| 摘 要： | 自１９８８年以来，通过多次野外考察和深入研究，在黄河口发现并确认存在大规模的水下滑坡体系。根据声纳图象和浅地层剖面记录，对滑坡进行分类命名和特征分析。研究表明，该滑坡体系中存在瓶颈状滑坡、平移板状滑坡和旋转滑坡３种类型；许多单个滑坡在下坡方向汇集成复合滑坡系统，有时数十条滑坡汇集成蜿蜒数公里的大规模复杂体系。滑坡冲沟分布广泛，将底坡表层切割得支离破碎，与密西西比河口比较，黄河口水下滑坡具有高含水、

| Abstract: | Large scale subaqueous landslide system was found and recognized in the subaqueousHuanghe River (Yellow River) Delta through seveLal field surveys since 1988. Bot-tleneck slides, translational plate slides and rotational slides were identified and de-scribed based on sidescan sonar images and subbottbm profile records. Many indivi-dual landslides merge with each other along their way down to the delta slope, for-ming complexes of landslides. Sometimes several tens of slides come down seaward to the end of the delta slope and gradually join together into a common, elongate,chute gully of several kilometers at the lower part of the delta front slope, forming a complicated landslide system. The landslides cut the slope surface into broken pie-ces with their chute gullies. Many depositional lobes formed by very diluted debric flows were found. The sediments coming out from the lower end of the gullies generate a delta front apron. In comparison with the subaqueous landslides in the Mississippi Delta, the Hu-anghe River case is characterized by high water content, shallow disturbance, multi-activization, minitype, variety in morphology, clear 3-dimensional geometry, distinct transport mechanism, wholly negative topography, etc.. The landslides play an im-portant role in the evolution of the Huanghe River Estuary and its Delta. |
