大围山国家级自然保护区药用植物资源及其多样性研究

为深入研究云南东南部药用植物资源的分布和多样性,对云南大围山国家级自然保护区药用植物资源作了系统调查.保护区有药用植物资源205科、792属、1 607种,分别占大围山植物资源科、属、种数的86.1%,67.0%和41.3%.药用植物资源中,有26种是国家级的稀有濒危保护植物,占国家珍稀濒危药用植物种数的15.4%;云南省级重点保护的药用植物9种.全株和根及根状茎的药用植物最多,占75.5%,提醒我们采挖时必须兼顾到资源的更新,保护好资源的再生性,做到可持续利用.

Medicinal plant resources and their diversity in Mountain Dawei National Nature Reserve in Yunnan, China

In 1997 and 1998 a systematic survey was conducted in the Mountain Dawei National Nature Reserve in the Yunnan Province, southwestern China. Some 1 607 species of medicinal plants belonging to 792 genera and 205 families were found in the Mountain Dawei, which accounted for 41 3%, 67 0% and 86 1% of the respective species, genera and families of plant resources there. There were 26 species of endangered plants under the national protection, which accounted for 15 4% of the endangered medicinal plants in China. And there were 9 species of medicinial plants under the provincial protection of Yunnan. Most of the plants, occupying 75 5% in this area, can be used as medicinal materials. Among which some as a whole plant have medicinal value, and for some others only the roots or rootstocks have such value. This suggests that moderate collection is necessary for the purpose of sustainable utilization and the protection of resource regeneration.
