人们为了探讨第四纪期间所发生过的地质事件,早在100多年前就开始了冰期与间冰期、世界气候变化和随之而来的海面变动的研究,并试图了解它们过去的演变规律,推论未来的变化。近卅年来,随着C测试技术的发展和大量实际资料的积累已经有可能对于近十万年以来的冰期、间冰期的划分,世界气候的周期性变化与世界洋面的升降变动提供越来越精确的资料,从而 In order to investigate the geological events that took place during the Quaternary period, people started to study glacial and interglacials, world climate change and the consequent sea-level changes as early as 100 years ago and tried to understand their past evolution patterns. Infer the future changes. In recent years, with the development of C test technology and the accumulation of a large amount of actual data, it has been possible to provide more and more information on the glacial and interglacial divisions of nearly 100,000 years, the cyclical changes in the world climate and the fluctuations of the world’s oceans The more accurate information, thus
