Abstract: 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.
