甘肃省第四次与第三次全国中药资源普查药用植物资源物种变化及成因分析

Species Change and Its Causes of Medicinal Plant Resources in the Fourth and Third National Survey of Chinese Materia Medica Resources in Gansu

通过对比第四次与第三次全国中药资源普查物种变化情况发现,第四次全国中药资源普查甘肃省新增了22科309属2072种,其中包括新分布种37种;消失或未调查到的药用植物资源有187种,隶属于87科158属。探究了时隔40年甘肃省药用植物资源物种变化的成因,表明此次普查从技术方法、仪器设备、人员组织、调查范围、顶层设计等各个方面都有了极大的改进和提升,使本次普查药用植物资源物种数大幅增长;生态环境的变化使得部分物种分布区狭小,或处于濒危状态,或生在悬崖峭壁。这是导致部分物种漏采漏查或未调查到的重要原因。通过分析物种变化情况,为该省药用植物资源保护与开发利用提供参考。

This paper compared the medicinal plant resources in Gansu Province between the Fourth and Third National Survey of Chinese Materia Media Resources.Compared with the third survey,the fourth survey additionally identified 2072 species belonging to 309 genera of 22 families in Gansu,including 37 new species.There were 187 species of medicinal plants disappeared or not investigated,belonging to 158 genera of 87 families.This paper explored the causes of species changes of medicinal plant resources in Gansu over the past 40 years.The improved technology,equipment,and top-level design,increased staff,and expanded survey scope substantially increased the number of medicinal plant species identified in the fourth survey.The change of eco-environment narrowed the habitats of some species and the habitat being cliffs are major reasons for the missed survey of some species.This study can provide reference for the protection,development,and utilization of medicinal plant resources in Gansu.
