The results showed that the TP non-point source pollution in Nanyi Lake was affected by the pollution source, the filtration rate of pollution load, and the mass concentration of potential TP runoff. The InVEST model has good applicability in areas where agricultural TP is the main source of pollution. This study shows that the InVEST model combined with the source list method provides a more effective method for identifying the key source areas of TP non-point source pollution in the river basin, and formulates corresponding measures according to their pollution characteristics, so as to provide a reference for the control of non-point source pollution in the basin.Read More
