摘要:

西藏自治区“两江四河”(雅鲁藏布江、怒江、拉萨河、年楚河、雅砻河和狮泉河)流域是青藏高原高寒河谷人居环境、生态修复与荒漠化防治的核心区域,人工造林工程对构建高原生态安全屏障具有重要意义。作者通过Temporal-Spectral-Spatio Vision Transformer (TS2-ViT) 模型融合Sentinel-1/2遥感影像,结合林龄及人工林样本数据,研制得到基于TS2-ViT模型的西藏“两江四河”人工造林空间分布数据集(2021)。数据集内容包括:(1)西藏“两江四河”流域全域造林空间分布数据(30 m分辨率);(2)年楚河、拉萨河及雅江重点研究区造林数据(10 m分辨率)。数据集存储为.tif格式,一共由26个数据文件组成,数据量为23.8 MB(压缩为1个文件,892 KB)。
