台湾沿岸全新世海平面波动

HOLOCENE SEA LEVEL CHANGES ALONG THE COAST OF TAIWAN

本文汇集了一批台湾沿岸全新世隆起海相沉积物样品的１４Ｃ年代、高程数据，尝试以华南海平面变化曲线为参照系，从相对海平面变化中剔除构造运动的影响，恢复台湾古海平面的高度，进而探讨海平面的波动变化，并与闽、粤沿岸海平面变化进行比较。

ccording to the data of altitude and 14C dating for 99 samples from the marine deposit at the coast of Taiwan, a curve of Holocene sea level changes along Taiwan coast is drawn in this paper, while that along the coasts of South China being taken as reference. The results indicate that: 1) The sea level had been fAst upriSing before 5000 a B. P.. The highest stand of sea level occurred about 5190 a B, P., with an altitude of about+ 3. 2m. 2) The sea level has been fluctuating around its present position since 5000 a B. P.. Four hash sea levels occurred 41201 120 a B. P, 3250±40 a B. P., 1970t 40a B. P., and 13001 120 a B. P., resspectively, and the altitude of sea level has been decreasing gradually. 3) From the comparison of sea level changes between the coasts of Taiwan, Fujian and eastern of Guangdong, eight cycles of sealevel changes or transgression during Holocene along the coasts of the Taiwan Strait can be determined.
