摘    要:以三峡库区大宁河流域为研究区域,应用SWAT模型进行了流域农业非点源污染负荷的模拟计算。利用巫溪水文站2000-2004年的实测日径流和泥沙数据进行了模型的率定与验证。验证结果表明,SWAT模型适用于大宁河流域。利用验证后的模型分析了大宁河流域2003年的非点源污染空间分布特征,结果发现,大宁河流域西部地区是土壤侵蚀发生相对严重的地区,有机氮产小的地区和高泥沙量产出的地区大致相同。总体上,大宁河流域非点源污染的产生量西部高于东部,南部高于北部,中部地区最小。针对SWAT模型的空间分析结果提出了该区非点源污染的防治措施。

关 键 词:大宁河流域  SWAT模型  农业非点源污染  空间分布

Abstract:SWAT model was used to calculate the agricultural non-point source pollution in Daninghe watershed.The runoff and the sediment data series from 2000 to 2004 were used to calibrate the parameters and validate the model.Results indicated that SWAT model was appropriate for Daninghe watershed.Then the calibrated model was used to calculate the spatial distribution of non-point source pollution.The calculated result indicated that the west part of the watershed was the serious soil erosion area,which is the sam...
Keywords:Daninghe watershed  SWAT model  agricultural non-point source pollution  spatial distribution
