【摘要】：地質(zhì)學家和社會學家廣泛關(guān)注"人類世"這一新概念,但是,對于"人類世"的時間跨度仍然存在很大爭議。在結(jié)合前人研究結(jié)果的基礎上,對人類世提出了新的劃分方法:認為人類世是一個以人類活動為主導因素的地質(zhì)時期,要探討人類世的生態(tài)與環(huán)境演化過程,就需要尋找一種有時間序列、分辨率高、分布范圍廣并且與生物活動緊密相關(guān)的沉積層。選取糞土層作為過去生態(tài)環(huán)境信息記錄的新載體,運用多學科交叉的方法探索南極生態(tài)、氣候和環(huán)境變化的問題,是南極無冰區(qū)生態(tài)地質(zhì)學的理論基礎。南極無冰區(qū)生態(tài)地質(zhì)學是人類世生態(tài)地質(zhì)學的組成部分,是沉積學與地球化學、考古學、生態(tài)學多學科交叉的結(jié)果,它的理論和方法已被成功地運用到北極和中國的南海地區(qū),它應該放在全球的沉積學大平臺上,開拓新的領(lǐng)域。并詳細討論了人類世生態(tài)地質(zhì)學的研究方法及應用實例,對于了解人類世以來氣候、環(huán)境和生態(tài)的變化及其與人類活動的關(guān)系具有重要意義。
[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.
