| Abstract: | Ammonia nitrogen (NH4 -N) is one of the three main forms of total nitrogen (TN). Most studies have estimated the load of TN from nonpoint sources instead of one specific form. The relationship between land use and concentrations of NH4 -N in runoff was analyzed using the hydraulic analysis functions of a Geographic Information Systems (GIS), and the annual loads of NH4 -N in the Xitiao River catchment were estimated according to model results. The results suggested that the calculated annual loads of NH4 -N... |
