Distribution pattern of traditional ecological knowledge on plant utilization among major minority peoples in Guizhou, China

ABSTRACT

In this study, the traditional ecological knowledge (TEK) on non-cultivated plant utilization by the Miao and Buyi people in Guizhou, China, was investigated using semi-structured interviews and the joint plant and use (JPU) was used as an index of TEK. In addition, the regional TEK distribution patterns were depicted. The results showed that low-frequency JPUs accounted for a large proportion of the total TEK on non-cultivated plant utilization, implying a possible TEK loss. The TEK distribution pattern is similar to the 80/20 rule, indicating that most TEK is mastered by key informants who are important for regional TEK protection and inheritance. Different informants have different JPU amounts and diversities with specific relationships, and for the characteristic ethnic TEK, medicinal JPUs generally have a low frequency, while symbolic JPUs have a higher frequency. The results could provide references for regional sustainable development and biocultural diversity management.
