东海大陆架南缘海域地层声学剖面及地质解释

阐述了对东海陆架南缘勘查区进行的高分辨率的浅地层探测情况。通过对测区的浅地层声学剖面的解释和研究，笔者认为:声学剖面较直观地反映了该区的海底地形、地貌、浅地层沉积物结构、构造及海底基岩埋深状况，对恢复该区沉积地质环境和发育历史有重要意义。

Subbottom Profiling and Its Geological Interpretation on the Southern Margin of Continental Shelf of the East China Sea

It is expounded the probing of the high resolution subbottom profile on the southern margin of the continental Shelf of the East China Sea.According to the data of subbottom profile the detail geological interpretations are as follows:①the high resolution subbottom profiles record the submarine topography,geomorphy and sedimentary structures of the study area directly,which can be used for studing the sedimentary environment and geolgical history;②three paleao-river valleys have been probed and it is shown that the shoreline of china Sea shelf in the umu galacial(Late Pleistocene Epoch) maybe was 150 m below the present sea levef;③ in this area,the complicated geomorophy and structures is related to the earthguake、volcanicity,and soon.
