中文摘要：

地质历史时期大规模火山活动与同期古环境、生物多样性显著变化之间的时空耦合关系、内在机制联系,日渐成为地球科学领域广受关注的热点问题之一。本文聚焦二叠纪,系统回顾了近年来关于二叠纪3个大火成岩省（塔里木、峨眉山、西伯利亚）及其同期古环境背景、生物演化事件方面的研究进展,并对二叠纪大火成岩省研究领域的争议性问题进行了总结和展望。

英文摘要：

The spatial and temporal relationship, and the fundamentally mechanistic association between massive volcanism and contemporaneous changes in paleoenvironment and biodiversity,most notably the connection between large igneous provinces and mass extinctions,remain an increasingly hot topic in Earth Sciences,which attract the attention from not only the scientific community but also the general public. This paper focuses on the Permian geological events and briefly reviews recent progresses in the studies of three Permian Large Igneous Provinces（ Tarim,Emeishan,and Siberian）and their potential impact on paleoenvironment and biodiversity. Some controversial problems in this field are highlighted,and perspectives for future study are also discussed.
