为探讨近 30年城市生态遥感研究的发展趋势及热点,基于文献计量法,以Web of Science(WoS)数据库中的SCI及SSCI学术期刊和CNKI数据库中的学术期刊为数据源,运用文献分析软件CiteSpace绘制城市生态遥感领域知识图谱,对1991~2021年该领域发表的论文进行分析.结果表明:①就发文数量来看,城市生态遥感的研究经历了"萌芽阶段"、"累积阶段"和"快速增长阶段",呈现出良好的发展态势,发文量的质心在世界范围内也表现出从东部向西部然后又回归东部的迁移趋势;②就研究机构来看,在WoS与CNKI数据库中发文量最多的研究机构分别是中国科学院地理科学与资源研究所和北京师范大学;③就发文期刊来看,在WoS与CNKI数据库中发文量最多的期刊分别是Remote Sensing与《生态学报》;④就核心作者来看,中国科学院周伟奇与福州大学徐涵秋分别是WoS和CNKI数据库中发文量最多的作者;⑤通过对关键词的统计,"生态环境"、"土地利用"、"景观格局"为近年来城市生态遥感领域的研究热点.总体来看,城市生态遥感在环境科学、自然地理学、测绘学等学科占有越来越大的比重,应用生态遥感模型来定量评估生态环境质量成为该领域的重要趋势,城市生态遥感研究对遥感影像的分辨率要求越来越高,今后高空间和高光谱分辨率遥感影像将成为该领域的热门数据源,多源遥感数据协同反演城市生态也将成为该领域的发展趋势.
Visualization Analysis of the Development and Hot Spots of Urban Ecological Remote Sensing Research
Taking the SCI and SSCI papers in the Web of Science(WoS)and the journal papers in the CNKI as the data source,we used bibliometrics and the literature analysis software CiteSpace to explore the development and hot spots of urban ecological remote sensing in the past three decades and drew the knowledge map of the field from 1991 to 2021.The results show that:(1)in terms of the number of publications,the research on ur-ban ecological remote sensing has gone through three development stages,i.e.,budding stage,accumulation stage,and rapid growth stage;globally,the center of centroid of the number of published papers shows a trend of migration from the east to the west and then back to the east;(2)in the light of research institutions,Insti-tute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences and Beijing Nor-mal University have published most papers in this field in WoS and CNKI;(3)in terms of journals,Remote Sensing and Acta Ecologica Sinica have published most papers in this field in WoS and CNKI,respectively;(4)in terms of core authors,Weiqi Zhou in Chinese Academy of Sciences and Hanqiu Xu in Fuzhou University(China)published the most papers in WoS and CNKI,respectively;and(5)statistics of keywords shows that the keywords of ecological environment,land use,and landscape pattern were the hot spots of urban ecological remote sensing research in recent years.In general,urban ecological remote sensing was playing an increasingly important role in the disciplines of environmental science,physical geography,and geomatics.The application of remote sensing ecological models to quantitatively assess ecological environment quality has become an im-portant trend in this field.Also,urban ecological remote sensing research requires higher and higher spatial reso-lution of remote sensing images.Collaborative inversion of urban ecological quality with various remote sensing images will also be a development trend in this field.
