基于文献计量分析的土壤固碳研究进展

Research Progress on Soil Carbon Sequestration Based on Bibliometric Analysis

    摘要
  • 摘要: 为了解国内外土壤固碳的相关研究前沿与进展，本文基于 Web of Science核心数据库与CNKI数据库，利用文献计量分析方法对领域内的研究现状、研究热点和前沿趋势进行了分析。研究结果表明：关于土壤固碳研究的发文量整体呈上升趋势，且近几年增幅较大。美国的发文量及发文期刊的影响力均较高。从国际合作水平来看，中美两国的合作较紧密，对该研究领域的贡献最大，中国科学院、俄亥俄州立大学和美国农业部农业研究局具有较高的国际影响力，而国内影响力较强的机构有中国科学院生态环境研究中心、南京农业大学和中国科学院南京土壤研究所。国际上主要发文期刊有Agriculture Ecosystems & Environment（农业生态与环境）、Soil & Tillage Research（土壤与耕作研究）、Global Change Biology（全球变化生物学），国内生态学报、生态环境学报和应用生态学报发文量较多。从学科分布来看，国际土壤固碳研究涉及的学科主要有环境科学、土壤科学和生态学；国内主要集中在农学与林学。国际研究热点关键词包括“organic matter”（有机物）和“nitrogen”（氮），研究前沿是“Greenhouse gas emission”（温室气体排放）和“Nitrous oxide emission”（一氧化氮排放）对土壤固碳的影响；国内主要的研究热点关键词是“土壤有机碳”和“固碳”，“群落结构”（特指土壤微生物）对土壤固碳的影响是目前的研究前沿。

     

    Abstract: In order to understand the frontiers and progress of research on soil carbon(C) sequestration at home and abroad, the core database in Web of Science (WOS) and the journal database in China National Knowledge Infrastructure (CNKI) were taken as the data sources. Using bibliometric analysis method and CiteSpace software, the research results on soil C sequestration were summarized. The number of publications on soil C sequestration research at home and abroad was generally on the rise, especially in recent years. The number of publications and the influence of published journals in the United States were much higher than those in China. From the perspective of international cooperation level, China and the United States had the closest cooperation and made the greatest contribution to this research field. Among research institutions worldwide, the Chinese Academy of Sciences, Ohio State University and the United States Department of Agriculture Agricultural Research Institute had the greatest influence, and the domestic institutions including Research Center for Eco-Environmental Sciences of Chinese Academy of Sciences, Nanjing Agricultural University and Institute of Soil Science of Chinese Academy of Sciences had the strong resesrch capabilities. The main international journals on soil C sequestration research included Agriculture Ecosystems & Environment, Soil & Tillage Research, and Global Change Biology, and the main domestic journals included Acta Ecologica Sinica, Ecology and Environmental Sciences and Chinese Journal of Applied Ecology. Environmental Science, Soil Science and Ecology were the top 3 disciplines of international research on soil C sequestration. And the domestic research disciplines on soil C sequestration mainly focuseds on agronomy and forestry. In terms of research hotspots and cutting-edge trends, the main international research hotspots were “organic matter” and “nitrogen”. The frontiers of research were greenhouse gas emission and nitrous oxide emission. Soil organic C and C sequestration were the most important research hotspots in China, and soil microbial community structure was the new research leading edge.
