1“三极对垒”还是“四分天下”——中国在全球科技中的新角色显示文摘美国与欧盟争夺世界科技领先者的竞赛是当前研究的热点。欧洲委员会最近的研究表明,欧洲在世界科技产出中所占的比重日益增加,并宣布欧洲上世纪末处于科学产出的领先地位。为了对全球发展态势进行监测,该研究对1991-2005年共15年的数据进行了分析。对科技产出活动和影响模式的分析采用的是一套文献计量指标和技术计量指标,这套指标包括:(1)出版物产出指标,如占世界总量的份额和基于主题的出版物分布概况;(2)引文指标,如基于期刊和基于主题的归一化平均引用率;(3)国际合作论文及其影响;(4)专利指标以及专利与论文之间的相互引用关系。同时文章还讨论了国家层面的文献计量学特征的演变、'科学权重'以及科学技术关联的模式。研究结果表明,采用科学技术指标这面镜子所反映的'三极对垒'模式在21世纪将不会长久,中国正在挑战一流科学经济强国的地位,并且其成为世界第二大科技强国的时代正在到来。Wolfgang Gl nzel Koenraad Debackere Martin Meyer 刘俊婉 2007科学观察2007,2,1:3
2Mapping mountain areas: learning from Global, European and Norwegian perspectives显示文摘Defining the spatial extent of mountain areas has long been a challenge. In the present century, the availability of digital elevation models(DEMs) incorporated into geographic information systems(GIS) has allowed the definition of mountain areas based on topographic and other criteria. This paper presents the various delineations of mountains that have been prepared at three scales – global, regional(Europe), and national – and explores the reasons and processes leading to these delineations, and how they have been used. A detailed case study is then presented for Norway. Overall, two types of approaches to mapping mountains have been taken: first, considering mountains per se, based on elevation and/or topography; second, considering them among other categories, e.g., landforms or biogeographical, environmental or landscape zones. All attempts to map mountain areas derive essentially from the objectives of those commissioning and/or undertaking the work; a unitary definition remains unlikely.Martin F.PRICE Tor ARNESEN Erik GL?ERSEN Marc J.METZGER 2019Journal of Mountain Science2019,16,1:3
