基于CiteSpace的温室气体监测发展动态可视化分析

采用文献计量方法，利用CiteSpace软件对Web of Science核心合集中2004—2020年以"Greenhouse Gases Monitoring"为主题词检索到的2 514篇文献进行可视化分析，从时间分布、国际合作、研究机构合作、研究领域、共被引分析和关键词分析等方面，揭示该领域的发展动态、研究实力分布、热点前沿等。结果表明：2004—2020年温室气体监测研究领域的发文数量总体呈现上升趋势，在全球应对气候变化的重大事件时间节点发文数量增幅较大；该领域发文量较多的国家和机构皆以发达国家为主，发展中国家中中国居首位，国家、机构合作关系紧密；温室气体监测研究涉及的学科领域较广，环境科学与生态学、环境科学、工程为排名前3位的学科领域，2010年后研究逐步拓展到建筑学、影像学、计算机科学、经济学等领域；该领域的研究知识基础主要聚焦温室气体浓度监测、来源去向、影响因素及变化趋势分析，温室气体监测技术方法研究及应用，以及森林、农业土壤碳汇研究等方面；通过不同时段关键词分析发现CO₂、CH₄和N₂O一直是温室气体监测研究的重点对象，关注视角逐渐转向多因素、多领域、多技术、多方法、多策略研究。基于分析结果和中国实际，提出今后一段时期中国温室气体监测领域的研究重点和工作方向。

Visualization Analysis on Development Trend of Greenhouse Gas Monitoring Based on CiteSpace

This study used bibliometric method and CiteSpace software to visually analyze the 2514 papers on greenhouse gas monitoring topics in the Web of Science during 2004-2020,from the aspects of time distribution,international cooperation,research institution cooperation,research field,co-citation and keyword analysis,in order to reveal the development trends,research strength distribution,and hotspots in this field.The results showed that the number of publications of greenhouse gas monitoring research from 2004 to 2020 showed an overall upward trend,and the number of publications increased significantly at the time of major events about climate change.The countries and institutions with a large number of publications were mainly developed countries,China was leader among developing countries,and the cooperation among countries and institutions was close.Greenhouse gas monitoring research involved a wide range of disciplines,and environmental science and ecology,environmental science,and engineering were the top three disciplines.Since 2010 the research gradually expanded to the fields of architecture,imaging,computer science,economics,etc.The research knowledge mainly focused on greenhouse gas concentration monitoring,source and destination,influencing factors and trend analysis,greenhouse gas monitoring technology research and application,and research on carbon sequestration of forests and agricultural soils.It was found that CO₂,CH₄ and N₂O had always been the key objects of greenhouse gas monitoring through keyword analysis,the attention perspective had gradually shifted to multiple factors,multiple fields,multiple technologies,multi-method,multi-strategy research.Based on the analysis results and actual situation in China,the future research focus and direction of greenhouse gas monitoring were proposed.
