摘要: 利用标本馆的标本信息, 根据物种分布区、占有面积、亚居群数及分布点数目等量化参数, 按照IUCN濒危等级和标准, 对囊瓣芹属(Pternopetalum) 6个种的受威胁程度进行了评估。结果表明: 薄叶囊瓣芹(P. leptophyllum)为极危, 川鄂囊瓣芹(P. rosthornii)为濒危, 东亚囊瓣芹(P. tanakae)、五匹青(P. vulgare)、洱源囊瓣芹(P. molle)和澜沧囊瓣芹(P. delavayi)为易危。在涉及大的空间范围和大量物种的评估实践中, 标本数据是最重要, 有时甚至是唯一的获取量化参数的依据, 但标本数据自身局限性造成的量化参数估计偏差对评估的影响还需要更深入的研究。

Abstract: Based on parameters established by the IUCN red list, including extent of occurrence, area of occupancy, numbers of subpopulations and location, we investigated the extinction risk of six species from the genus Pternopetalum. Our results indicated that the six species are threatened; P. leptophyllum is critical endangered, P. rosthornii is endangered, and P. tanakae, P. vulgare, P. molle and P. delavayi are vulnerable. For IUCN red list assessment, herbarium specimens are most important, sometimes an only data source, in getting quantitative parameters. It is practically an irreplaceable data source when assessment activity covering large scale area and huge species number. However, herbarium specimen bear with innate bias in estimating quantitative parameters, which resulted effect for assessment need further study.
