Reducing carbon emission of rice field is an important research area for achieving carbon neutrality in agriculture. Comprehensively reviewing the history and frontier of this field could provide guideline for related research in the future. In this paper，based on a detailed analysis of literature related to carbon footprint research of rice field over the past 30 years(1990-2023)and using bibliometric methods，we explored the research process，focus themes，and development trends in this field. The results indicated that carbon footprint in rice fields had received widespread attention from scientists in the area. The number of literatures grew rapidly since 2009，and the contribution rate of published literature in the past ten years had reached 89.2%. A clear core research forces had been observed in the area. China，the United States，and India were the main countries for publishing literatures，which accounting for 75.9% of the total world publications. Ranking of the numbers of publication showed that six of the top ten research institutions were from China，and the Chinese Academy of Sciences ranked first. The analysis of
