河西走廊古遗址时空演变与环境变迁
收藏资源简介：
本数据集的遗址数据来源于甘肃省文物考古研究所和北京大学考古文博学院 2011 年编著出版的《河西走廊史前考古调查报告》。地图数据来源于国家科技基础条件平台 —— 国家地球系统科学数据共享服务平台（ http://www.geodata.cn/），包括：中国 90 m 分辨率 DEM；中国 1 ∶ 250000 一级、三级、四级和五级河流分级数据集；中国 1 ∶ 4000000 植被数据集；中国 1 ∶ 100000 现状沙漠数据集。通过整理河西走廊考古调查资料，应用文化分布界值文化重心等方法综合分析该区古文化的时空演变过程，并应用 GIS技术提取相应遗址点现今的环境（高程、河流、植被和沙地）信息，结合古人类生产生活方式推测该区古今环境变化及其原因，并分析了该区域古文化演变的驱动机制。本数据集可直接为河西走廊地区遗址的古今演化提供一定的规律支撑。
The site data of this dataset is sourced from "Prehistoric Archaeological Survey Report of the Hexi Corridor", compiled and published in 2011 by the Gansu Provincial Institute of Cultural Relics and Archaeology and the School of Archaeology and Museology, Peking University. The map data is obtained from the National Science and Technology Infrastructure Platform – National Earth System Science Data Sharing Service Platform (http://www.geodata.cn/), including: 90 m resolution Digital Elevation Model (DEM) of China; 1:250,000 scale first, third, fourth, and fifth order river hierarchical datasets of China; 1:4,000,000 scale vegetation dataset of China; and 1:100,000 scale current desert dataset of China. By organizing archaeological survey materials of the Hexi Corridor, comprehensive analyses of the spatiotemporal evolution of ancient cultures in this region were carried out using methods such as cultural distribution boundary values and cultural centroid. Geographic Information System (GIS) technology was employed to extract current environmental information (including elevation, rivers, vegetation, and sandy land) for the corresponding archaeological sites. Combined with the production and lifestyle patterns of ancient humans, changes in the ancient and modern environment of the region and their underlying causes were inferred, and the driving mechanisms of ancient cultural evolution in this area were analyzed. This dataset can directly provide support for identifying regular patterns in the ancient and modern evolution of archaeological sites in the Hexi Corridor.
