基于文献计量的对地观测技术支撑 可持续发展研究进展与展望.

In the past few decades, earth observation has experienced rapid development, which provides necessary theoretical knowledge, research means and methods for global sustainable 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 development research based on earth observation from 1991 to 2021. This study analyzed the research progress based on the literature output trends, publishing regions and cooperation network, high-frequency terms and terms with the strongest citation bursts, and proposed future research 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 divided into germination stage, growth stage and rapid development stage. ②There is close international 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 developing countries have a dominant position in the number of publications, but their international influence still needs to be improved. ③At present, research focuses on the environmental protection 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 intelligence, 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 observation 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 observation 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 cooperation and take global action. These can help us to provide effective strategic and decision reference for the realization of the Sustainable Development Goals.
