鲁北平原典型剖面4000年古火重建数据集

Dataset for the Reconstruction of Paleofire over 4000 Years in a Typical Profile of the Lubei Plain Region

以山东省广饶县常徐村的典型陆相沉积物剖面采集的样品为研究对象,通过对样品的室内分析获得黑碳、磁化率、烧失量和地球化学元素等多种环境代用指标数据,借助GetData软件和相关文献资料获得与气候指标和人类定居点相关的数据,并将其与年代数据结合,形成一个综合数据集。该数据集的分析主要通过不同指标的描述性统计及箱状图揭示所涉及数据的范围和离散性。运用主成分分析中的载荷值以及相关性分析来表明不同主成分代表的意义,再利用火灾因子得分在不同年代的变化趋势,对不同时期火灾发生的主控因子进行分析。数据集存储格式为.shp和.xlsx格式,由8个数据文件组成,数据量为74.3 KB(压缩为1个文件,69 KB)。

This research studies samples collected from a typical terrestrial sediment profile in Changxu Village,Guangrao County,Shandong Province.The research involves indoor analysis on those samples to obtain various environmental proxy data,including Black carbon,Magnetic susceptibility,Loss on ignition,and geochemical elements.Data about climate indices and settlements were collected through Get Data software and relevant literature,and combined with chronological data to form a comprehensive dataset.Such dataset analysis primarily involves descriptive statistics and box plots revealing the range and dispersion of data included.Principal component analysis and correlation analysis are employed to interpret meanings represented by different principal components.Furthermore,fire factor scores momentum over different periods are to analyze main controlling factors of fires in various eras.The dataset is stored in.shp and.xlsx formats,consisting of 8 data files,with a total size of 74.3 KB(compressed into one file of 69 KB).
