药用植物多样性特征分析——以陕北米脂县为例

Analysis of diversity in medicinal plant resources: Taking Mizhi county in northern Shaanxi as an example

  • 摘要: 为研究陕北米脂县野生药用植物资源现状及其分布规律,通过野外调查及查阅文献等方法,对该地区药用植物多样性及其特征进行研究。结果显示:(1)米脂县共有野生药用植物45科110属148种,其中裸子植物2科2属2种、被子植物43科108属146种,集中分布于单种科和寡种科及单种属内;(2)从生长型来看,草本植物最多,其次是乔木,灌木最少;(3)药用部位以全草类、根及根茎类最多,分别占药用植物总种数的52.03%和14.86%;(4)药用功效以清热和利水渗湿为主,分别占药用植物总数的23.65%和11.49%;(5)从药用植物属的分布类型来看,有13个分布区类型8个变型,区系成分复杂多样,温带性质明显。本研究表明米脂县药用植物资源多样性较高,生长型、药用部位、功效、区系成分丰富多样,明确了该地区野生药用植物资源的分布及生存现状,为加强资源的保护及开发利用提供了依据。

     

    Abstract: Based on field investigation and a literature review, the diversity and characteristics of wild medicinal plants were analyzed to study their current status and distribution in Mizhi County, northern Shaanxi Province, China. Results showed that:(1) There were 148 species of wild medicinal plants in Mizhi County belonging to 110 genera and 45 families, including two families, two genera, and two species of gymnosperms; and 43 families, 108 genera, and 146 species of angiosperms. The species were predominantly distributed in single-family, depauperate family, and single-genus; (2) In terms of growth form, there were more species of herbs than of shrubs and trees; (3) The most common parts used for medicinal materials were roots and rhizomes, accounting for 52.03% and 14.86% of total medicinal plants, respectively; (4) Most of the medicinal plants were used as antipyretics and for removing dampness and promoting dieresis, accounting for 23.65% and 11.49% of total medicinal plants, respectively; (5) There were 13 areal-types and eight subtypes of genera, the composition of the flora was complex and diverse, and the temperate nature was significant. This study shows that the diversity of medicinal plant resources in Mizhi County is high, with rich and diverse life forms, medicinal parts, functions, and areal-types. This study clarifies the distribution and survival status of wild medicinal plant resources in the area and could be used to strengthen the protection, development, and utilization of these resources.
