摘要
The Holocene double barrier-lagoon system on the west coast of the Yellow Sea consists of a 1600 m long inner barrier,a 1550 m long outer barrier,a 0.994 km2 inner lagoon and a 0.335 km2 outer lagoon(back-barrier estuary).The inner barrier formed about 7000-2500 aBP,gradually extending from south to north.The tidal inlet changed its location from the north end to the south end of the inner barrier about 2500 aBP under the strong NE storm wave action.After the southern small bay was filled up,northward longshore current transported sediments onto the north of the 12.0 highland cape.These sediments and the sediments transported out of the south end tidal inlet together formed a spit at the north of the 12.0 highland cape,which has gradually extended northward and formed the outer barrier and an outer lagoon between the two barriers.
