基于CiteSpace的重金属时空污染热点及前沿可视化研究
|
摘要
为了解国内GIS技术支持下的重金属污染研究现状和未来发展路径,采用文献计量方法和信息可视化软件CiteSpace V,对CNKI数据库中1996—2018年GIS技术支持下的重金属污染领域的1 128篇文献进行了基础知识框架、研究热点、研究前沿分析,并绘制了网络知识图谱。结果表明,重金属污染相关主题研究热点和前沿大致分为3个阶段,即1996—2005年,研究热点和前沿为基于地统计学的重金属空间分布;2005—2010年,研究热点和前沿为基于GIS的重金属时空分布与空间变异;2010年至今,研究热点为沉积物重金属,前沿为重金属的风险评价与源解析。
In order to understand the research status and future development path of heavy metal pollution supported by domestic GIS technology, using the literature measurement method and information visualization software CiteSpace V, the basic knowledge framework, research hotspots and research frontiers were studied in the 1 128 papers in the field of heavy metal pollution supported by GIS technology in the CNKI database from 1996 to 2018, and the network knowledge map was drawn.The results show that the research hotspots and frontiers of heavy metal pollution are divided into three stages, namely, from1996 to 2005, research hotspots and frontiers are spatial distribution of heavy metals based on geostatistics; from 2005 to 2010, research hotspots and frontiers are spatial and temporal distributions and spatial variability of heavy metals based on GIS; and since 2010, the research focus has been on heavy metals in sediments, and the frontier is the risk assessment and source analysis of heavy metals.
