Abstract:

运用数学模型模拟非点源污染物的空间分布及其输移转化机制,是当前农业非点源污染研究中的重要手段和途径之一。流域尺度长时段分布式水文模型SWAT(soilandwaterassessmenttool)应用于我国南方许多流域的非点源污染模拟上都取得了较好的结果。利用SWAT模型建立了东北图们江流域非点源污染数据库,对该流域(中国一侧)划分为5个小流域46个水文单元,分别进行了水文模拟、降雨径流和土壤侵蚀量计算。结果表明,图们江流域农业非点源污染主要的发生区在流域中部,海兰河和布尔哈通河交界的区域内。该区内有机氮和有机磷的非点源污染负荷明显高于其他地区,推测认为该区域为延边州首府延吉市所在地,城市建设和经济发展带来了繁荣,也造成了局部地区的植被破坏、土地裸露,水保能力下降,因此水土流失现象比较严重。另外,通过分析流域内有机氮和有机磷的时空变化特征发现,2007年延吉、龙井地区为氮磷营养物非点源污染最大发生区(有机氮9.76t·a-1,有机磷1.24t·a-1),而2008年除延吉、龙井地区外,珲春地区有机氮和有机磷非点源污染均有加重的趋势(分别由1.39t·a-1上升到3.82t·a-1,0.17t·a-1上升到0.48t·a-1);氮
