| 英文摘要 | Ammonia nitrogen (NH 4 + -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 NH 4 + -N in runoffwas analyzed using the hydraulic analysis functions of a Geographic Information Systems (GIS), and the annual loads of NH 4 + -N in the Xitiao River catchment were estimated according to model results. The results suggested that the calculated annual loads of NH 4 + -N agreed well with the observed ones, which was a good example demonstrating that it was possible to estimate the pollutant loads from nonpoint sources without enough monitoring data. Results also showed that the concentrations of NH 4 + -N in river waters of forest and arable land in the study area were 0.16 and 0.39 mg 4 + -N from 1995 to 2001 (except 1998 and 2000) varied between 2,098 and 7,992 tons |
