堆肥过程中氨气挥发和氮素损失等严重威胁环境质量、影响堆肥成品质量,是制约堆肥工艺发展的重要因素.利用Web of Science(WOS)核心合集英文数据库和CNKI数据库,通过对 1993-2022 年间在堆肥领域对氮排放和转化的相关文献进行计量分析并统计归类,了解近 30 年国内外堆肥领域有关氮排放和转化研究的趋向及特点,为今后相关研究提供思路.研究发现,我国是该领域发文量最高的国家,有较好的研究基础和研究成果,但存在国内作者之间研究合作团体不多、研究机构之间联系薄弱、核心研究机构之间缺乏交流合作的问题;该领域目前处于研究热门期,近十年发文量和引文量都大幅提升;该领域今后的发展预计会聚焦于微生物群落结构解析、由微生物驱动的硝化作用和反硝化作用过程、堆肥重金属富集以及堆肥成熟度等方面.
Analysis of Research on Nitrogen Emissions and Conversion from Composting in Past 30 Years Based on Bibliometrics
Ammonia volatilization and nitrogen loss during composting process seriously threaten the environmental quality and affect the quality of composting products,which are the crucial factors restricting the development of composting technology.Based on the Web of Science(WOS)core collection English database and CNKI database,the literatures on nitrogen emission and conversion during composting published from 1993 to 2022 were quantitatively analyzed and statistically classified to understand the trend and characteristics of the research on nitrogen emission and conversion during composting at home and abroad in the past 30 years,which could provide ideas for future research.It was found that China published the largest number of documents in this field,indicating that China has accumulated a solid research foundation and obtained great research achievements.However,there are problems with limited research cooperation groups among domestic authors,weak connections between research institutions,and a lack of communication and cooperation among core research institutions.Currently,the field is in a hot research period with a significant increase in the number of publications and citations in the last decade,and the future developments in this field are expected to focus on microbial community structure analysis,nitrification and denitrification processes driven by microbes,heavy metal enrichment in compost,and compost maturity.
