全球1km分辨率人为活动压力指数变化数据集（2010-2020）

本数据集基于地表覆盖及网格地表覆盖变化数据集产品，聚焦全球SDG 15.1、15.2、15.4指标的五年评估。 人为活动压力采用夜间灯光指数和土地开发强度构建无量纲综合指标，来反映区域人为活动对生态系统的干扰程度。分析了2010——2020年全球陆地、山地和自然保护地各生态系统人为压力指数变化，评估了人为活动对全球陆地、山地和自然保护地生态系统格局的影响。This dataset is based on land cover and gridded land cover change dataset products, focusing on the five-year assessment of the global SDGs 15.1, 15.2 and 15.4 indicators. To quantify anthropogenic pressure, a dimensionless comprehensive indicator was constructed using nighttime light index and land development intensity, which reflects the degree of disturbance of regional anthropogenic activities to ecosystems. This dataset analyzed the changes in anthropogenic pressure indices of various ecosystems across global terrestrial, mountainous and protected areas from 2010 to 2020, and evaluated the impacts of anthropogenic activities on the ecosystem patterns of global terrestrial, mountainous and protected areas.
