Research Progress and Trend Analysis of Soil Inorganic Carbon Sink Based on Citespace

Abstract

To comprehensively understand the research status and development trend of soil inorganic carbon development, this study comprised 441 inorganic carbon pool papers from 1991-2022 in the Web of Science database based on CiteSpace software, and conducted Visualization analysis to explore the research hotspots, research status and development trend in this field. The results show that number of publications has increased year by year, and the clustering results show that the research topics mainly involve terrestrial biosphere, coastal forest ecosystem, forest soil, changed temperature hutrient. The hotspots of research include the blue carbon, soil carbon sequestration and dissolution processes of inorganic carbon. In addition, development trend include the effects of land use change, temperature, organic matter and other changes. soil inorganic carbon sinks, carbon dioxide uptake and the application of isotope technology are the ongoing concerns in this field, which will be the hotspot of soil inorganic carbon sink research in the future period.
