| 摘 要： | 高分辨力的声学仪器调查表明,现行黄河口水下三角洲海底的形貌十分复杂,由于高浓度巨量黄河泥沙快速沉积的结果,使河口底坡出现了大量的不稳定性现象,如塌陷冲沟,高密度沉积物重力流,切割—充填结构海底,V形水下河谷、滑塌等。根据海底扰动程度作了分区,划分了地形单元,并对不同的海底形态的成因作了分析。比较了1985和1986年两个航次考查结果的变动,分析了原因。

| Abstract: | High resolution acoustic surveys over the modern Huanghe Delta showed that the bottom morphology of the delta was quite complicated. Intensive subaqueous slope instability was found on the delta area. The collapses gullies, slumps, cut and fill structures, eroded subaqueous channels, sediment gravity flows were observed. The slope instability was mostly resulted from rapid deposition of huge amount of sediment from the Huanghe River with very high concentration and the waves in the estuarine area. Different morphological elements and areas of disturbance were classified. The origins of the morphology were analyzed. |
