基于文献计量学分析黑土土壤有机质研究现状及发展趋势

Research status and development trend of soil organic matter in black soil based on bibliometric analysis

黑土土壤是中国重要的耕地资源之一,有机质含量对土壤质量和农作物产量有重要影响。利用文献计量学分析方法,通过收集和分析发文量、期刊来源、作者、研究机构、关键词和摘要等信息,对我国黑土土壤有机质研究的现状和发展趋势进行了综述,揭示了该领域关注焦点和研究热点。结果表明:我国黑土土壤有机质相关研究整体呈上升趋势;科研机构和高校是主要的研究力量,中国科学院东北地理与农业生态研究所与东北农业大学在该黑土地相关研究中处于领先地位;通过关键词聚类分析和共现分析,该领域研究主要集中在土壤有机质含量、土壤模型和遥感技术、有机质分解与转化、有机质对土壤质地和养分的影响等方面。未来应加强多学科的交叉合作研究,重点关注黑土土壤有机质动态变化机制机理、多尺度、多时段的遥感监测技术等研究。

Black soil is one of the important cultivated land resources in China,and the content of organic matter has an important impact on soil quality and crop yield.This paper uses bibliometrics analysis method to summarize the current situation and development trend of black soil organic matter research in my country by collecting and analyzing the number of published papers,journal sources,authors,research institutions,keywords and abstracts,and reveals the concerns of this field.Focus and research hotspots.The results show that the research on black soil organic matter in my country is on the rise;scientific research institutions and universities are the main research forces,and the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences and Northeast Agricultural University are in the leading position in black soil related research;Class analysis and co-occurrence analysis.Research in this field mainly focuses on soil organic matter content,soil model and remote sensing technology,organic matter decomposition and transformation,and the impact of organic matter on soil texture and nutrients.In the future,multidisciplinary cross-cooperative research should be strengthened,focusing on topics such as the dynamic change mechanism of black soil organic matter,multi-scale,and multi-period remote sensing monitoring technology.
