Abstract: Based on the 2958 literatures in the core data of Web of Science and 2036 literatures in CNKI, carbon-related scientific studies in facility cultivation from 1978-2022 were reviewed using knowledge mapping and bibliometric methods. The results showed that researches in facility cultivation carbon had underwent four development stages, including 1978-1990, 1991-2002, 2003-2017 and 2018 to now. Five research fields had been formed: gas fertilizer and agronomic effect, soil environment and soil improvement of facility cultivation, environmental regulation of facility cultivation, greenhouse gas emission of facility cultivation, and sustainable development of facility cultivation, including 14 major research directions. Since 2002, studies on the impact of cultivation and management measures on greenhouse environment and studies on greenhouse gas emissions from facility cultivation and energy use have become the main research focus. Carbon emission characteristics, influencing factors and greenhouse gas emission reduction of facility cultivation will be the focus of future research on carbon of facility cultivation.
