Abstract:Carbon emissions from agricultural sectors account for a third of all human-made carbon emissions. If no effective measures are taken, then the amount of agricultural emissions would increase steadily and dramatically. Figuring out the evolution of research on agricultural emissions is the prerequisite and foundation for exploring future research directions and guiding agricultural carbon reduction. Based on the databases, SCI-EXPANDED and SSCI, in Web of Science, this paper conducted the cluster analysis of co-citation, the analysis of pivotai-point articles and the burst analysis of keywords, adopting CiteSpace Ш. The results show that: (1) the number of articles about agricultural emissions raised annually; studies on agricultural emissions stand at the crossroads between ecology-environment science and the agricultural science. (2) Major research fronts include research on “the carbon emission and carbon sequestration of farmland/soil”, “non-co2 greenhouse gas producted by agricultural activities”, “the carbon footprint of agri-products” and “the carbon emission and carbon sequestration of land use change”. (3) the evolution process of research within this realm turned out to be clear, which stepped from field experiment or scenario analysis to present knowledge analysis or meta analysis, and then to analysis adopting process-based model (such as DeNitrification-DeComposition, DNDC). (4) the carbon footprint of agri-products adopting life cycle analysis, the food security problem under climate change situation, and the application of biochar have become the strongest citation bursts in the recent two years, which should be given more attention by future academic research.
