当今人类正在面临大气二氧化碳浓度升高、全球变暖、海洋酸化等一系列气候环境问题,有科学家提出这可能导致第6次生物大灭绝.类似的灾难事件在地质历史上多次发生,因此以史为鉴、以古示今才能更好地认识、应对和解决这些问题.显生宙最大的一次生物灭绝事件发生在2.52亿年前的二叠纪-三叠纪之交,超过90%的海洋物种永久消失.此次生物灭绝的过程和原因一直是科学家关注和致力解决的关键科学问题之一.近年来的研究表明当前人类面临的这些极端的气候环境事件在2.52亿年前也都有发生,而且更为严重.本文重点围绕近年来有关二叠纪-三叠纪之交的生物和环境事件研究进展,结合化石和环境指标的地质记录以及生物与环境之间的相互作用关系,总结生物灭绝的过程和形式及相关环境因子的贡献,并探讨残存生物能够躲过这次灾难事件得以延续和发展的内在机制和外界原因.
Nowadays, human beings are facing a series of climate and environmental problems such as the increase of atmospheric carbon dioxide concentration, global warming and ocean acidification. Some scientists have suggested that this may result in the 6th massacre. Similar catastrophe events occurred many times in geological history. Therefore, taking history as reference , To ancient Antiquity in order to better understand, deal with and solve these problems.The largest Episimate biological extinction event occurred in 252 million years ago Permian - Triassic fold, more than 90% of the permanent marine species Disappear.The biological extinction process and reason has been one of the key scientific problems that scientists are concerned about and devoted to solving.Recent studies have shown that these extreme climate and environmental events facing mankind have also occurred 252 million years ago, More serious.This paper focuses on recent years on the Permian - Triassic biological and environmental events research progress, combined with fossil and environmental indicators of geological records and biological and environmental interactions between the summary of the biological extinction Process and form and related environmental factors, and explore the survival of survivors can survive this disaster and development In the mechanism and external causes.
