Identification of critical non-point source areas of nitrogen in Changle River watershed

DENG Ouping1,2,SUN Siyang1,3,Lü Jun1,* 1.College of Environmental & Resource Sciences,Zhejiang University,Hangzhou 310029 2.College of Resource and Environment,Sichuan Agricultural University,Chendu 611130 3.National Institute of Measurement and Testing Technology,Chengdu 610021  
Based on the field monitoring,investigation,and analysis,a 3-year(2007—2009) dataset on water quality,hydrology,soil and weather condition,land use,and nitrogen sources was developed for the Changle River watershed,a typical agricultural watershed in eastern China.All types of spatial databases and attribute databases required for the ArcSWAT(Soil and Water Assessment Tool) model were established.The ArcSWAT model was efficiently calibrated and validated for modeling watershed runoff,sand and total nitrogen(TN) dynamic processes.Using the calibrated and validated ArcSWAT model,the critical periods and source areas for watershed nitrogen pollution were quantitatively identified.Results indicated that the established ArcSWAT model could be applied for practical watershed water quality management,as shown by the modeling efficiency coefficients ≥0.5,determination coefficients ≥0.6,and relative errors 20% of the three components.Rainy season(i.e.June—August) was the critical period for TN pollution,as the cumulative TN export loads to the river accounted for 50% of annual amount.Among seven towns within the watershed,Chongren Town,Lushan Town and Ganlin Town located in the southeast yielded the highest TN export rates to the river per area(i.e.,42.8~48.5 kg · hm-2 · a-1) and were the critical areas for TN pollution.For these critical areas,soil nitrogen pool,atmospheric deposition and chemical fertilizer application contributed to 23%,29% and 38% of total TN exported load to the river,respectively.Great attention should be paid onto these nitrogen sources for TN pollution.The quantified information on the critical period and source area will help local decision makers to control watershed nitrogen pollution in an effective and efficient manner.
