四海龙湾沉积物多指标数据集（公元900年以来）

本研究通过重建四海龙湾沉积物900年以来的总有机碳、总有机碳和总氮的摩尔比（C/N）、稳定有机碳同位素（δ13Corg）和Ca/Ti，以及硅酸盐矿物主要元素Si、Al和K含量的历史序列，平均分辨率约为10年，以气候变化为背景，来探究该地区人类活动的历史。综合多种代用指标的变化，以气候变化为背景，重建四海龙湾周围地区人类活动的演变历史，可深化对人类世科学的认知，也期望能给未来应对因人类活动造成的环境变化提供一定的参考。

This study reconstructs the historical proxy sequences of total organic carbon (TOC), the molar ratio of total organic carbon to total nitrogen (C/N), stable organic carbon isotope (δ¹³Corg), Ca/Ti ratio, and the contents of major elements Si, Al and K in silicate minerals from sediments of Sihai Longwan Lake over the past 900 years, with an average resolution of approximately 10 years, to investigate the history of human activities in this region against the background of climate change. By synthesizing the variations of multiple proxies and reconstructing the evolutionary history of human activities in the surrounding area of Sihai Longwan Lake under the context of climate change, this research aims to deepen the understanding of Anthropocene science, and is expected to provide valuable references for future responses to environmental changes caused by human activities.
