我国矿区生态环境评价可视化研究分析

Visual Study and Analysis on Ecological Environment Evaluation of Mining Areas in China

矿山生态环境修复及其效果评估是生态文明建设的重要组成部分。为探究矿区生态环境评价领域研究热点并预测未来趋势,以CNKI为数据源,1992—2021年矿区生态环境评价相关文献为对象,采用文献计量软件CiteSpace进行科学知识图谱可视化分析。对期刊文献被引网络、合作机构及作者网络进行时空序列分析。结合被引分析与关键词分析,整理研究热点,总结发展脉络。近30年来,矿区生态环境评价领域可分为3个阶段:起步萌芽期(1992—2000年)、快速发展期(2001—2009年)、发展稳定期(2010年—)。对合作知识图谱分析得出,高产作者以白中科、徐友宁、陈勇、闫旭骞、汪云甲为代表。主要研究力量来自各大高等院校,发文量排名前三的院校机构为:中国地质大学、中国矿业大学、中南大学。通过梳理归纳,总结该领域研究热点主要集中在评价对象、评价方法、评价技术手段与评价指标体系4个方面。未来矿区环境评价发展依赖于研究机构、研究团队及校企之间深入合作,环境评价体系完善,地理信息、计算机、数学、生态学等多学科交叉融合研究。

Mine ecological environment restoration and its effect evaluation are important parts of the construction of ecological civilization.In order to explore the research hotspots in the field of ecological environment evaluation of mining areas and to predict the future trends,CNKI was used as the data source and the relevant literature of ecological environment evaluation of mining areas from 1992 to 2021 was taken as the object.Then,the bibliometric software CiteSpace was used for visual analysis of scientific knowledge graph.Spatio-temporal sequence analysis of journal literature citation networks,collaborating institutions and author networks was carried out.Combined with the analysis of citations and keywords,the research hotspots were sorted out and the development context was summarized.In the past three decades,the ecological environment evaluation can be divided into three stages,including the initial embryonic period(1992—2000),the rapid development period(2001—2009)and the development stabilization period(2010—).The analysis of the cooperative knowledge graph shows that the high-yield authors are represented by BAI Zhongke,XU Youning,CHEN Yong,YAN Xuqian,WANG Yunjia and so on.The main research strength comes from major colleges and universities,and the top three institutions in terms of article volume are:China University of Geosciences,China University of Mining and Technology,and Central South University.Through combing and summarizing,the research hotspots in this field are summarized and mainly focus on the following four aspects:evaluation objects,evaluation methods,evaluation means and evaluation index systems.The future development of ecological environment evaluation depends on three aspects,including the in-depth cooperation between research institutions,research teams,schools with enterprises,the improvement of the environment evaluation system,and the cross-integration of geographic information,computer,mathematics,ecology and other multidisciplinary research.
