湖南云山野生药用草质藤本植物资源调查研究

通过野外实地调查、标本采集和逐一考证的方式,对湖南云山野生药用草质藤本植物资源进行研究。结果表明:湖南云山共有野生药用草质藤本植物18科41属69种,分别占该区藤本植物科、属、种的36.73%、32.54%和17.21%,其中双子叶藤本具有明显的优势,单子叶藤本处于次要地位。在种群组成中,科的构成比较集中,属的构成相对分散。在攀援方式上,缠绕藤本具有优势,占总种数的66.67%,卷曲类、搭靠类和吸固类较少,分别占总种数的20.29%、8.70%和4.35%。在药用部位上,以根、全株和根茎的药用藤本植物最多,分别占有57.97%、44.93%和23.19%。在药用功效上,以祛风湿、活血化瘀和清热类最多,分别占30.34%、43.48%、40.58%。同时,对云山野生药用草质藤本植物资源的保护和开发利用提出了建议,以期为该地区野生药用藤本植物资源的可持续利用提供参考依据。

Investigation on Wild Medicinal Herb Liana Resources in Yunshan of Hunan Province

We studied the wild medicinal herb liana resources in Yunshan of Hunan by means of field survey,collection of specimens,and one-by-one investigation. The results showed that there were 69 wild medicinal herb liana species in 41 genera and 18 families in Yunshan,respectively accounting for 17. 21%,32. 54% and 36. 73% of species,genus,and family number of all lianas in this region. Among wild medicinal herb liana resources,the dicotyledonous lianas had obvious advantages,while mono-cotyledonous lianas were in a secondary position. As for population structure of wild medicinal herb liana,family composition was relatively centralized,and genus composition was comparatively decentralized. In terms of climbing style,the twining liana species were dominant,accounting for 66. 67% of overall species;while the curling,hooking and adhering liana species were few,account-ing for 20. 29%,8. 70% and 4. 35% of overall species,respectively. In terms of medicinal parts,the root-based,entire-plant-based and rhizome-based medicinal liana species accounted for 57. 97%,44. 93% and 23. 19% of overall species,respective-ly. In terms of medicinal effects,antirheumatic,blood -circulation -promoting and antipyretic medicinal liana ranked the top three,accounting for 52. 21%,50. 00% and 45. 22% of overall species,respectively. At the same time,some suggestions for the protection and utilization of wild medicinal herb liana resources in Yunshan were put forward,for the sake of providing a reference basis for the sustainable utilization of wild medicinal herb liana resources in this region.
