| 摘 要： | On the basis of the multi.channel seismic data and the other data, using 2DMove software, the tectonic evolution in three seismic profiles was restored since Pliocene. The tectonic restoration results show that： （1） the initial active center lay in the west slope and then was transferred to east and south via trough center during the evolution process; （2） several main normal faults controlled the evolution of the southern Okinawa Trough; （3） since Late Pliocene, the southern Okinawa Trough has experienced two spreading stages. The early is depression in Early-Middle Pleistocene and the late is back-arc spreading in Late Pleistocene and Holocene, which is in primary oceanic crust spreading stage.
