Abstract： The loss of biodiversity not only means the loss of genes, species and ecosystems, but also threatens the cultural diversity. Thangka is known as the ‘encyclopaedia’ of traditional Tibetan culture, covering social, historical, cultural, religious and medicinal aspects. Qinghai Regong Thangka is one of the most important sects of Thangka, which have vivid and delicate depiction of images, and the numerous depictions of natural landscapes. By combining the methods of literature analysis, work analysis and ethnobiological fieldwork, the biocultural aspects of Regong Thangka are studied in terms of the traditional knowledge related to biodiversity in the painting techniques of Regong Thangka and the analysis of the connotation of biological images. The results were as follows: The study revealed the biological origins and production processes of the traditional painting tools and 12 natural plant-derived pigments for Regong Thangka; explored the origins and functions of the biological images often found in the Thangka works; explained the ecological concepts conveyed from Regong Thangka. In general, Regong Thangkas are not only resulted from nature, but also provide feedbacks to nature in their content. In the future, we should pay attention to the protection and inheritance of the traditional skills and biodiversity related traditional knowledge of Regong Thangka, and further explore its functions of traditional knowledge dissemination and nature education.

Abstract： Angiopteris esculenta is one of the most important wild substitutes for staple food in Dulong’s communities (the least populated ethnic group in Yunnan Province, China) for centuries. For a long time, the Dulong people collect the underground parts of A. esculenta to extract flour and make into food. In order to study and record the traditional knowledge of Angiopteris esculenta, and reveal the scientific basis of this plant consumed by Dulong people, ethnobotanical methods were employed to investigate and document the traditional knowledge about A. esculenta. Approaches of food science were used to reveal the basic components, appearance, physical and chemical properties, and gelatinization characteristics of A. esculenta flour in the present paper. The results were as follows: (1) A. esculenta is a multipurposed plant in the traditional livelihood of Dulong people. Local people employed this plant for edible purpose, medicinal purpose, ornamental purpose and woody purpose. Quantitative analysis showed that the relative frequency of citation (RFC) of the edibleness was much higher than that of other uses, which shows its main way as staple food. (2) The traditional uses of fern flour extracted from the underground part of A. esculenta imply rationalities. There is high starch content in the flour, and the total starch content is 86.2%. A. esculenta flour contains various mineral elements necessary for human body. (3) The flour has good physical and chemical properties, specifically, the retrogradation and freeze-thaw stability are strong, which can be used in the production and process of frozen food and starch products. The regeneration value and attenuation value of starch were much lower than that of common starch, which indicated that it had good stability of hot paste and cold paste, and not easy to regenerate, thus imply the good processability in food industry. The research results of the physical and chemical properties provide a theoretical basis for the subsequent processing and utilization of A. esculenta. In conclusion, A. esculenta flour has a good potential for utilization and further development. It is expected to play a positive role for increasing local residents’ income and for rural revitalization in remote areas, through the approaches of artificial cultivation.

Abstract：瑶族民间药浴历史悠久，是重要的疾病预防和治疗手段，是我国重要的非物质文化遗产。江华瑶族自治县药浴植物丰富，药浴配伍独具当地特色。本研究采用民族植物学方法对湖南江华瑶族自治县瑶族传统利用的药浴植物进行了调查。共收集整理了152种药浴植物，隶属于70科125属，记录了其瑶名、学名、入药部位以及功能主治等。并调查记录了部分常用药浴与产后药浴植物配伍。结果表明：江华瑶族药浴植物中草本植物占明显优势，且多为全草入药，主要用于治疗风湿关节炎、跌打损伤、妇科病以及皮肤病等，常用的药浴植物多为祛风除湿的“风药”；同时，通过实地调查和访问调查发现，珍贵药浴植物种群规模因过度采挖和生境破坏而减小；对比了广西、云南、湖南等地区瑶族药浴植物的异同，探讨其背后的相关性和原因。作为非物质文化遗产的瑶族药浴面临诸多方面的威胁，其内部科学性仍有待探究，需进一步加强综合研究与合作，为其保护、传承和发扬提供保障。
