华夏故土过去两千年(秦至清代)人口分布的网格化数据
收藏资源简介:
本研究利用现代人口和环境因子数据, 通过地理探测器分析辨识了人口分布的显著影响因子, 进而构建了基于随机森林回归算法的人口空间分布模型, 最后以史学界考订的历史人口数据为基础, 重建了1776~1953年6个时间断面中国传统农区10×10km分辨率的人口空间分布, 并分析了人口分布的时空变化特征.
This study employed modern demographic and environmental factor datasets to identify the significant influencing factors of population distribution via Geographical Detector analysis, then constructed a spatial population distribution model based on the Random Forest Regression algorithm. Finally, based on the historically calibrated population data verified by the historical academic community, the study reconstructed the spatial distribution of population in traditional agricultural regions of China at a 10×10 km resolution across six temporal snapshots spanning from 1776 to 1953, and analyzed the spatio-temporal variation characteristics of population distribution.
