【摘要】 该文以中国知网学术期刊网络出版总库中1990-2017年收录的硕博论文和期刊论文为数据源,采用文献计量学方法对城市扬尘的相关文献进行统计分析及数据挖掘,通过共词来聚类分析国内关于城市扬尘研究领域的热点及现状。结果表明国内对于城市扬尘的研究整体呈现上升趋势,近几年呈逐渐成为环保领域的研究热点;从研究机构分析可知南开大学在该领域研究较多,且该方向的研究成果主要来自高等院校。对不同时期的研究主题通过共词聚类分析可知,在不同时期对于城市扬尘方向较为集中,现有的研究仍然偏重基础理论研究,主要以区域颗粒物来源解析、成分分析、形成机理研究等为主,而对于城市扬尘的治理和防治研究相对缺乏,故在今后的研究中可向城市扬尘治理措施、措施应用研究、措施效果评估等方向拓展。更多还原

【Abstract】 The journal papers from 1990 to 2017 in the China National Knowledge Infrastructure(CNKI) are used as data sources in this paper, literature metrology is used to conduct statistical analysis and data mining of relevant literature on urban dust, and co-word cluster analysis is used to analyzes the hot spots and current status of urban dust research in China. The results show that the research onurban dust is on the rise in China, which become a hot topic recently. It can be observed in the analysis of research institutions that Nankai university has a lot of research in this field, and colleges and universities have a strong strength in the field of urban dust research. By analyzing the subject of research in different periods, it can be seen that the direction of urban dust is concentrated in different periods. The study of urban dust gradually changed from the basic theoretical study to the study of governance measures. At present, the research is mainly focused on the analysis of the source ofparticulate matter in the dust. In the subsequent research, systematic research on urban dust governance measures, evaluation of the effect of measures and other directions can be further expanded.更多还原
