| Abstract: |
| 【Purpose】 It is of great significance to make deep understanding of agricultural remote sensing research in South China，and to clarify the current research status，hotspots and cutting-edge issues in the field of agricultural remote sensing，so as to promote the development of agricultural remote sensing research in South China.【Method】 In this paper，based on the knowledge association method and bibliometric method，Web of Science core citation database was used as the data source for subject search. This method searched and analyzed metadata related to agricultural remote sensing research in South China，including publication trends，keyword co-occurrence，research fields，and technological hotspots.【Result】 There were 4 main characteristics of agricultural remote sensing research in South China from 2003 to 2023. Firstly，agricultural remote sensing research in South China had gone through three stages of starting（before 2010），fluctuating development（2011-2015）and accelerated development（after 2016），with increasing research fever. Secondly，the researches emphasized applied approach，focusing on crop growth and production factors such as soil，climate，pests and diseases. Thirdly，the researches focused on the regional characteristics of South China and the industrial problems of tropical and subtropical crops，such as natural rubber，bananas and sugarcane. Lastly，the researches emphasized technological innovation，and had innovated and developed lots of technical means for acquiring and analyzing agricultural remote sensing data.【Conclusion】 Facing the needs of agricultural science and technology innovation and sustainable development of agriculture in South China，the following recommendations were put forward：focusing on remote sensing survey and monitoring of agricultural resources in tropical subtropical areas，expanding the application of remote sensing by unmanned aerial vehicles for precision agriculture in the field of agriculture，fully exploiting and giving full play to the advantages of multimodal and multi-scalar data，and expanding the innovation and application of new technologies，such as artificial intelligence and big data. |
