摘　　要：基于鲁湖流域的空间和属性数据,应用SWAT模型对其流域农业面源氮、磷入湖通量进行了计算。结果表明,2014年鲁湖流域农业面源氮、磷年入湖通量分别为550t/a和28t/a,其氮、磷入湖通量最大的月份均出现在降雨量较大的五月,分别为85.4t/月和4.4t/月;郑店镇、法泗镇农业面源污染对鲁湖的贡献最大,应作为重点控制区域。Based on the spatial and attribute data of Luhu Watershed,SWAT model is applied to calculate the agricultural non-point source nitrogen and phosphorus loading from Luhu Watershed into the lake.The results show that Luhu Watershed agricultural non-point sources of nitrogen and phosphorus loading is 550t/a and 28t/a in 2014,its largest loading month into the lake occurred in May,respectively,85.4t/mon and 4.4t/mon,when the rainfall is greater than other month.Zhengdian and Fasi District have contributed largely to Luhu agricultural non-point source pollution.
