云南省澄江县药用维管植物多样性及保护利用初探

Diversity and Conservation of Medicinal Vascular Plants in Chengjiang County of Yunnan Province

根据云南省第四次中药资源普查项目编制的《澄江县药用维管植物名录》,对县域内药用维管植物的种类、生活型、种子植物属的区系特征、珍稀濒危物种和药用部位等做统计分析。结果显示:澄江县药用维管植物有122科416属645种;种子植物属的分布区特征为热带比温带成分略少,表现为亚热带区系;珍稀濒危植物20种,包括11种兰科,4个中国特有种;生活型以多年生草本为主,有236种;药用部位多为根茎及全草入药,共占药用植物的67.01%。结合当地自然地理条件和经济发展需求,基于澄江县野生药用植物多样性特点,初步探讨药用植物资源的保护和可持续利用发展的方向。

Based on the list of medicinal plants in Chengjiang County obtained by the 4th National Survey of Chinese Medicine Resources,the characteristics of medicinal plant diversity was analyzed,including species,the geography distributing type of seed plants,rare and endangered plants,life forms,and usage of plants.The results showed that there were 645 species of 416 genera from 122 families recorded in Chengjiang.Subtropical floristics were dominant in 14 Aerial-types of genera of seed plants due to the similar numbers of tropical and temperate types.There were 20 species of rare and endangered medicinal plants,including 11 orchids and 4 species endemic to China.In five life-forms,perennial herbs medicinal plants were the most popular with a larger number of 236 species.The medicinal plants used with roots and whole plants were accounted for 67.01% of the total number.Considering local natural geographical conditions and current demand of economic development,this preliminary research on medicinal plants in Chengjiang should provide a better understanding of conservation of biodiversity in this county.
