摘　　要：采用SWAT模型模拟了湘江株洲段汞的面源污染负荷,结果表明,SWAT模型可对地表径流量、产流量、土壤侵蚀量进行较好的模拟。研究区汞面源污染负荷总量约为789.7kg/a,其中受污染土壤是面源负荷量的主要来源,占总污染负荷的91.38%。汞面源污染受区域降雨量引起的土壤侵蚀的影响尤其明显。The SWAT model was used to simulate the mercury non-point source pollution of Xiangjiang river i Zhuzhou section.The results showed that the SWAT model could well simulate the runoff volume and soil erosion amount. The total amount of Mercury non-point source pollution load in the studied area was about 789. 7 kg/a,of which the contaminated soil was the main source of non-point source load,accounting for 91. 38% of the total pollution load. Mercury pollution was especially affected by soil erosion caused by regional rainfall.
