【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。
[Abstract]:Geologists and sociologists have paid close attention to the new concept of the "Anthropocene", but the time span of the "Anthropocene" is still controversial. Based on the results of previous studies, a new classification method for the Anthropocene is put forward: it is considered that the Anthropocene is a geological period dominated by human activities, and the ecological and environmental evolution process of the Anthropocene should be discussed. We need to find a time series, high resolution, wide distribution and closely related to biological activities. It is the theoretical basis of ecological geology in the ice-free region of Antarctica to select the dunghill as a new carrier for the record of ecological environment information and to explore the ecological, climatic and environmental changes in the Antarctic by means of a multidisciplinary method. Eco-geology in the ice-free region of Antarctica is an integral part of the Eco-geology of the Anthropocene. It is the result of the interdisciplinary study of sedimentology and geochemistry, archaeology and ecology. Its theory and method have been successfully applied to the Arctic and the South China Sea of China. It should be placed on the global platform of sedimentology and open up new fields. The research methods and application examples of the Eco-geology of the Anthropocene are discussed in detail. It is of great significance to understand the changes of climate, environment and ecology since the Anthropocene and their relationship with human activities.
