| 摘 要： | 沉积物表层样口和岩芯样口综合分析及浅层地震剖面判读解表明，晚更新世以来冲绳海槽持续发生和普遍存在浊流活动。通过对浊积层体积规模，发生频率，分布范围以及浊流形成条件的分析，探讨了浊流作用的灾害特点，后者可作为该区环境地质评价及海底工程设计的参考和依据。

| Abstract: | A synthetical study on sediment samples from the surface deposition and cores as well as an interpretation of the shallow seismic sections indicate s that there has been a turbid flow always occurred and widely appeared in Okinawa Trough since the Late Pleistocene. The hazardous characteristics of the trubid flow is discussed based on an analysis of turbidity thickness, occurrence frequency and turbidity distribution, which would be as reference for geological environment evaluation and submarine engineering developing plan in this maritime space. |
