气候变化风险是全球各国所关注的焦点问题，不同地理环境和经济社会条件促成了多样化的风险评估内容和技术。目前，气候变化风险评估是一个多学科交叉的研究领域，集结了不同门类科学知识。本文基于 Science Citation Index Expanded(SCI-E)和 Social Sciences Citation Index(SSCI)网络数据库，利用文献计量方法，分析了气候变化风险评估研究的发展变化特征和趋势，研究结果表明：气候变化风险评估的科研产出量在不断快速增长，美国在此领域占据领先地位，而英国University of Oxford和University of East Anglia是主要研究机构；现有研究集中在自然科学方面，社会科学内容较为缺乏；总体来看，作者和机构层面的合作研究正在不断加强。同时，中国在气候变化风险评估方面的科研产出量显著增加，累计发文数列世界第10位；中国科学院是全球重要的研究机构之一，但所发表论文的被引频次偏低。此外，本文通过词频分析归并形成了此领域内的9类研究热点，包括脆弱性、自然灾害、水资源、农业、生态、健康、社会经济、决策分析和模型方法。它们的时间分布特征表明，脆弱性、生态和社会经济是近期受关注度较高的3个方面。
英文摘要:
Climate change is the hotspot concerned by every country of the world, and different geographical and socio-economic conditions bring about various contents and technologies of risk assessment. At present, climate change risk assessment has developed into an interdisciplinary field built on comprehensive scientific knowledge. On the basis of the Science Citation Index Expanded (SCI-E) and Social Sciences Citation Index (SSCI), this paper presents the development characteristics and trend of the studies on climate change risk assessment by a bibliometric analysis. The results suggest that: (a) the scientific outcomes of climate change risk assessment are increasing sharply with the greatest contribution made by the U. S., and the University of Oxford and the University of East Anglia are two predominant research institutions; (b) there are much more studies focusing on physical science than social science; (c) overall,the author, institution and country collaborations are becoming stronger. Especially, China's outcomes are increasing, ranking No. 10 in the world. And Chinese Academy of Sciences is one of the most important research institutions, however,the times cited of its publications are low. Additionally, 9 hot issues are summarized by keyword analysis including vulnerability, natural disaster,water resources,agriculture,ecology, health, economy & society,decision making,and modelling. Their temporal patterns imply that more attention is being paid to vulnerability,ecology and economy & society.
