摘　　要：根据氮磷物质平衡原理计算抚仙湖氮、磷污染物负荷平衡,抚仙湖每年输入的氮磷负荷为:总氮1303.1 t/a,总磷66.3 t/a;输出的氮磷负荷为:总氮0.54 t/a,总磷0.034 t/a;每年增加的氮磷负荷为:总氮1302.56 t/a,总磷66.27 t/a。增加的氮磷负荷中,进入水体的负荷(库容变化量)为:总氮532.14 t/a,总磷0.32 t/a;剩余的总氮770.42t和总磷65.95t可能向沉积于底泥、供藻类和大型水生植物生长利用等其它方向分流。The nitrogen and phosphorus balance were calculated in Fuxian Lake according to the balance principle.The annually input of total nitrogen was 1303.1 t/a, and total phosphorus was 66.3 t/a. The annually output of to-tal nitrogen was 0.54 t/a, and total phosphorus was 0. 034 t/a. Annual increase of total nitrogen was 1302. 56 t/a,and total phosphorus was 66.27 t/a. Some of the annual increasing pollution load entered to the water body （TN532. 14 t/a, TP 0.32 t/a）. The left （TN 770. 42 t/a, TP 65.95 t/a） might go to substrate sludge, air, algae,hydrophyte, and etc.
