摘要
对地观测技术近年来快速发展,逐渐成为全球可持续发展研究的必要手段和方法.基于Web of Science核心合集数据库和CiteSpace软件,围绕"对地观测技术与可持续发展"领域论文进行文献计量分析,探讨了 1991-2021年相关研究的发展阶段、发文地区与合作网络、研究热点,并提出未来研究中有待加强的方向.研究结果表明:①1991-2021年间,"对地观测技术与可持续发展"领域的发文量呈上升趋势,可分为萌芽阶段、增长阶段和快速发展阶段;②"对地观测技术与可持续发展"研究的国际合作较为密切,其中,以美国、德国为代表的国家在发文数量和影响力上均处于领先地位,中国等发展中国家发文量占优势地位,但国际影响力仍有待提高;③"对地观测技术与可持续发展"的当前研究热点主要集中在对地观测技术支撑土地利用/土地覆被变化、气候变化、自然资源、水资源等环境保护相关内容,研究领域在技术方法上不断融合人工智能、数理统计等新兴手段.在未来的研究中,应持续加强对地观测技术的支撑作用,推动开展全球行动,规范数据共享机制等,以期为可持续发展目标的实现提供有效的决策参考.
Abstract
In the past few decades,earth observation has experienced rapid development,which provides necessary theoretical knowledge,research means and methods for global sustain-able development.By searching the Web of Science core collection database and using CiteSpace,a knowledge map tool,this study conducted a bibliometric analysis of sustainable de-velopment research based on earth observation from 1991 to 2021.This study analyzed the re-search progress based on the literature output trends,publishing regions and cooperation net-work,high-frequency terms and terms with the strongest citation bursts,and proposed future re-search directions.The results show that:①The number of articles published in the field of"earth observation technology and sustainable development"is generally on the rise,which can be di-vided into germination stage,growth stage and rapid development stage.②There is close interna-tional cooperation in the study of earth observation technology and sustainable development,among which,United States and Germany are in a leading position in terms of the number and influence of published paper.These countries are rich in scientific research.China and other de-veloping countries have a dominant position in the number of publications,but their international influence still needs to be improved.③ At present,research focuses on the environmental protec-tion related contents such as land use/land cover change,climate change,natural resources and water resources.In recent years,the research field has been constantly integrating artificial intel-ligence,mathematical statistics and other emerging methods,and the research content tends to be diversified.In the future research,it is necessary to fully achieve the supporting role of earth ob-servation technology and contribute to the achievement of the Sustainable Development Goals through a Decade of Action,and to deepen the study of earth observation data and facilitate data sharing in order to open up a new path for wide application.The combination of earth observa-tion data with traditional statistical data should be strengthened to achieve the fully functioning of the potential of earth observation in SDGs monitoring.We can focus on international coopera-tion and take global action.These can help us to provide effective strategic and decision refer-ence for the realization of the Sustainable Development Goals.
