本文列举一批台湾珊瑚礁等全新世海相沉积物的１４Ｃ年龄数据，并从地形面、不整合面、化石地层等方面论述台湾珊瑚礁的时代、发育演变规律，及其与板块构造运动、海平面变化环境变迁的关系。认为至今５０００年以来，台湾有过５次高海平面，波动周期约１０００年，幅度３～４ｍ或６～７ｍ，全新世以来台湾岛属热带区。 In this paper, a batch of 14C age data of Holocene marine sediments such as coral reefs in Taiwan are listed. The age, development and evolution of coral reefs in Taiwan are discussed from the aspects of terrain, unconformities and fossil strata. Change the relationship between changes in the environment. Since 5,000 years ago, Taiwan has had five high-level sea levels with a fluctuation period of about 1,000 years, an amplitude of 3 to 4 meters or 6 to 7 meters. Since the Holocene, Taiwan has been a tropical island.
