摘　　要：运用国际上通用的多个经验统计磷模型预测千岛湖目前的磷浓度水平,其中第6个模型最适合用于千岛湖的预测预报.利用该模型预测了磷负荷量分别减少1/4、1/2、3/4情况下,千岛湖水体中总磷浓度的响应。同时针对千岛湖营养水平控制的短、长期目标,利用模型计算出了所允许的总磷负荷量及入湖磷浓度。Total phosphorus concentration is predicted by using several international general statistic models. The value that the sixth model predictes is relatively consistent to the practical value. In addition, the responses of total phosphorus concentration are predicted if the loads of total phosphorus are decreased by 25%,50% and 75%, respectively. At the same time, we address the short, long period aim in controlling the water pollution in Qiandaohu lake. The permitted load of total phosphorus and total phosphorus concentration of inflow water are calculated by using the sixth model.
