基于文献计量学的农业生态荟萃分析的研究进展

Agroecology Meta-analysis Based on Bibliometrics:A Review

为了解荟萃分析在农业生态学科研中的发展和应用,提供相关研究参考,以“meta”作为关键词获取有效文献718篇,利用CiteSpace可视化软件和Web of Science(WOS)文献分析工具进行量化。结果表明,农业生态荟萃分析的国际发文总量呈显著增长;美国加州大学戴维斯分校、中国农业大学、中国科学院、中国农业科学院、荷兰瓦赫宁根大学在农业生态荟萃分析领域有较高的国际影响力。荟萃分析在农业生态的研究主题多样化,农田管理措施、土地利用方式变化、气候因子变化对生物多样性、温室气体等的生态环境效应评估和碳氮养分循环的动力学分析,以及不同生态系统之间的变化、互作差异比较等是现阶段的主要应用领域。荟萃分析作为农业生态学研究的重要工具,为大尺度综合性研究提供了验证假说和发展新理论的新途径,但目前简单荟萃研究仍难以完全满足实际工作需求,基于大数据融合、机器学习模型算法和专家知识评估等的综合荟萃分析将是未来研究的重点。

To understand the development and application of meta-analysis in agroecology research and provide reference for relevant research,718 valid literature was obtained with‘meta’as the keyword,and quantified by CiteSpace visualization software and Web of Science(WOS)literature analysis tool.The results show that the total number of international publications in agro-ecological meta-analysis has increased significantly.University of California,Davis(UC Davis),China Agricultural University,Chinese Academy of Sciences,Chinese Academy of Agricultural Sciences and Wageningen University have high international influence in the field of agro-ecological meta-analysis.The research topics of agroecology meta-analysis are diverse.The assessment of ecological and environmental effects of farmland management measures,land use change,climate change on biodiversity and greenhouse gases,the dynamics of carbon and nitrogen nutrient cycling,and the changes and interaction difference of different ecosystems are the main application fields at the present stage.As an important tool for agro-ecological research,meta-analysis provides a new way to verify hypotheses and develop new theories for large-scale comprehensive research,but it is still difficult to fully meet the needs of practical work by simple meta-analysis.A comprehensive meta-analysis based on big data fusion,machine learning model algorithms and expert knowledge assessment will be the focus of future research.
