摘要：通过运用文献计量学方法和知识图谱可视化技术,对1991~2020年的WOS核心数据库中检索到的34 212条文献进行分析,以揭示学者们对城市生活垃圾研究的主题演化和热点趋势,为后续研究提供参考。通过聚类分析将研究主题划分为垃圾分类与回收、垃圾生态影响与评价、垃圾处理方式与技术、垃圾管理与公众行为四大类。全球学者对这些主题的关注点,在2000年前后出现变化,前期研究集中在垃圾焚烧以及过程中产生的空气污染,后期更加关注厨余垃圾、公众行为以及循环经济等相关问题。通过关键词爆发度指数(burst detection)分析发现,未来学者们应该关注循环经济大背景下的厨余垃圾、塑料垃圾的可持续利用问题,关注生物炭、水炭、纳米粒子等技术方面的革新进展,在管理方面,加强多主体的协作,包括企业资源回收技术、政府公共管理干预和居民参与度等,气候变化背景下的城市生活垃圾引起的温室效应及应对策略仍然存在巨大研究潜力。
In this study,34212 literatures retrieved from the WOS core database from 1991 to 2020 were analyzed by using bibliometrics methods and knowledge map visualization techniques to reveal the topic evolution and hot trends of scholars'research on municipal solid waste and provide reference for subsequent research.Through cluster analysis,the research topics are divided into four categories:waste classification and recycling,waste ecological impact and evaluation,waste treatment methods and technologies,waste management and public behavior.The focus of global scholars on these topics changed around 2000.Previous studies focused on waste incineration and air pollution generated during the process,and in the later stage,more attention were paid to kitchen waste,public behavior and circular economy.Through the analysis of keyword burst detection index,it is found that in the future,scholars should pay attention to the sustainable utilization of kitchen waste and plastic waste under the background of circular economy,and pay attention to the innovation progress of biochar,hydrochar,nanoparticles and other technologies.In terms of management,multi-agent collaboration should be strengthened,including enterprise resource recovery technology,government public management intervention and residents'participation.There is still great research potential in the greenhouse effect and coping strategies caused by urban domestic waste under the background of climate change.
