Qinghai Tibet Plateau

Advanced developments have been achieved in urban human population estimation, however, there is still a considerable research gap for the mapping of remote rural populations. In this study, based on demographic data at the town-level, multi-temporal high-resolution remote sensing data, and local population-sensitive point-of-interest (POI) data, we tailored a random forest-based dasymetric approach to map population distribution on the Qinghai–Tibet Plateau (QTP) for 2000, 2010, and 2016 with a spatial resolution of 1000 m. We then analyzed the temporal and spatial change of this distribution. The results showed that the QTP has a sparse population distribution overall; in large areas of the northern QTP, the population density is zero, accounting for about 14% of the total area of the QTP. About half of the QTP showed a rapid increase in population density between 2000 and 2016, mainly located in the eastern and southern parts of Qinghai Province and the central-eastern parts of the Tibet Autonomous Region. Regarding the relative importance of variables in explaining population density, the variables “Distance to Temples” is the most important, followed by “Density of Villages” and “Elevation”. Furthermore, our new products exhibited higher accuracy compared with five recently released gridded population density datasets, namely WorldPop, Gridded Population of the World version 4, and three national gridded population datasets for China. Both the root-mean-square error (RMSE) and mean absolute error (MAE) for our products were about half of those of the compared products except for WorldPop. This study provides a reference for using fine-scale demographic count and local population-sensitive POIs to model changing population distribution in remote rural areas.

Bon Religion is the original religion of the Qinghai-Tibet Plateau. Today there are still Bon beliefs or cultural phenomena influenced by Bon Religion in areas where Tibetans live. This is an important content of Tibetology research today. Predecessors’ research on Bon Religion mainly focused on three major issues: the birth of Bon Religion, the historical staging of Bon Religion, and the relationship between Buddhism and Ben religion. Many results have been achieved. However, these are far from enough in terms of the research value of Bon Religion itself. The research on the time and place of the birth of Bon Religion has not yet been concluded. The main results are concentrated on the research of macroscopic issues, and the research on specific issues is insufficient. In response to these issues, researchers should pay attention to the re-discussion of existing results, use the method of combining literature and field investigations to pay more attention to specific regional issues, and at the same time strengthen the use of multiple languages.
