The multi-disciplinary cooperation and intersection becomes the main development tendency of the modern sciences. It is a new direction to expand the Geographical Information System (GIS) application areas by integrating the GIS technologies with Bibliometrics. A lot of geographic-related information is involved in the literatures concerned with geosciences normally involve some geo-science references. In this paper, the locationrelated information (e.g. study areas, sampling trips and sampling points) was extracted from the CNKI-indexed scientific literatures for QinghaiTibet Plateau. These data were spatially analyzed and presented by using the GIS technologies. The subject areas about the Qinghai-Tibet Plateau studies mainly focus on the ecological environment and its changes, geologicalgeophysical feature and evolution, natural resources and exploration, and geological engineering. The results indicate that there are big differences of the spatial distribution for Qinghai-Tibet Plateau researches. For the large scale, the degree of interest increases gradually as follows: southwest, northwest, southeast, and northeast. For the region scale, Qilian Mountains, Qiangtang Plateau, QinghaiTibet road and Qinghai-Tibet Railway, Qinghai Lake, and SichuanTibet Highway are the hotspot regions. There are also big differences along the latitudinal direction and longitudinal direction, which indicates a transfer tendency from middle to northern Qinghai-Tibet Plateau. Most of the sampling and observing points are close to the traffic lines. The sampling point numbers decrease quickly with the increasing distance to the traffic lines. It is also indicated that the GIS technologies are effectively used in bibliometrical analysis of Qinghai-Tibet Plateau studies, which is of benefit to us for mining a great deal of spatial relative information and analyzing the developing trends.
