To understand the current situation of agricultural non-point source pollution research, this study analyzed 1000 representative papers (including core journal papers, master theses and doctoral dissertations) on agricultural non-point source pollution in CNKI from 2008 to 2019. On this foundation, the future development trend of agricultural non-point source pollution research in China was forecasted by obtaining the current research content and hot spots in this field. The research status and development trend in this field were analyzed by visual analysis method. The results show that the research field of agricultural non-point source pollution has developed. The total amount of articles has an upward trend; high-frequency vocabulary mainly includes chemical fertilizer, livestock manure and farmers. From the time line, the previous studies focus on the status of pollution, the pollution load of the target area, the surface and underground runoff, and the use of fertilizers. In the later period, the prevention and control of non-point source pollution in agriculture, the national control policy and pollution control technology are high-frequency words, indicating that more and more attention has been paid to the prevention and control of non-point source pollution. The results of this study could provide some reference data for the prevention and control of agricultural non-point source pollution and policy formulation in China.
