Abstract:To preliminarily explore the composition and evolutionary patterns of Tibetan paper raw materials and sort out the basic research context of relevant research, this study analyzed seven ancient Tibetan paper residue samples with modern instruments, and conducted cross-validation in combination with data from 31 Tibetan paper documents spanning the 8th to 19th centuries,to explore the evolutionary characteristics and influencing factors of Tibetan paper raw materials. The results showed that the raw materials of seven ancient Tibetan paper residue samples fell into two categories: Daphne and mixture of Daphne and Stellera Chamaejasme, and the differences in raw materials of paper listed in the same sutra fascicle. The evolutionary timeline of Tibetan paper raw materials coincided with the transition from prosperity to decline of the Tubo dynasty, and such evolution was driven by the combined effects of three factors: frequent disasters, population mobility and demand for sutra copying, and vegetation degradation induced by overgrazing.
