Global long-term ecoregion-level dataset of biodiversity indicators

This dataset provides spatially explicit biodiversity data for four terrestrial vertebrate groups—mammals, amphibians, reptiles, and birds. It includes five time slices (1990, 2020, 2030, 2050, and 2100), enabling the assessment of biodiversity patterns and their long-term changes from past to future. The dataset contains four ecoregion-level indicators: species richness, threatened species richness, species endemism, and AOH density. These indicators were derived from species-level environmental suitability mapping that integrates both climatic conditions and habitat constraints, thereby providing a consistent basis for representing species distributions across time. By combining broad taxonomic coverage, a long-term temporal framework, and standardized ecoregion-level metrics, this dataset supports analyses of global biodiversity patterns, conservation priorities, and projected future changes under environmental change.本数据集涵盖哺乳类、两栖类、爬行类与鸟类四大陆生脊椎动物类群，提供空间显性的生物多样性数据。数据集包含1990年、2020年、2030年、2050年及2100年共五个时间切片，可用于评估生物多样性格局及其从过去到未来的长期变化。本数据集包含四项生态区尺度指标：物种丰富度、受威胁物种丰富度、物种特有性以及AOH（栖息地面积，Area of Habitat）密度。上述指标均基于整合了气候条件与栖息地限制因子的物种级环境适宜性分布图推导而来，由此可为不同时段的物种分布表征提供统一基准。本数据集兼具宽泛的类群覆盖范围、长期时间框架与标准化的生态区尺度指标，可支撑全球生物多样性格局、保护优先级以及环境变化下未来预估变化的相关分析。
