The transformation of the Earth’s land surface by mineral extraction and construction is on a scale greater than natural erosive terrestrial geological processes. Mineral extraction statistics can be used as a proxy to measure the size of the total anthropogenic global sediment flux related to mineral extraction and construction. It is demonstrated that the annual direct anthropogenic contribution to the global production of sediment in 2015 was conservatively some 316 Gt (150 km3), a figure more than 24 times greater than the sediment supplied annually by the world’s major rivers to the oceans. The major long-term acceleration in anthropogenic sediment flux started just after the Second World War and anthropogenic sediment flux overtook natural fluvial sediment flux in the mid-1950s. Humans are now the major global geomorphological driving force and an important component of Earth System processes in landscape evolution. The changing magnitude of anthropogenic sediments and landforms over time are significant factors in the characterisation of the proposed new epoch of geological time – the Anthropocene.

人类是21世纪最重要的全球地貌驱动力

通过矿物提取和建造来改变地球陆地表面的规模要大于自然侵蚀性地球地质过程。矿物提取统计数据可以用作度量与矿物提取和建筑有关的人为总全球沉积物通量的总和。事实证明,保守估计,2015年每年对全球沉积物的直接人为贡献约为316 Gt(150 km3),这一数字是世界主要河流每年向海洋提供的沉积物的24倍以上。第二次世界大战后,人为沉积物通量开始了长期的主要增长,在1950年代中期,人为沉积物通量超过了自然河流沉积物通量。现在,人类是主要的全球地貌驱动力,也是景观演化中地球系统过程的重要组成部分。人为沉积物和地貌随时间变化的幅度是表征拟议的新地质时代-人类世的重要因素。
