摘要: 采用大数据方式,通过对Web of Science核心平台全球变化研究数据进行文献采集、存储、挖掘和关联分析,探究全球变化领域的研究趋势、研究力量、学科布局以及领域的重点与热点。该领域在此平台共检索到145 849篇论文,年发文量总体呈快速增长趋势。美国在发文量、总被引频次上远远超过其他国家,中国科学院以5 815篇发文量在所有研究机构中排第一。全球变化研究主要分布在环境科学与生态、地学、气象学与大气科学等学科。全球变暖、温室气体效应、碳氮循环、生物多样性保护、可持续发展等为该领域主要研究内容。遥感、卫星、模型、GIS等是主要研究手段。

Abstract: To investigate the develop trends and the hot spots of the global change research, we used TDA analyzer to data mining based on WOS (Web of science) core collection database. We found that the annual number of publications increased rapidly in recent years, and a total of 145 849 papers were published in this field. The numbers of publications and citations in USA were far higher than those in other countries. However, the Chinese Academy of Sciences published 5 815 papers and was in the first rank of all the institutions. The research areas in the global change are mainly in environmental science and ecology, geography, meteorology, and atmospheric science, focusing on global warming, greenhouse gas effect, carbon and nitrogen cycle, biodiversity conservation, and sustainable development by using remote sensing, satellites, models, and GIS.

Key words: TDA, ecology, global warming, carbon, nitrogen
