Paper Abstract

The subject intersection becomes one of the hot research topics recently. It is a new direction to integrate the GIS technologies with Bibliometrics. The literatures concerned with geosciences normally involve some spatial related information. In this paper, the spatial information of the study area and sampling or observing points was extracted. Then these data were analyzed and presented by using the GIS technologies. The results indicate that there are big variations of the spatial distribution. For the whole Qinghai-Tibet plateau, the degree of interest increase as follow: southwest, northwest, southeast, and northeast. For the regions, Qilian Mountains, Qiangtang plateau, Qinghai-Tibet Road and Qinghai-Tibet Railway, Qinghai Lake, and Sichuan-Tibet Road are the hotspot regions. There are differences of the distribution characteristics in the different segments along the latitudinal direction and longitudinal direction. There is transfer tendency from middle Qinghai-Tibet Plateau to northern Qinghai-Tibet Plateau. Most of sampling and observing points are close to the traffic lines. The point numbers decrease quickly along with the increasing distance to the traffic lines.
