摘　　要：该文基于汤逊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、磷入湖通量进行计算分析。结果表明2014年汤逊湖流域农业面源氮、磷年入湖通量分别为490 t/a和31.15 t/a,其氮、磷入湖通量最大的月份均出现在降雨量较大的5月,分别为59 t/月和5.58 t/月;东湖高新区和江夏区的农业面源污染对汤逊湖的贡献最大,应作为重点控制区域。Based on the spatial and attribute data of Tangxun Lake watershed, SWAT model was used to simulate the agricultural non-point source of nitrogen and phosphorus loading from Tangxun Lake watershed into the lake. The results showed that in 2014 Tangxun Lake watershed agricultural non-point sources of nitrogen and phosphorus loading is 490 t/a and 31.15 t/a, with the largest monthly loading into the lake occurred in May, when the rainfall is greater than other months,respectively 59 t/mon and 5.58 t/mon. Jiangxia District and East Lake High-tech Zone should be key areas for the control of agricultural non-point source pollution due to their contributions to the Lake
