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 re-sults,we proposed a new partitioning method for Anthropocene. Anthropocene is a geological epoch dominated by an-thropogenic 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 suc-cessfully applied in the Arctic and South China Sea,and it should be extended as the great platform of global sedim-entology to open up a new area. In this paper,we discuss in detail the research methods and applications of Anthropo-cene ecogeology. These methods are important for understanding the changes of climate,environment and ecology and their relationship with human activities during the Anthropocene.
