Abstract

Total amount accounting of pollutants into river is the key link of total amount control system,under the condition that non-point source pollution has not been monitored effectively,according to the principle of pollutant input-output balance, MATLAB software is used to optimize the solution function, the Qing He river basin was taken as the demonstration area,the water quality monitoring data、 pollution source census data and monitoring data from 2009 to 2013 were used to build a binary statistical model for the total amount of pollutants discharged into the river. Nash efficiency coefficient (NSE) was used to verify the model coefficients, the statistical model is established and four model coefficients are proposed. The simulation results can accurately calculate the monthly amount of ammonia nitrogen into the river,the established statistical model has strong data assimilation ability, it can accurately calculate the annual amount of ammonia nitrogen into the river, the test results can meet the needs of practical research.
