Abstract:

Traditional knowledge (TK) related to the utilization of biological resources is a knowledge system for identifying and utilizing biological resources. With the development of modern biotechnology, TK highlights its values of science, economy, culture and even food security. In accordance with the Technical Regulations on Classification, Investigation and Documentation of Traditional Knowledge Related to Biodiversity (Trial Version), this study conducted the systematic investigation and documentation of the TK related to the utilization of biological resources by Tu nationality in different ethnic agglomeration areas in Qinghai Province, and applied biodiversity index to TK diversity analysis. The results show that: (1) 424 items of TK of Tu nationality’s utilization of biological resources have been documented. (2) The α diversity index (DTK) of TK of Tu nationality is 0.67, which indicates that the diversity of TK of Tu nationality is high; but the β diversity index of TK varies in different counties, indicating that the TK of Tu nationality has unique spatial distribution in different areas with uneven and patchy characteristics. This study applied biodiversity index to TK diversity analysis and verified with the TK of Tu nationality as an example. It could be concluded that the diversity index of TK could not only objectively and practically quantify the diversity of TK but also provide the fundamental basis for establishing a quantitative research methodology of TK in the future.

Key words: Tu nationality, traditional knowledge, biological resources, diversity index of traditional knowledge
