Research on Nonpoint Source Pollution Assessment Method in Data Sparse Regions: A Case Study of Xichong River Basin, China

Table 5

The comparison of loads in TP and TN between the ECM and BTOPMC model (unit: ton).

PollutantsData sourceHongxi RiverLongtan River

TNECM530.31338.19
BTOPMC 362.58279.98
Difference167.7358.21

TPECM40.4924.59
BTOPMC 33.6217.08
Difference6.877.51

Note: the statistical results by ECM are expressed as the amount of pollutants which are input to the river in 2012. The results by BTOPMC are expressed as the yearly fluxes of pollutants in sections in 2012. The amount of difference between these two results reflects the environmental capacity and self-purification capacity of rivers.
