| 摘 要： | 根据多次海洋调查的多波束、表层沉积物资料及中法合作海洋地质调查的浅地层剖面资料,对东海陆架西北部的地貌进行详细分类,探讨该区环境演化规律。分析结果表明,该区存在潮流沙脊,潮流冲刷槽、暗礁等多种地貌形态;该区发育多期潮流沙脊,反映了本区晚更新世以来经历了多次海进和海退过程。

| Abstract: | In this paper,the multi-beam sonar data,surficial sediment data and subbottom profiling data collected from Sino-France joint marine geology surveys are used to make a detailed classification of geomorphology on the northwestern East China Sea shelf,and the environmental evolution regularity in the sea area is also discussed.It is shown from the analysis results that there are various geomorphologies,including tidal sand ridge,tidal scour channel,submerged reef and so on,and several periods of tidal sand ridges are developed in the sea area,which reflects that this area has undergone several marine transgression and regression processes. |
