城市雨污分流领域基于图谱可视化分析研究

Study on Visualization Analysis Based on Atlas in Urban Rain-Pollution Diversion

摘要: 为了分析当今城市雨污分流领域的发展趋势及目前研究热点问题，以“城市雨污分流”为主题词，通过CiteSpaceV分析软件对2004~2021年CNKI中国知网搜集到的608条文献数据进行可视化分析。研究结果表明：1) 目前国内关于城市雨污分流的研究方向相较于较早年份有较大进展，在发文量数量方面出现增长。2) 以宁建新，朱小娟，王增长，张弛，顾巍钟，崔旭等为中心发表了大量的学科文献。除此之外，大部分作者都是发文量仅在1~2次，说明研究城市雨污分流领域的作者众多，但就研究作者和机构之间联系密度还不够。3) 通过关键词共现图谱，结合词频，中心度，聚类等分析，“雨污分流”、“排水管网”、“排水系统”、“黑臭水体”、“合流制”等为近几年的研究热点；就此观察可以得出目前前沿的关于土石坝渗流的领域是关于“排水系统”方向的学习。本文研究结果可以为读者清晰梳理城市雨污分流研究近年来的研究成果及研究热点，并追溯城市雨污分流演化进程，从而为相关学者追踪该领域近期热点及未来发展趋势提供参考。

Abstract: In order to analyze the development trend and current research status of urban rain-pollution diversion, this paper uses “urban rain-pollution diversion” as the main topic and uses CiteSpaceV analysis software to carry out visual analysis of 608 literature data collected by CNKI from 2004 to 2021. The results show that: 1) At present, the domestic research on the urban rain-pollution diversion has made great progress compared with the earlier years, and the number of papers published has increased. 2) A large number of academic papers have been published with Ning Jianxin, Zhu Xiaojuan, Wang Zeng, Zhang Chi, Gu Weizhong and Cui Xu as the centers, in addition, most of the authors only publish 1~2 times, which shows that there are many authors in the field of urban rain-pollution diversion, but the density of relationship between authors and institutions is not enough. 3) Through the co-occurrence of keywords, combining the analysis of word frequency, center degree and cluster, “Rain-pollution diversion”, “Drainage pipe network”, “Drainage system”, “Black and odorous water body”, “Confluence system” and so on are the research hotspots in recent years; From this observation, it can be concluded that the current frontier field of earth-rock Dam seepage is about the study of “Drainage system” direction. The results of this study can provide readers with a clear overview of the research achievements and research hotspots in recent years, and trace the evolution process of urban rain-pollution diversion, thus for the relevant scholars to track the hot spots in the field in the near future and provide reference for the development trend.
