摘要
作为全球气候变化的主要推动因素之一,甲烷在三大温室气体中占据重要地位。因此,对甲烷排放通量的研究对于我们了解和预测气候变化的趋势具有不可忽视的作用。为了更好地理解和应对气候变化,我们采用了CiteSpace工具,对2013年至2023年期间在Web of Science和中国知网上发表的关于中国甲烷排放研究的1 620篇英文和1 206篇中文文章进行了文献计量对比分析。通过深入地对比和分析,我们总结出了甲烷排放研究的最新前沿、热点和趋势,期望这些发现能为甲烷排放的管理研究和气候变化趋势的研究提供有益的参考。对比分析结果显示,国内外的研究趋势存在一定的差异。总体来看,当前的研究热点主要集中在全球变暖因素、甲烷的来源及形成过程、湿地生态系统甲烷排放、牲畜水稻甲烷排放等方面。这表明,当前的研究热点主要集中在甲烷气体的来源和影响因素的研究上。基于以上发现,建议未来的研究应更加关注符合中国未来发展趋势、具有创新性的研究方向。同时,我们也需要继续加强对甲烷排放的影响因素和减排技术的研究,从而更好地应对气候变化带来的挑战。
As one of the major drivers of global climate change,methane plays an important role in the three major greenhouse gases.Therefore,the study of methane gas emission fluxes has a non-negligible impact on our understanding and predicting trends in climate change.To better under-stand and address climate change,we used the CiteSpace tool to conduct a comparative bibliometric analysis of 1620 English and 1206 Chinese articles published on methane emissions research in Chi-na in Web of Science and CNKI between 2013 and 2023.Through in-depth comparison and analy-sis,we summarize the latest frontiers,hotspots and trends of methane emission research,expecting that these findings will provide a useful reference for management studies of methane emissions and studies of climate change trends.The comparative analysis results show that there are some differ-ences in the domestic and foreign research trends.In general,the current research hotspots mainly focus on global warming factors,sources and formation processes of methane,methane emissions from wetland ecosystem,methane emissions from livestock and rice,etc.This indicates that the cur-rent research focus is mainly focused on the study of the sources and influencing factors of methane gas.Based on the above findings,we suggest that future research should pay more attention to inno-vative research directions that are in line with China's future development trend.At the same time,we also need to continue to strengthen research on the factors influencing methane emissions and e-mission reduction technologies to better address the challenges posed by climate change.
