3S技术在地震研究领域应用的研究进展

随着3S(RS、GIS、GPS)技术的快速发展,其在地震领域上的应用已引起国内外研究机构和学者的广泛关注。以Web of Science核心数据集为文献源,检索2000-2019年3S技术应用于地震领域的文献,利用Citespace可视化分析软件进行文献分析,通过探究研究主题及研究热点的演变趋势,总结分析了当前研究前沿。研究结果表明,3S技术应用于地震领域涉及到了多个交叉学科及方向,体现出地震领域的研究具有广泛性和综合性的特点;通过聚类分析,发现可划分为8个知识群组,形成了以"地震案例"与"板块运动"为主的两条演化路径;关键词分析表明"合成孔径雷达应用"、"模型反演","滑动分布研究"成为近几年的研究热点,并趋向于多样化的趋势发展。

Application of 3S Technology in Seismic Research

With the rapid development of 3S(RS,GIS,GPS)technology,more and more scientists and research institutions in worldwide focused on the topic of its application in the field of earthquake.Based on the papers in database of Web of Science Core Collection we use data from articles about“Seismic application of 3S technology”during 2000 to 2019.we synthesize information visualization methods,bibliometric methods and data mining algorithms and visualizes the development process and structural relationship of research data using the information visualization analysis software,Citespace.The results indicated that the application of 3S technology in the field of earthquake involves many interdisciplinary subjects and directions,reflected that the research are comprehensive and extensive.Through cluster analysis,there are eight knowledge groups and formed two main evolution paths around“earthquake case”and“plate movement”.In recent years,The development of the research has a tendency of diversification and focused on“InSar”,“model inversion”and“sliding distribution”.
