基于文献计量的土壤有机碳与土壤微生物多样性研究前沿态势分析

为了系统了解国际上土壤有机碳与微生物多样性的研究进展,基于Web of Science数据源,利用Web of Science数据库分析工具和Thomson Data Analysis(TDA)、社会网络分析与可视化工具Netdraw和Ucinet,从论文年度变化趋势、全球研究实力国家、机构分布和力量比较、基金资助机构和主题分布、机构合作和研究内容等方面,对1992~2015年的相关论文,尤其是近10年来土壤有机碳及其影响因素的相关文章进行计量分析。结果表明:(1)论文数量呈逐年增长态势,土壤有机碳与土壤微生物多样性研究主要集中在欧美发达国家(地区);美国和德国综合影响力最高,英国、瑞典、瑞士、荷兰论文篇均被引较高,以中国科学院为代表的中国机构在该领域研究增长较快,研究论文最多,但论文整体质量有待提高。(2)中国国家自然基金资助机构产出论文最多;美国国家科学基金会资助论文篇均被引最高,其次是德国研究基金会,中国科学院科学基金名列第3,各国在共同资助的研究主题基础上,各有其特色主题;美国的一些研究机构是全球该领域研究合作交流的中心,其次是德国和中国中科院。(3)土壤有机质、土壤有机碳、凋落物分解、氮、磷、微生物生物量、土壤性质、气候变化、碳固定是该领域10年来的热点研究主题。未来应加强国际合作研究,关注土壤重金属、凋落物分解和微生物呼吸等相关主题,以提高我国研究水平,将相关研究成果及时应用于解决相应的实际问题。

Frontier Situation Analysis of the Research on Soil Carbon Sequestration and Soil Microbial Diversity Based on Bibliometric

In order to understand the research progress of soil carbon sequestration and provide references data for relative researchers,this paper used the methods of Web of Science DSN and data base with build-in profiler Thomson Data Analysis (TDA),Society network analysis and visualization tools Netdraw and Ucinet,progressed the metric analysis of papers on carbon sequestration and its influencing factors published from 1992-2015,especially in recent decade,from six aspects as annual change trend of thesis,global powerful countries in relative research,organization distribution and force comparison,grant-giving agency and their theme distribution,institute cooperative and research content.The results showed that:(1) The number of papers was on a steady growth trend.The researches of soil carbon sequestration and soil microbial diversity mainly were focused on Europe and the United States and other developed countries (regions).The highest comprehensive influence of paper was occurred in United States and Germany.Higher citations per paper was mainly in Britain,Sweden,Switzerland,and Netherlands.The most research papers in this field were published by Chinese research institutions represented by Chinese academy of sciences.(2) The highest cited papers were mainly supported by National Science Foundation,followed by German research foundation,and Chinese academy of sciences foundation.Each country had their own special research theme based on public economic support.Some research institutions in America were the center of global research cooperation and communication in this field,followed by in Germany and Chinese academy of sciences.(3) Soil organic matter,soil organic carbon,nitrogen,phosphorus,microbial biomass,soil properties,climate change and carbon fixation had become hot research topics in this field in recently 10 years.Future research should focus on the topics on litter decomposition,heavy metals,microbial respiration,and strengthen international cooperation in order to improve Chinese research level and solve practical problems with the relative research achievement.
