Heading towards carbon neutrality: How marine carbon sinks become an important handle for promoting marine ecological civilization construction?Literature review and research prospect based on the CiteSpace

Abstract

Abstract As an efficient long-term carbon sink, the mechanism of marine carbon sink, carbon sink effect, carbon sink technology, carbon sink accounting and carbon sink trading market construction are becoming new topics that need to be explored in various disciplines. Based on the research literature related to marine blue carbon sink in the core databases of China National Knowledge Internet (CNKI) and Web of Science (WOS), we use bibliometric tools to quantitatively compare and analyze the main characteristics of domestic and foreign marine blue carbon sink research such as publication volume, time, journals, authors and institutions; explore the research hotspots, stage frontier areas and theme evolution trends through keyword clustering, emergent and co-occurring knowledge maps. Finally, the key research directions of marine carbon sinks are prospected, we should take multidisciplinary interdisciplinary research as the leader to promote the unified carbon sink market research of land and sea integration; take comprehensive ecological compensation mechanism of marine carbon sink protection, marine carbon sink related theory and technological innovation research as the guide to continue to explore the application mode of marine carbon sinks In order to explore the blue carbon cooperation mechanism of the countries along the Maritime Silk Road. In order to sort out the current situation of marine carbon sink research at home and abroad, promote the research in this field to a deeper level of scientific and rational development, and provide reference and reference for subsequent scholars to carry out related research.
