| 摘 要： | 通过对现代长江口外东海内陆架和外陆架三条地震剖面的地层和埋藏地貌分析 ,并经与相关钻孔和现代长江三角洲第四纪研究资料对比 ,在东海陆架研究区内未发现末次盛冰期时古长江沉积和古河谷 ,前人所称之长江古河谷实际上是现代潮流水道 .认为当时长江很可能未曾由研究区流经东海陆架入冲绳海槽

| Abstract: | Based on the stratigraphic and buried geomorphic analysis of three seismic profiles located in the inner and outer shelves of the East China Sea out of the present Changjiang River's mouth, and contrasting with some relevant geologic cores and Quaternary researches on the modern Changjiang River Delta, it is found that there are no paleosediments and paleochannels of the Changjiang River formed in the last ice age maximum in the study area. The paleochannels of the Changjiang River as which former researchers were considered are actually present tidal channels. Therefore, probably the Changjiang River did not flow by the East China Sea shelf and enter the Okinawa Trough during that period. |
