Abstract：With the increasing intensification of agricultural production, agricultural non-point source pollution has become one of the main sources of water eutrophication, and the issue of total phosphorus exceeding standards is particularly prominent, posing a serious threat to the safety of aquatic ecosystems. Currently, most research focuses on phosphorus control in industrial point sources or urban domestic sewage, and there has been no systematic exploration of the full-process mechanism of phosphorus migration and transformation in agricultural non-point sources, as well as corresponding efficient interception technologies. This paper mainly studies the mechanism of total phosphorus exceeding standards in agricultural non-point source pollution. After completing field monitoring and simulation experiments, it analyzes the transformation and release patterns of phosphorus forms during soil phosphorus accumulation, rainfall runoff scouring, and ditch transport processes, and clarifies the dominant contributions of dissolved phosphorus and particulate phosphorus under different hydrological conditions.
