【摘要】 青藏高原是国际地球科学研究的热点区域之一,特别是进入21世纪以来,相关科研论文大量涌现。基于知识图谱(Mapping Knowledge Domain,MKD)和地理信息系统(Geographic Information System,GIS)技术对1900~2012年SCIE收录的青藏高原科研文献进行可视化展现和分析。计量指标分析结果显示青藏高原科研论文在21世纪初呈现井喷式增长,中国、美国、印度、加拿大和法国等国家是发文和被引的主要国家。知识图谱分析结果显示美国、英国、法国等国家对青藏高原的研究开始的比较早,影响较长远,中国,印度、日本等国家近年来对青藏高原研究的关注度较高、成果产出较多、当前影响力较大。开展合作研究较多的国家有中国、美国、日本等,多边国际合作研究呈快速上升趋势。GIS分析结果显示相关学科研究在空间分布上存在很大的差异性。以上结果可以为我国青藏高原的科研创新提供参考,并促进学科间的交叉、融合和发展。更多还原

【Abstract】 Qinghai-Tibet Plateau is one of the hotspots of the international earth science studies.The relative research papers have proliferated especially since 21 st century.By using the the bibliometric indicators,the statistical analysis of the quantities and qualities was carried out for the Qinghai-Tibet Plateau literature indexed by SCIE during 1900 and 2012.It focused on the published years,journals,countries,cities,research institutes,international cooperation,and subjects.Some statistical results were displayed and deeply analyzed by using the tools of Mapping Knowledge Domain(MKD) and Geographic Information System(GIS).The results of the Bibliometric analysis indicate that the publication and citation of QTP researches have a jump after entering the 21 st century.China,USA,India,Canada and France are the main coutries engaged in the Qinghai-Tibet Plateau studies.Knowledge mapping results show that USA,UK and France have longer academic influential power of QTP researches,which indicates that these countries begin to study QTP early and the papers have long-term effects.On the other hand,China,India and Japan have higher influential power in recent years,which indicate that these countries have more publications and higher impacts recently.The spatial analysis indicates that the differences of the disciplines are emphasized by different countries.The above analysis results are hoped to integrate the new knowledge and reveal the development tendency of the QTP researches.更多还原
