The bibliometrical analysis of remote sensing research hotspots for the South China Sea and its U-boundary
Abstract: This paper renovated in taking bibliometrics to analyze journal articles with related themes published in and before 2019, to comprehensively evaluate the situation of ocean remote sensing application in South China Sea (SCS), especially in its U-boundary, we employed CNKI (China National Knowledge Infrastructure) and WOSCC (Web of Science Core Collection) as the representatives of journal article databases in Chinese and in foreign languages respectively. The classifying selection results are as followed: 10150 articles in Chinese and 10130 in foreign languages were published on natural science of SCS, 560 in Chinese and 1296 in foreign languages on remote sensing of SCS, and 309 in Chinese and 33 in foreign language on the U-boundary of SCS. The bibliometrical analysis shows that the country with the most articles in all kinds of languages was China (18253), where the top publishing institutions (such as No.1 South China Sea Institute of Oceanology, Chinese Academy of Sciences) and the journals (such as No.1 Journal of Tropical Oceanography) were primarily from; The annual article qualities on SCS natural science experienced 4 stages (slow start, slow growth, fast growth and fallback), SCS remote sensing experienced 2 stages (slow start and fast growth), while that on the U-boundary experienced 3 stages (slow start, fast growth and fallback); The research hotspots of SCS natural sciences were monsoon, gas hydrate and typhoon, while the research hotspots of SCS remote sensing were Sea Surface Temperature (SST), chlorophyll and typhoon and those of the U-boundary were SCS dispute and geologic feature. Our study finds that it was in 1974 that remote sensing data was first applied on the research of SCS typhoons, and it was in 2019 that remote sensing data was first used on ecological environment research of the U-boundary. It is of great significance to develop comprehensive scientific research on the U-boundary corridor in South China Sea by developing remote sensing technology.
