IPCC-AR5-WG I的学术影响扩散研究

鉴于联合国政府间气候变化专门委员会（IPCC）第五次评估报告（AR5）中第一工作组（WG I）的研究报告（IPCC-AR5-WG I）与科学研究的关联性更强、对科学研究的影响也最大，因此基于Web of Science引文数据库，通过科学计量法，利用描述性统计、空间分布分析以及网络分析等方法，分析IPCC-AR5-WG I的施引文献的时序、区域、机构合作以及主题领域等特征，以揭示其学术影响力及扩散情况。结果表明：IPCC-AR5-WG I在154个国家和地区的施引量呈逐年上升趋势，其中2021年出现爆发性增长；施引量最多的为美国、中国和英国，以美国、中国和欧洲的机构为代表形成了三大合作群，其中中国施引机构合作群的合作强度更高；施引文献广泛分布在182个学科领域中，呈现出多学科交叉影响的趋势；其包含扩散爆发期、突破发展期和交叉融合期等3个时期的学术影响力扩散主要分布在气候变化影响建模、温室气体排放与监测、气候变化对环境的影响以及遥感与极地气候变化四大领域，相关研究主题也呈现出由广泛到聚焦、由分散到融合的趋势。

Evaluation of the Impact of IPCC-AR5-WG I in Scientific Research

Since the IPCC AR5-WG I report was released in 2014, it has provided a framework guidance for human activities and scientific research. When IPCC-AR6 is released, a comprehensive assessment of the impact of IPCC AR5-WG I on scientific research is of great significance for understanding its role in scientific research. This study uses the Web of Science Citation Database to collect the citation title data of the IPCC AR5-WG I report, and comprehensively shows the value of the IPCC AR5-WG I report from the dimensions of time sequence, geographical region, institutional cooperation, academic influence and subject field. The research suggests that the cited amount of IPCC AR5-WG I shows an upward trend year by year, the cited regions and disciplines are widely distributed, the four fields of academic influence diffusion are coupled with each other, and the theme of academic diffusion shows a trend from wide to focus, from dispersion to integration in three stages, which has a certain reference value for the scientific research on the impact of policy reports in the future.
