基于文献计量的校园垃圾分类回收研究现状与态势

Research Status and Advances of Campus Waste Classification and Recycling Based on Bibliometrics

为探究校园垃圾分类回收的研究现状、研究热点和前沿动态,以Web of Science核心合集数据库中1990-2023年收录的文献与其引文数据为基础,进行了包括发文情况、研究力量分布、关键词共现与时区分布、文献共被引与聚类分析,以及关键词突现分析在内的文献计量和知识图谱分析。结果显示:该领域发文量逐年增加,2010-2017年增加明显,主要集中于环境科学和教育领域;发展中国家和发达国家整体发文量相当,但发达国家的研究水平相对较高;多数研究机构的发文量较少,合作关系较弱;研究热点由早期的固体废物管理、环境教育、态度、行为和循环经济逐渐丰富至多个主题,包括电子废物、塑料废物、餐厨垃圾、零废物、计划行为理论及其拓展、分类意愿、可持续性、环境知识和环境绩效等。环境知识、环境可持续性和减量化、循环经济可作为未来的研究前沿,并应重点关注校园垃圾的特征成分研究,垃圾分类行为、意愿和影响因素研究以及绿色校园和可持续校园建设等方面。

To investigate the current status,hotspots,and frontier trends in the research on campus waste classification and recycling,based on the literature collected in the core collection of the Web of Science(WoS)database from 1990 to 2023 and their references,bibliometric analysis and knowledge mapping were conducted,which included the state of publications,the distribution of research power,keywords co-occurrence and time-zone distribution,literature co citation and cluster analysis,and burst analysis of keywords.The results showed that the number of articles in this field keep increasing annually,with a significant growth from 2010 to 2017,and the disciplines mainly focused on environmental science and education.The overall number of publications issued by developing countries and developed countries was comparable,but the research level of developed countries was relatively higher.Most research institutions had a small number of publications and a weak cooperative relationship.The main research hotspots had gradually enriched from early stages of solid waste,environmental education,attitude,behavior,and circular economy to multiple themes,including electronic waste,plastic waste,food waste,zero waste,planned behavior and extended theory,willingness,sustainability,environmental knowledge,and environmental performance.Environmental knowledge,environmental sustainability and reduction,and circular economy could be the research frontiers in the future,with a focus on the study of the characteristic components of campus waste,behavior,willingness,and influencing factors of waste sorting,as well as the establishment of green campus and sustainable campus.
