摘　　要：疏浚底泥是具有环境风险的沉积物,产生于水体治理过程且产量巨大。本文利用Web of Science引文数据库,借助CiteSpace可视化分析工具,对1994~2020年该库收录的相关文献进行分析,了解其研究领域内的热点方向和前沿动态,以构建基于全球研究视野的疏浚底泥研究图谱。全球范围内的底泥研究整体呈上升趋势,不同合作子网络的作者研究侧重点不同。发文量靠前的机构主要集中在中国、美国以及部分欧洲国家。重金属、疏浚工程、修复和污染等是复现频次较高的关键词。底泥污染的背景研究、底泥中各种污染物的修复以及底泥的资源化利用是目前疏浚底泥的研究热点,且底泥资源化利用将是未来实现绿色发展的研究前沿。Dredged sediments are environmentally risky sediments which result from water remediation processes and are produced in huge quantities.This paper uses the Web of Science citation database and the CiteSpace visual analysis tool to analyze the relevant literatures included in the database from 1994 to 2020.This paper analyzes the hotspot directions and frontier trends in this research field,and a dredged sediments research map based on a global research perspective was constructed,showing an increasing trend with different research focuses in different cooperative sub-networks.The institutions with the highest number of publications are mainly from China,the United States and some European countries.Heavy metals,dredging engineering,remediation and pollution are keywords with a high repetition frequency.The background research of the sediment pollution,the remediation of various pollutants in sediment and the resource utilization of the sediment are the current research hotpots in the dredged sediment.And the resource utilization of sediment will be the research frontier for realizing a green development in the future.

关 键 词：疏浚底泥 可视化分析 合作网络 研究热点 资源化利用
