The formative process of non-point source pollution (NSP) is complicated, and can be hardly simulated with a traditional mathematical method or determined with overseas existing model parameters. This problem can be solved by calculation with the BP network. In the paper, the BP network is applied in simulation and calculation of the total N load in NSP of Heilongjiang. The application indicates that the BP network is feasible
