以 2010-2020 年间Web of Science(WoS)核心合集和中国知网(CNKI)数据库为数据源,运用CiteSpace软件对污泥土地利用研究发文量、研究力量和研究热点进行计量可视化分析,旨在探析当前国内外研究现状,探索前沿动态和未来发展趋势.结果表明,污泥土地利用研究总发文数量变化幅度较小,该领域研究热度处于平稳状态;在两大数据库中,美国和中国是该领域中合作研究多且影响力大的国家,最活跃的研究机构是中国科学院,作者及研究团队间的合作相对较少;国际上污泥土地利用研究趋于多元化发展,而我国在该领域的研究方向则比较单一,偏重于重金属研究.基于文献共现聚类和研究热点分析,提出污泥土地利用研究的未来展望:在多个层面开展合作研究,积极研发无害化污泥土地利用技术,全方面跟踪监测和评估污泥土地利用对陆地生态系统的影响,多部门联合制定污泥土地利用相关政策和技术规范.
Current status and future prospects of sludge land use based on CiteSpace visualization mapping analysis
Sludge land use is one of the most important ways in sludge disposal.Containing toxic and harmful substances,it has been seriously discussed by governments and researchers in the process of sludge land use.In order to understand the current research status,frontiers and future trends of sludge land use,we collected a total of 1961 published articles from Web of Science and CNKI databases(2010-2020),and then measured and visualized the volume of China's domestic and international publications,research forces and hotspots in this field using CiteSpace software.The results showed that:(1)Total number of published papers in sludge land use research did not change too much from 2010 to 2020.Research has been keeping attention in the field.(2)The world's most influential researches in this field came from the United States of America and China among countries,and the Chinese Academy of Sciences accounted for the highest number of published articles among institutes.However,there is relatively less cooperation cross authors and research teams.(3)The international research on the sludge land use tends to be diversified in the future,while current research topic in China is relatively sole,which only focusing on the heavy metal research.Based on the analysis of literature co-occurrence clustering and hotspot,we proposed several points about sludge land use should be given more attention in the future,such as collaborative research at multiple levels,study on harmless sludge land use technology,monitoring and evaluation the effects of sludge land use on terrestrial ecosystem,setting policies and technical specifications by multi-departments.
