摘要
风暴或台风或飓风天气下,强烈波浪作用掀起海底沉积物进入运动状态,引发海底沉积物流,使沉积物向海底峡谷流动,进而进入深海沉积。在陆架近岸区,对于风暴作用下沉积物流的起源过程,还缺少系统描述。本文将台风或飓风条件统称到风暴条件,由此条件作用所引发的沉积物流称为风暴沉积物流,考虑风暴沉积物流的沉积物来源机制为海岸侵蚀、海底液化、河流输入,探讨给出风暴引发的海底沉积物流起源过程模式,同时也指出考虑起源过程的海底沉积物流类型的可能变化。本文所给出的风暴沉积物流起源过程模式,可为浊流及其沉积的研究提供沉积物源区过程的参考。
Under storm or typhoon or hurricane weather,strong waves can set off seafloor sediment into motion,causing the seafloor sediment flows generated submarine canyon flow,and then deposited into the deep sea.However,the origin of storm sediment flows in coastal areas has not been clearly stated.In this paper,typhoon or hurricane conditions are collectively referred to as storm conditions,and the sediment flows caused by these conditions is called storm sediment flows.Considering the sediment source mechanism of storm sediment flows is coastal erosion,submarine liquefaction and river input,the origin of submarine storm sediment flows is discussed.Also,possible variations in the type of sediment flows considering the origin process are pointed out.
