Abstract

Human activities have had significant impacts on the natural environment and the concept of Anthropocene sparked many debates during the Holocene. Extensive research has been conducted in investigating past human activities by using multi-proxies in geological archives. However, previous research has normally focused on analyzing the human activity with limited proxy records and lacks integrated studies utilizing multiple types of proxies within the same region. Through multi-proxy analysis of pollen and heavy metal records from 24 sites across Southern, Northern, and Southwestern China, this study reveals the spatiotemporal variations in human activities and different responses of proxies to human activities. The results indicate that: (i) the integrated Z-Score results of pollen and Pb suggest the spatial differences in the history of human activities, with Southern China experiencing the earliest anthropogenic influence, followed by Northern and Southwestern China. (ii) different proxies exhibit varying responses to human activities, with pollen records typically responding earlier than heavy metal records, due to the different inherent characteristics of proxies and historical stages of human activities. (iii) there are also temporal differences in altitude for human activities indicated by different proxies. Human activities of the same type mainly occur in low-altitude areas and then spread to high-altitude areas. Therefore, it is essential to utilize multi-proxy in various geological archives to reconstruct a more comprehensive history of human activities and provides deeper insights into human-environment interactions.
中国主要季风期花粉和Pb记录揭示的全新世人类活动复杂时空异质性
人类活动对自然环境产生了重大影响,人类世的概念在全新世期间引发了许多争论。利用地质档案中的多代理资料对过去人类活动进行了广泛的研究。然而,以往的研究大多集中在有限的代理记录下对人类活动的分析,缺乏在同一区域内利用多种类型代理的综合研究。通过对中国南方、北方和西南地区24个站点花粉和重金属记录的多代理分析,揭示了人类活动的时空变化及其对人类活动的不同响应。结果表明:(1)花粉和Pb的综合Z-Score结果反映了人类活动历史上的空间差异,华南地区受人类活动影响最早,其次是华北和西南地区。(ii)由于代用物的内在特征和人类活动的历史阶段不同,不同代用物对人类活动的响应不同,花粉记录的响应通常早于重金属记录。(iii)不同代用物所显示的人类活动的海拔高度也存在时间差异。同类型的人类活动主要发生在低海拔地区,然后向高海拔地区扩散。因此,利用各种地质档案中的多代理来重建更全面的人类活动历史,并为人类与环境的相互作用提供更深入的认识是必要的。

期刊介绍: Anthropocene is an interdisciplinary journal that publishes peer-reviewed works addressing the nature, scale, and extent of interactions that people have with Earth processes and systems. The scope of the journal includes the significance of human activities in altering Earth’s landscapes, oceans, the atmosphere, cryosphere, and ecosystems over a range of time and space scales - from global phenomena over geologic eras to single isolated events - including the linkages, couplings, and feedbacks among physical, chemical, and biological components of Earth systems. The journal also addresses how such alterations can have profound effects on, and implications for, human society. As the scale and pace of human interactions with Earth systems have intensified in recent decades, understanding human-induced alterations in the past and present is critical to our ability to anticipate, mitigate, and adapt to changes in the future. The journal aims to provide a venue to focus research findings, discussions, and debates toward advancing predictive understanding of human interactions with Earth systems - one of the grand challenges of our time.
