摘要
为了形象客观地了解国内外2016—2020年环境土壤学相关研究的发展特点,本文收集了发表在Web of Science和中国知网上土壤环境领域的相关文章,利用Web of Science自带分析工具和文献计量学软件CiteSpace,分析了该领域的研究现状、发展方向和热点。结果显示,2016—2020年间土壤环境领域研究成果丰硕,发展平稳,中美两国发文占比超过国际领域发文的50%。国际环境科学类刊物Science of the Total Environment、Environmental Science and Pollution Research和Chemosphere发文量最高,土壤科学类期刊Geoderma、Catena、Plant and Soil和Soil Biology Biochemistry也在发文前十行列。从国际上看,土壤环境领域共有微生物群落、有机碳、生物炭改良、N2O排放、重金属、土壤侵蚀、机器学习、保护性农业8个重要研究方向及相关热点;国内研究紧跟国际发展,侧重于土壤有机质、养分和微生物等研究热点,也围绕土壤水分、生物炭、土壤侵蚀和作物产量等热点开展了大量研究。
To comprehensively understand the development characteristics of environmental soil science between 2016 and 2020,the related articles published in Web of Science and China National Knowledge Infrastructure were collected.The research status,development trend and hotspots were analyzed based on analysis tools from Web of Science and bibliometric software CiteSpace.The results indicated that the field of environmental soil science has fruitful achievements and has developed steadily during the study period.China and the United States accounted for more than 50%of international publications.Environmental science journals including,Science of the Total Environment,Environmental Science and Pollution Research and Chemosphere had the most of publications,and soil science journals including,Geoderma,Catena,Plant and Soil and Soil Biology Biochemistry were in the top ten ranks as well.There were 8 important research trends and related hotspots in the field of environmental soil science overseas:microbial community,organic carbon,biochar amendment,N2O emissions,heavy metals,soil erosion,machine learning,and conservation agriculture.The domestic research closely followed international development and focuses on the hotspots including,soil organic matter,nutrients and microorganisms.Lots of efforts had also been paid on soil moisture,biochar,soil erosion and crop yield.
