渤海湾全新世贝壳堤:时空分布和海面变化标志点OA北大核心CSCDCSTPCD
Holocene cheniers: spatial and temporal distribution and sea level indicators in Bohai Bay
以他人和本研究小组对渤海湾西岸贝壳堤平原的全新世贝壳堤研究为基础,重新考订了贝壳堤的底板形态,发现底板多向海倾斜,经多处水准测量获得的前、后缘底板平均高差为1m.堤底板的前、后缘位于形成时的平均大潮潮差的垂直范围内.底板的高差,或依实测值、或依高差平均值补足至1m,由此确定底板的高度误差范围.当对应当时的平均大潮差时,再进一步补足至±1.5m的垂直范围,堤底板遂成为海面变化标志点.经过对96个14C数据的考订,补正了贝壳堤的时空分布,重新肯定了Ⅱ…查看全部>>
Based on studies of the Holocene cheniers on the Chiner Plain along the west coast of Bohai Bay, this paper has reexam-ined the bottom morphology of cheniers and found that the bottom usually inclines seaward with average vertical difference of lm between front-foot and rear-base, as evidenced by leveling measurements at various sites. Both fore-base and rear-base were developed within the vertical range of the contemporaneous mean high tides. Thus, the indi…查看全部>>
