多学科的协同、渗透、交叉已成为当代科学发展的重要趋势，文献计量学和地理信息系统（GIS）技术的集成是拓展GIS应用领域的一个新兴方向。许多与地理空间位置有关的信息包含在大量地学科研文献中。从CNKI文献数据库收录的研究青藏高原的科研文献中提取研究区、样带和采样点等位置相关信息，运用GIS技术进行空间分析和展现。结果显示，青藏高原研究的主要学科领域集中在生态环境及其变化、地质与地球物理特征及其演化、资源及其勘探、地质工程等方面。有关青藏高原的研究在空间分布上存在较大的差异，对青藏高原的研究从西南、西北到东南、东北区域，其受关注的程度逐渐增加。祁连山脉、羌塘高原、青海湖、青藏公路、青藏铁路和川藏公路等是研究的热点区域。沿经度和纬度方向不同区间研究的分布也不同，研究热点区域呈现出从青藏高原中部向东北部转移的趋势。多数采样点和观测点沿交通干线分布，并且随着与交通干线距离的增加数量明显减少。GIS技术在关于青藏高原的文献计量分析中得到了有效应用，有助于挖掘出大量与空间位置相关的信息，从而深入分析青藏高原研究的发展态势。

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.
