摘　　要：早三叠世作为显生宙最大生物灭绝之后的一段特殊地质历史时期,不仅见证了海洋生物的迟缓复苏,而且记录了极其动荡的海洋环境变化,该时期异常的生物环境事件及其机制已经成为当前国际地质学者关注的重大科学问题之一.近些年来,研究学者在早三叠世的碳-氮-硫异常循环研究中取得了许多重要的进展,这对深入理解该时期的环境演变及其对生物复苏的影响十分重要.重点回顾近年来关于早三叠世古海洋碳-氮-硫循环方面的研究进展,对当前存在的科学问题及发展趋势进行分析和总结.Early Triassic oceans recorded the delayed biotic recovery and the large perturbed environments. Hence, the environmental events and their mechanism became one of the key scientific topics for the geological scientists. In recent years, researchers have made many significant progresses in the marine carbon-nitrogen-sulfur cycles of the Early Triassic, which are important for understanding the co-evolution between the biotic recovery and environmental changes. The progress, problem and future development in the researches of carbon-nitrogen sulfur cycles during the Early Triassic have been reviewed and summarized.
