民族植物学定量研究中的取样方法

Methodology of Sampling in Quantitative Ethnobotany

定量方法在民族植物学研究中越来越占有重要的地位 ,但民族植物学定量研究中有关取样方面还存在着一些不同的看法。笔者针对云南省金平苗族瑶族傣族自治县的拉祜族民间草医所使用的药用植物资源和草医对不同生境中药用植物的利用情况进行了取样 ,并以此对民族植物学中有关取样中存在的问题进行了讨论。结果表明 ,不同生境中民族植物学的取样面积与植物生态学中的取样面积比较相近。所以在进行民族植物学野外取样时 。

Quantitative methods have played more and more important role in Ethnobotanical researches. However, there is still much confusion in sampling methods. Based on our field work about medicinal plants in different habitats used by folk healers of the Lahu people in Jinping Miao, Yao and Dai Autonomous County, some problems existing in sampling methodology of Ethnobotany have been discussed in this paper. The results show that sample areas in different habitats in Ethnobotany researches are similar to that in Ecological researches. So in the same environment, sample area in ecological study may be used as an indicator for determination of sample area in Ethnobotanical research.
