科学会聚是21世纪世界科学发展的趋势和选择。以SCI和SSCI数据库中“气候”研究主题文献为例,借助信息可视化软件和技术手段,绘制了学科可视化知识图谱,分析了会聚科学发展过程中的学科发展趋势。结果表明,全球气候研究分布于自然科学、社会科学、人文科学和跨学科等多个学科门类;气候研究的论文产出接近于指数增长趋势,学科数量接近于线性增长趋势。研究结果对科技人力资源的配置、高等教育人才的培养具有一定启示。

The convergence of science is a natural tendency and a sure choice for the development of science worldwide in the 21st century. Taking as examples the climate-related literature in the data banks of both SCI and SSCI, and applying the newly-emerged visualized information software and technical means, the paper obtains visualized subject-specific maps of knowledge domains, which may be used to analyze the development trend of disciplines in the evolution of the converging science. As indicated by the analysis, the subject distribution of global climate researches covers many disciplines including the natural sciences, the social sciences, the humanities, and other cross-cutting subjects. The number of climate-related papers increases sharply, and the number of subjects is also in gradual increase. The research results would be remarkably indicative to the allocation of S&T human resources and the fostering of talents in higher-learning institutions in China. Some further and in-depth studies are required in the micro level.
