青海省唐古特铁线莲生物学特性的研究

Studies on Biological Characteristics of Clematis tangutica in Qing-hai Province

唐古特铁线莲是青藏高原一种重要的野生药用植物,全草可以入药,其中植株所含的皂甙类化合物具有十分重要的经济价值和药用价值.但由于过渡开采,使得该野生植物资源量呈显著下降趋势,这对于青藏高原的生态环境保护及药用植物的开发利用都是不利的.本文采用野外定点法、和最小样方法分别对青海省唐古特铁线莲的生物学特性和群落数量特征进行研究,旨在为青海省唐古特铁线莲资源的保护和合理开发利用提供科学依据.

Clematis tangutica （Maxim.） Korsh is a kind of important wild medical plant in Qing - Tibet Plateau. The whole plant is the medicine. Thereinto, steroidal saponins contained in the whole plant has the very important economic and medical value. But the resource of wild plant decreases markedly because of excessively exploration. That is detrimental to ecological environmental protection of Qing - Tibet Plateau and sustainable utilization and exploitation of medical plant. This article, applying the method of the pointing field and the least sample, studied biological characteristics, respectively populated botanical characteristics, and community and quantity characteristics of Mentha haplocalyx Briq. in Qing--hai Province. It provided scientific basis for utilization and exploitation of Mentha haplocalyx Briq. in Qing-- hai Province.
