Evaluation methods and empirical study on priority species for ex situ conservation of medicinal plants / 中草药

ABSTRACT

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.
