Impact of Climate Change on Protected Area Effectiveness in the Middle and Lower Yangtze River Basin: Implications for Adaptive Management

In the *Biodiversity Hotspots* folder, I have included species distribution data obtained from the IUCN, as well as environmental data used in MegaSDM to generate baseline conditions and species richness maps under the SSP2-4.5 and SSP5-8.5 scenarios for the 2050s, 2070s, and 2090s. In the *Conservation Gaps* folder, I have included baseline and future conservation gap maps (for the 2050s, 2070s, and 2090s under SSP2-4.5 and SSP5-8.5 scenarios), which were derived by identifying areas outside protected areas where species richness exceeds the 75th percentile for each time period but falls below the low human impact (LHI) threshold.在**生物多样性热点区域（Biodiversity Hotspots）**文件夹中，本数据集收录了源自国际自然保护联盟（International Union for Conservation of Nature，IUCN）的物种分布数据，以及供MegaSDM使用的环境数据；该环境数据用于生成2050年代、2070年代与2090年代在SSP2-4.5、SSP5-8.5情景下的基线条件与物种丰富度分布图。 在**保护空缺（Conservation Gaps）**文件夹中，本数据集收录了基线及未来保护空缺分布图（覆盖2050年代、2070年代与2090年代的SSP2-4.5、SSP5-8.5情景）；此类分布图通过识别保护区外的区域生成：这些区域在对应时间段内的物种丰富度超过75百分位，但低于低人类影响（Low Human Impact，LHI）阈值。
