以渤海湾西岸大港区穿港路采土场内贝壳堆积层中的闭合贝壳、单瓣贝壳和贝壳碎屑为对象，开展全新世再搬运贝壳的驻留时间效应研究。通过对5个剖面（剖面2、4~7）、3个层位的15个贝壳测年样品（闭壳合、单瓣壳和贝壳碎屑）AMS 14C年龄对比，初步获得研究区单瓣贝壳（或腹足类）的驻留时间经验值为440a、贝壳碎屑的驻留时间经验值为650a。

The shelly layers in Chuanganglu pit of Dagang District on the west coast of Bohai Bay were taken as the study object for investigating the residence time of the Holocene reworked shells. Based on an analysis of the AMS 14C dating results of 15 samples, in-cluding articulated, disarticulated valves and shell hash, which were taken from the three shelly layers of five sections (Section 2 and sections 4~7), the authors obtained the residence time of 440a for the disarticulated shells and 650a for the shell fragments, on the basis of a comparison with the ages of the articulated shells taken from the same layers.
