1900-2019年中国土地利用和覆盖变化数据集
收藏资源简介:
在广泛查阅历史资料数据的基础上,开发了一种自上而下的模型算法,重建生成了1900-2019年中国农田、森林和湿地等的历史分布数据集,融合了来自报告、实地调查和卫星图像的土地利用变化信息,并利用省级统计数据和遥感产品对重建的LUCC数据库进行了验证。该数据集更正了基于FAO数据所衍生的LUCC数据集在中国区域的偏差,为我国陆地生态系统碳收支状况准确评估提供了重要支撑。
Based on extensive review of historical datasets, a top-down model algorithm was developed to reconstruct and generate a historical land distribution dataset covering croplands, forests, wetlands and other land types in China from 1900 to 2019. This dataset integrates land use change information from reports, field surveys and satellite imagery, with the reconstructed LUCC database validated using provincial statistical data and remote sensing products. It corrects the biases of LUCC datasets derived from FAO data in the Chinese region, providing critical support for the accurate assessment of terrestrial ecosystem carbon budgets in China.
