Abstract: In order to analyze the research dynamics, hotspots and trends of factors of influencing agricultural soil N₂O emissions systematically and comprehensively, R-bibliometrix tool was used to analyze the literature related to the topic from three aspects of highly cited papers, keywords and historical direct citations based on Web of Science Core Collection Database. The results showed that the factors influencing agricultural soil N₂O emissions were soil properties (soil type; texture; pH; temperature; moisture; bulk density; redox potential; oxygen; mineral nitrogen including nitrate and ammonium; organic carbon; enzymatic activities mainly including nitrate reductase and nitrite reductase, and soil microbial diversity), management practices (nutrient management including nitrogen fertilizer type; nitrogen fertilizer application rate; fertilization time and pattern; crop type; sowing time; tillage; irrigation; straw return or crop residue addition; biochar; nitrification inhibitor; land use change and so on), climatic conditions (snow; frost; precipitation; temperature; photosynthetically active radiation and so on), underground water level and ecosystem nitrogen saturation. On the macro scale, research hotspots mainly focused on the estimation of agricultural soil N₂O emissions inventory by using models from the global, national and regional scales, and the effective measures of mitigating agricultural soil N₂O emission based on the influence factors of agricultural soil N₂O emissions. On the medium and micro scales, research hotspots mainly focused on the response of agricultural soil N₂O emissions to influence factors (mainly single factor) in field or indoor experiments based on the analysis of soil physicochemical and microbial indicators. The historical trends in the research field of influence factors of agricultural soil N₂O emission were from soil properties to anthropogenic management. In this process, models were used to investigate the emission process, mechanisms and mitigation measures from the perspective of multi-factor and large-scale. Generally, nitrogen fertilizer managements including the application of nitrification inhibitors, coated fertilizers, biochar and straw were used as effective measures for mitigating agricultural soil N₂O emission according to the specific conditions. Our findings suggest that the further studies about agricultural soil N₂O emission should take multi-factors and multi-scales into account, in order to clarify the relative importance of the influencing factors and mechanisms, and should establish scientific and effective measures for mitigating agricultural soil N₂O emissions.
