摘要:

世界自然保护联盟(IUCN)红色名录是进行生物多样性保育的依据之一, 由红色名录评估结果数据计算的红色名录指数(RLI)是评估全球/国家/区域/某生物类群的物种整体生存状况的指标。红色名录指数计算的数据源可以是国家的红色名录评估结果数据, 也可以是IUCN全球红色名录评估结果数据; 中国已完成基于国家高等植物评估结果数据的红色名录指数计算, 而基于IUCN全球红色名录评估结果数据的红色名录指数尚未有报道。该研究基于IUCN评估方法框架, 考虑物种的分布区, 计算了基于IUCN全球红色名录评估结果数据的中国高等植物红色名录指数, 并与生物多样性指标联盟(BIP)仅采用苏铁类代表植物来计算国家红色名录指数的结果进行了比较。研究发现, 采用等步长法, 基于IUCN红色名录评估结果数据、合并IUCN和中国特有种评估结果数据、仅采用苏铁类评估结果数据3种数据源得到的中国高等植物红色名录指数分别为0.946 7、0.908 2和0.540 1, 仅采用苏铁类评估结果数据的方法低估了中国高等植物红色名录指数, 存在类群偏差, 所以用尽可能多的可靠数据进行该指数的计算更为合理。该研究在红色名录指数的计算方面进行了探索, 考虑了物种分布区。研究结果可以与其他国家的相关数据进行对比, 也可以为中国生物多样性相关的国际履约提供基础数据。

Abstract:

Aims The International Union for Conservation of Nature (IUCN) Red List provides a monitoring basis to biodiversity conservation. The Red List Index (RLI), derived from the Red List assessments, is an indicator of the status of species and taxonomic groups at global, national, and regional scales. This study aims to analyze the RLI of Chinese higher plants based on the IUCN global assessment data.
Methods The RLI can be calculated using either national or global assessment data. While the Chinese Red List Index based on national assessment data (nRLI) for higher plants has previously been reported, this study focuses on calculating Chinese higher plant Red List Index based on global assessment data (gRLI), following the IUCN assessment framework. By partitioning species’ Extent of Occurrence (EOO) within China and outside China, we derived the gRLI based on global assessment data. We then compared the resulting Chinese higher plant gRLI with the figures from the Biodiversity Indicators Partnership (BIP), which derived a nation’s gRLI values relying only on a representative subset of Cycads.
Important findings Using the equal steps method, the gRLI for Chinese higher plants, was calculated as 0.946 7 based on IUCN assessment data only, 0.908 2 based on the IUCN and Chinese endemic species assessments, and 0.540 1 using solely Cycas, respectively. The BIP approach, relying only on Cycads, underestimates gRLI for Chinese higher plants, suggesting a taxonomical bias. This study highlights the importance of incorporating data as comprehensive as possible to generate more accurate and reliable gRLI results. By calculating a gRLI for Chinese higher plants that is comparable to those of other countries, this study provides essential baseline data to support evaluation of China’s progress and efforts toward international commitments.
