基于文献计量学的2001—2020堆肥臭气研究进展

堆肥是有机固废资源化利用的重要方式，而堆肥过程中产生的组分复杂的恶臭气体，限制了该技术的发展与推广应用。为了解堆肥臭气控制领域的研究趋势与重点，通过CiteSpace软件对CNKI和Web of ScienceTM核心合集数据库中2001—2020年共20年关于堆肥臭气研究的文献进行可视化分析。结果表明:近20年以来，堆肥臭气控制领域的发文量呈增长势态。核心研究团队为中国农业大学李国学团队。研究热点主要关注畜禽粪便、污泥、厨余等富含蛋白质或碳水化合物等易产生臭气的堆肥物料，氨气和挥发性有机物等臭气种类，添加外源调理剂、生物作用等除臭手段。食物垃圾堆肥产生的臭气治理，微生物作用下的臭气减排作用机理，以及臭气、重金属与抗生素抗性基因等多种性质污染物间的协同控制可作为未来的研究前沿。综上，堆肥臭气研究领域正处于活跃的发展状态，未来的研究视角也将更为多样化。

RESEARCH ADVANCE ON COMPOST ODOR IN 2001-2020 BASED ON BIBLIOMETRICS

Composting is an important way of resource utilization of organic solid waste. The development and application of composting are limited by the odor produced in the composting process. To understand the research trend and focus in the field of compost odor control, the literature on compost odor research in CNKI and Web of ScienceTM core collection database in 2001-2020, was visually analyzed by CiteSpace software. The results showed that the number of documents issued in the field of compost odor control keep increasing in recent 20 years. The core research team is Li Guoxue from China Agricultural University. Research hotspots mainly focus on composting materials rich in protein or carbohydrate and easy to produce odor, such as livestock manure, sludge and kitchen waste, odor components such as ammonia and volatile organic compounds, and deodorization means such as adding external regulators and biological effects. The treatment of odor produced by food waste composting, the mechanism of odor emission reduction under the action of microorganisms, and the collaborative control of odor, heavy metals, and antibiotic resistance genes should be research frontier in the future. In conclusion, the field of compost odor research is in an active development state, and the perspectives of future research will be more diverse.
