| Abstract: |
| Soil salinization is one of the important issues threatening the sustainable development of irrigated agriculture in arid and semi-arid areas worldwide. Remote sensing technology can qualitatively and quantitatively monitor and assess soil salinization on a large scale, and provide support for soil salinization prevention and management. This article used bibliometric methods to quantitatively analyze the publication characteristics, research hotspots and evolution trends of the relevant papers in the field of soil salinization remote sensing monitoring included in the Web of Science core collection and the China National Knowledge Infrastructure database from 2000 to 2022, and visualized with the help of CiteSpace software. The results showed that: (1) Research on soil salinization monitoring based on remote sensing at home and abroad was generally on the rise. China, the United States and Germany were the most active countries in remote sensing research on soil salinization, and the Chinese Academy of Sciences was the most active researcher. The top three journals with the most published articles were "Remote Sensing", "Geoderma" and "International Journal of Remote Sensing"; (2) The field of soil salinization remote sensing monitoring had extensive intersection with other research fields, involving collaboration in multiple fields such as environmental science, remote sensing, water resources, electronic and electrical engineering, and the trend of cross-integration was significant. (3) Machine learning, climate change, and big data remote sensing platforms were hot areas of remote sensing research on soil salinization, and the impact of soil salinization on vegetation growth and the interactive effect of soil water and salt would also become an important research content of soil salinization remote sensing in the future. The results of this study demonstrate the development process and research hotspots of soil salinization remote sensing in the past 20 years, and provide a reference for related research to explore new research directions. |
