Detailed temporal mapping of global human modification from 1990 to 2017

Data on the extent, patterns, and trends of human land use are critically important to support global and national priorities for conservation and sustainable development. To inform these issues, we created a series of detailed global datasets for 1990, 2000, 2010, 2015, and 2017 to evaluate temporal and spatial trends of land use modification of terrestrial lands (excluding Antarctica). Our novel datasets are detailed (0.09 km2 resolution), temporally consistent (for 1990-2015), comprehensive (11 change stressors, 14 current), robust (using an established framework and incorporating classification errors and parameter uncertainty), and strongly validated. We also provide a dataset for ~2017 with 14 stressors for an even more comprehensive dataset. Also provided is a land/water mask to support subsequent analyses.

人类土地利用的范围、格局与趋势相关数据，对于支撑全球及各国的生态保护与可持续发展优先事项至关重要。为支撑此类研究议题，我们构建了一套覆盖1990、2000、2010、2015及2017年的精细化全球数据集，用于评估陆地（不含南极洲）土地利用改造的时空演变趋势。本研究构建的新型数据集具备以下优势：空间精细化（分辨率达0.09平方千米）、时间一致性（针对1990-2015年时段）、覆盖全面（包含11种土地利用变化胁迫因子与14类当前土地利用类型）、结果稳健（采用成熟框架构建，并纳入分类误差与参数不确定性），且经过严格验证。我们还构建了一套覆盖约2017年的数据集，包含14种胁迫因子，以进一步提升数据集的全面性。此外还提供了水陆掩膜数据集，用于支撑后续分析工作。
