摘要/Abstract

摘要： 由于气候变化与人类活动的影响，中国生物多样性受到严重威胁，急需开展保护工作。《昆明-蒙特利尔全球生物多样性框架》提出“3030目标”，即到2030年保护全球至少30%的陆地和海洋。目前中国各级各类自然保护地虽覆盖陆域国土面积达18%，但距30%的目标仍有差距，亟需识别更多优先保护地。研究人员基于丰富度、特有性、受威胁程度、进化历史等多样性指标均识别出中国西南地区是被子植物的多样性热点，进一步利用新-古特有分析、整合多个指标的综合丰富度指数和综合系统发生多样性指数识别出更多独特的保护空缺，为完善中国自然保护地体系建设提供了科学支撑。

Abstract: Due to the impact of climate change and human activities, China’s biodiversity is under serious threat, which requires urgent conservation actions. According to the Kunming-Montreal Global Biodiversity Framework, the “3030 Target” calls for at least 30% of the world’s land and oceans to be protected by 2030. Although the current protected areas in China have covered ca. 18% of its land area, large conservation gaps remain to achieve the 30% target. It is therefore urgent to identify more conservation priorities. Researchers identified southwest China as the diversity hotspot of flowering plants based on numerous diversity indices, such as those incorporating richness, endemism, vulnerability, and evolutionary history. Furthermore, unique conservation gaps is identified using the categorical analysis of neo- and paleo-endemism (CANAPE), integrative richness-based index (I_rich), and integrative phylogenybased index (I_phyl). These progresses provide solid scientific support for improving China’s nature reserve system.
