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.
Development process and prospect of sustainable development research supported by earth observation based on bibliometric analysis
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.
