Study on Total Amount Accounting of Pollutants Entering Qinghe River Basin

The calculation of the total amount pollutants entering river is key to control system. Since non-point source pollution has not been monitored normally and effectively, based on principle balance input output pollutants, 2009-2013 Qinghe water quality monitoring data, survey data were used establish a binary statistics model. MATLAB software solve results show that model strong assimilation ability, can accurately calculate monthly COD inflow into river, divide point load, meet needs actual research.
