摘　　要：将重庆特有极小种群植物缙云黄芩Scutellaria tsinyunensis为评估对象,以其生存现状及近年来衰退趋势为基础,依据《IUCN红色名录等级和标准》及在地区水平上的应用指南和中国极小种群野生植物濒危程度评价指标体系对其濒危等级进行了评估.结果表明:前者濒危等级为极危(CR),后者濒危等级为Ⅳ级濒危,与物种现行无危等级存在较大差异.该研究为缙云黄芩的濒危等级评定及实施有效保护策略提供了科学依据.Scutellaria tsinyunensis is an endemic species with extremely small populations in Chongqing. Based on the living situation and declining trend in recent years, the endangered levels of S. have been evaluated by IUCN red list categories and criteria and user guide and evaluation index system of endangered levels of the wild plants with extremely small populations in China. The result indicates that S. has been evaluated as Critically Endangered （CR）. And with the help of the evaluation index system, S. has been evaluated as highly endangered （IV level）. There is great difference between the results and present least concern （LC） level. The study provide a scientific basis for the evaluation of endangered levels on S. and implementation of effective protection strategy.
