摘要:

作者整合全球建设用地和城市中心位置数据,重建了全球1992-2020年城市扩展过程;利用土地利用情景变化动力学-城市模型,模拟了五种社会经济路径下全球2020-2050年城市扩展过程,得到全球1992-2050城市扩展模拟数据集。基于历史数据的精度评价表明,该模型模拟结果的Kappa系数为0.88。本数据集内容包括:(1)1992-2020年逐年全球历史城市建成区范围;(2)2025-2050年每五年全球未来城市建成区预测范围。数据集的空间分辨率为1 km,存储格式为.tif,一共由383个数据文件组成,数据量为498 MB(压缩为1个文件,23.7 MB)。该数据集的数据论文拟发表在《全球变化数据学报(中英文)》2024年第8卷。
