角洲裂片处于不同的演化阶段，包括侵蚀退化（刁口）、冲淤平衡（清水沟、和神仙沟亚三角洲）和沉积作用（现在的河口亚三角洲）。沉积体的特征，伴随着海床的冲刷和淤积，发现对亚三角洲裂片的沉积特征有影响。完成聚类分析后，黄河三角洲(YRD)沉积体分为三种类型。I 型以目前的河口亚三角洲为主。它们的晶粒度频率分布曲线的平均晶粒度为 4.43$\phi$, 且分选适中, 说明黄河的泥沙补给是主要的源, 而海洋有持续接受陆源补给和泥沙的趋势。Ⅱ型砂含量明显高于Ⅰ型，砂成分大于40%。此外，频率累积曲线要么是双峰的，要么是多峰的，排序很差。该地区是由原始沉积物的严重侵蚀和转化形成的。III类地区的长概率曲线主要是单峰的。平均粒径在 5.26 左右波动$\phi$，排序不佳，表明亚三角洲处于发展过程中。侵蚀积累过程相互叠加。成功阐明了1855年以来长三角地区的演化模型，为长三角地区的沉积过程提供了理论参考。
