全新世云台山的海陆变迁

CHANGE OF THE SEA OR LAND OF YUNTAI MOUNTAIN IN THE HOLOCENE

云台山,全新世之前位在陆上,早全新世逐渐为海水侵漫,在距今6000年前后的中全新世高海面时期,沦为海上孤岛。此后历经几度沧桑之变,直至清代中、后期,由于海面下降,海岸东退以及黄河泥沙淤积等诸多因素的作用,才最终与大陆相连,成为雄踞海州湾南侧的濒海山丘。

The Yuntai mountain, which was on land before Holocene, was overflowed gratually by the seawater during Early Holocene, and turned to an isolated island in the high sea lever of Middle Holocene. Later it underwent several great changes--the alteration of sea or land, till the middle and late Qing Dynasty, the Yuntai mountain was virtually become an abrupt mountain bordering on the south side of the Haizhou gulf due to the influence of such factors as the drop in sea level, coastline's drawing back to the east, the deposition of sand and silt of the Yellow River and so on.
