Abstract:
A number of geomorphological, sedimentological and biological evidences related witk the Holocene sea-land shift are described, 26 14C datings of shell, peat or mud and wood samples are included, and the history of the Holocene sea-land shift discussed. In the early period of the Early Holocene marine transgression reached not the northern Jiangsu. In the early period of the Middle Holocene the transgression reached its maximum range to the Lixiahe drainage, and in the later period of the Middle Holocene the coastline shifted interruptedly seaward and stayed at the Donggon chenier for a long time. In the Late Holocene, especially between 1194 and 1855 when Huanghe (Yellow) River emptied into the Huanghai (Yellow) Sea at northern Jiangsu, the coastline shifted rapidly seaward.
