AB  - Nitrogen (N) loss by surface runoff inevitably results in severe N pollution and 
      eutrophication of aquatic ecosystems. In this study, surface runoff from 
      different land uses in the East Tiaoxi River watershed was collected, and the N 
      concentrations, sources and losses were measured using the dual isotope 
      (delta(15)N-NO(3)(-) and delta(18)O-NO(3)(-)), a Bayesian isotopic mixing (SIAR) model 
      and Soil Conservation Service Curve Number (SCS-CN) method. The results showed 
      that the N concentrations in surface runoff from agricultural lands were higher 
      than those from urban areas and forestlands, and nitrate (NO(3)(-)), particulate 
      nitrogen (PN) and dissolved organic nitrogen (DON) were the major forms of N in 
      surface runoff in the East Tiaoxi River watershed. The total loss rate of total 
      nitrogen (TN) from surface runoff in the East Tiaoxi River watershed was 
      5.38 kg.ha(-1).a(-1), with NO(3)(-)-N (46%) contributing the most to TN loss. The 
      TN, and NO(3)(-)-N loss rates in surface runoff from tea planting lands 
      (21.08 kg.ha(-1).a(-1), 11.98 kg.ha(-1).a(-1)) and croplands 
      (16.93 kg.ha(-1).a(-1), 10.96 kg.ha(-1).a(-1)) were high, those from vegetable 
      lands and urban areas were medium, and those from economic and natural 
      forestlands were low in the East Tiaoxi River watershed. The NO(3)(-)-N 
      contributions of chemical fertiliser (CF), soil N (SN), sewage/manure (SM), and 
      atmospheric deposition (AD) in surface runoff in the East Tiaoxi River watershed 
      were 124.32 x 10(3), 104.84 x 10(3), 82.25 x 10(3) and 58.69 x 10(3) kg.a(-1), 
      respectively. The N pollutant losses in surface runoff from agricultural lands 
      (croplands with rice growing, vegetable lands and tea planting lands) were 
      responsible for most of the N pollutants being transported into the East Tiaoxi 
      River systems.
