随着天然药物和天然保健品的流行，药用植物资源枯竭的问题日益凸显。我国药用植物的保护日益受到重视，但是目前的药用植物保护评估方法还存在不足。在总结植物受威胁程度和优先保护评估方法的基础上，根据药用植物迁地保护数据特点对现行的药用植物受威胁程度及保护优先等级方法进行了改进，并对分级抽取的10种中药材进行了比较研究。结果表明，本方法与原方法的评估结果存在差异，且新方法在指标灵敏度、数据获取容易程度、批量评估等方面有进一步的提升，能较好地反映物种优先保护程度，对中药资源经济研究和管理具有参考意义。

With the prevalence of natural medicine and natural health products, the problem of resource exhaustion of medicinal plants have become increasingly serious. The protection of medicinal plants in China is increasingly valued, but there are still some shortcomings in the current assessment methods of medicinal plant protection. Based on the summary of evaluation methods of threatened level and priority protection of plants, this paper improved the existing methods according to the characteristics of ex situ conservation data of medicinal plants, and performed comparison study on ten hierarchical selected medicinal plants. The results showed that there was a difference between new method and the original method, and this method could further improve the index sensitivity, ease of data acquisition, and batch evaluation, which can better reflect the priority of species protection. The method can be used for assessing ex situ conservation of medicinal plants and has reference meaning for the economic research and management of Chinese materia medica resources.
