基于知识图谱的中国城市矿产研究进展

Evolution of urban mineral resources research based on knowledge maps

城市矿产是工业化和城市化的产物,具有重要生态价值和经济价值,对城市矿产进行科学、深入、全面的研究有助于其可持续开采和利用。本文基于文献挖掘视角,以1988—2018年间与城市矿产相关的4351篇中文研究文献为对象,运用科学计量学与文本挖掘相结合的方法,定量研究该领域历年来相关研究的动态发展状况,并对未来发展趋势展开分析。研究发现:(1)中国城市矿产研究正处于发展瓶颈期,存在5个主要研究团队,以理论研究为主,其中翟昕和周永生所在团队着手该领域的研究较早(2010—2014年),赵玉柱和李金惠所在团队在中间阶段较为突出(2015—2016年),王昶所在团队在近期较为突显(2017—2018年);(2)"矿产资源"(1995年)、"可持续发展"(2002年)、"矿业城市"(2004年)、"资源型城市"(2005年)、"循环经济"(2007年)等关键词在"城市矿产"(2010年)一词形成过程中扮演重要的更迭或者过渡角色,这与人们对城市矿产概念和认识的深化相关;(3)该领域在不同时间段的研究热点各异,政策导向性较为明显,与社会热点相结合是未来发展的趋势;(4)政策工具、技术进步与创新是该领域未来研究的重要关联主题。本文的研究能够帮助科研工作者和决策者快速了解和掌握城市矿产领域的研究状况和趋势方向,为推进城市矿产的深入研究和科学决策提供重要参考价值。

Urban mineral resources are an inevitable product of industrialization and urbanization process,which has significant ecological and economic values.Scientific and comprehensive research on urban mineral resources is conducive to their sustainable development and use.This study combined scientometrics with text mining methods,and took 4351 Chinese publications on urban mineral resources from 1988 to 2018 as the research object to quantitatively analyze the dynamic change of relevant research in this field over the period and future development.The results show that(1)The development of urban mineral resources research in China is in a bottleneck period and there are five main research teams in the field,mainly conducting theoretical research.Among these five teams,Zhai Xin and Zhou Yongsheng’s teams begin earlier in this field in 2010-2014,Zhao Yuzhu and Li Jinhui’s teams are more prominent in 2015-2016,and Wang Chang’s team becomes more prominent in 2017-2018.(2)"Mineral Resources"(1995),"Sustainable Development"(2002),"Mining Cities"(2004),"Resource-Based Cities"(2005)and"Recycling Economy"(2007)play an important role of transition in the formation of"urban mineral resources"(2010),which is related to the deepening of people’s understanding of urban mineral resources.(3)The research hotspots in this field are distinctive and clearly influenced by government policies in different time period,and incorporating social concerns is the future development trend.(4)Policy tools and technological advancement and innovation are the important topics for future research in this field.The analysis of change of urban mineral resources research based on literature mining can help researchers and decision makers to quickly understand and grasp the current status and trend of the research,and provide an important reference for the indepth research and decision-making of urban mineral resource development.
