基于文献计量的堆肥研究现状与趋势研究

利用文献计量法和信息可视化软件VOSviewer对Web of Science文献检索中的SCI-EXPANDED数据库获得的检索结果分析当前堆肥研究的现状和发展趋势。美国、中国和西班牙三个国家发表的论文数量分别占论文总数量前三位。从研究内容上看,堆肥、降解、污泥、有机物、氮和重金属等关键词出现的频率较高。结果表明堆肥研究将侧重在堆肥的碳氮元素变化、堆肥对植物生长的影响、堆肥腐熟度和稳定度的判定、污泥堆肥重金属元素的生物有效性等方面。

Research Status and Development Trend of Composting Based on Bibliometrics

This study uses bibliometrics and information visualization software VOSviewer to analyze the search results ob-tained from SCI-EXPANDED database from Web of Science to learn research status and development trend of composting at present.The number of papers from United States,China and Spain respectively accounted for the top three of the total number of papers.From the perspective of specific research,keywords such as compost,degradation,sludge,organic matter,nitrogen and heavy metals appear more frequently.The study concluded that the future research would focus on the changes of carbon and nitro-gen in composting, the effect of compost on plant growth, the judgment of compost maturity and stability,and the bioavailability of heavy metal elements in sludge compost.
