摘　　要：地质学家和社会学家广泛关注"人类世"这一新概念,但是,对于"人类世"的时间跨度仍然存在很大争议。在结合前人研究结果的基础上,对人类世提出了新的划分方法:认为人类世是一个以人类活动为主导因素的地质时期,要探讨人类世的生态与环境演化过程,就需要寻找一种有时间序列、分辨率高、分布范围广并且与生物活动紧密相关的沉积层。选取粪土层作为过去生态环境信息记录的新载体,运用多学科交叉的方法探索南极生态、气候和环境变化的问题,是南极无冰区生态地质学的理论基础。南极无冰区生态地质学是人类世生态地质学的组成部分,是沉积学与地球化学、考古学、生态学多学科交叉的结果,它的理论和方法已被成功地运用到北极和中国的南海地区,它应该放在全球的沉积学大平台上,开拓新的领域。并详细讨论了人类世生态地质学的研究方法及应用实例,对于了解人类世以来气候、环境和生态的变化及其与人类活动的关系具有重要意义。The new concept of ＂Anthropocene＂attracts wide concern among geologists and sociologists; however,there are still a lot of controversies with regard to the time span of the Anthropocene.Based upon previous research results,we proposed a new partitioning method for Anthropocene.Anthropocene is a geological epoch dominated by anthropogenic activities.In order to study the ecological history and environmental evolution during the Anthropocene,we need high-resolution and widely-distributed sediments which have good temporal series and close relationship with biological activities.Using ornithogenic sediments as a new carrier of ecoenvironmental records and a multidisciplinary approach,we have successfully studied the main issues of ecology,climate and environment in the Antarctica.The ecogeology of ice-free areas of Antarctica is the multidisciplinary cross science between sedimentology,geochemistry,archaeology,and ecology,it is an important part of Anthropocene ecogeology,its theories and methods have been successfully applied in the Arctic and South China Sea,and it should be extended as the great platform of global sedimentology to open up a new area.In this paper,we discuss in detail the research methods and applications of Anthropocene ecogeology.These methods are important for understanding the changes of climate,environment and ecology and their relationship with human activities during the Anthropocene.
