【摘要】：正海底峡谷是海底长条形且窄而深的负地形,在主动和被动大陆边缘以及岛弧附近都有出现,横剖面上呈现出"U"字型和"V"字型两种形态。我国东海、南海均发现众多的海底峡谷,如东海陆坡上发育十几条形态各异、规模不等的海底峡谷,在南海已发现的海底峡谷主要有:珠江外海底峡谷、东沙峡谷、南海西南部海底峡谷、台湾海峡南部的高屏海底峡谷、高雄峡谷、台湾浅滩海底峡谷和澎湖峡谷等。作为"陆-海"连接的重要组成单元,深水峡
[Abstract]:The positive submarine canyons are long, narrow and deep negative topography, which appear in the active and passive continental margin and near the island arc, and there are two types of "U" and "V" on the cross section of China's East China Sea. Many submarine canyons have been found in the South China Sea, such as more than a dozen subsea canyons of different shapes and different scales on the east coast slope. The main submarine canyons have been found in the South China Sea: the submarine canyons outside the Pearl River and the Dongsha canyons. The sea canyon in the southwest of the South China Sea, the Gaoping submarine canyon in the south of the Taiwan Strait, the Kaohsiung canyon, the shoal submarine canyon in Taiwan and the Penghu canyon. As an important component unit of the "land-sea" connection, Deepwater Gorge.
