近五年中美地质调查局科研态势分析

Analysis of the R&D situation among CGS and USGS in the last five years

为了解中美两国地质调查局在科研态势方面的发展现状并比较其异同,进一步厘清中国与发达国家地质调查机构间存在的差距,本文采用文献计量学和社会网络的方法,以SCI-E、CPCI-S数据库中2013～2017年第一发文机构为中国地质调查局和美国地质调查局的学术论文为源数据,从发文量趋势、学科分布结构、研究前沿和热点、学科发展脉络、机构合作情况等方面统计分析两国地质调查局的特征并进行比较。研究结果表明:2013～2017年间,中国地质调查局发文总量呈现大幅增长趋势,美国地质调查局则呈现稳中有升的趋势,但美国地质调查局研究影响力较中国地质调查局具有较大优势。中国地质调查局在研究领域和热点方面对基础地质学、资源型地球科学学科关注度较高;而美国地质调查局则对气候变化等与生态环境和自然灾害相关的新型地球科学学科关注度较高。在国际合作和机构合作方面,中美两国地质调查局均与发达国家大学机构合作活跃,而中美两国地质调查局由于研究侧重点不同合作并不多。

Aim to mast the gap of CGS and other the developed countries,we analyze the R&D situation among CGS and USGS by using the methods of bibliometric and social network.We collect bibliometric data of papers published from 2013 to 2017 by authors from CGS and USGS in SCI-E and CPCI-S,and summarize the developing trends of papers,the distribution of the subjects,the international cooperation and cooperative network of organizations and the research hotspots.The results show that from 2013 to 2017,the total published papers of CGS showed a significant growth trend,while that of USGS showed a stable and rising trend.However,the academic influence of USGS has a greater advantage than that of CGS.CGS paid high attention to basic geology and resource-based geosciences studies in research fields and hot spots,while USGS was more concerned about new geosciences studies such as climate change related to ecological environment and natural disasters.In terms of international cooperation and institutional cooperation,both CGS and USGS had active cooperation with institutions of universities in developed countries.However,due to different research focuses,CGS and USGS did not have much cooperation.
