摘　　要：总磷是湖泊富营养化的重要指标,本文采用零维质量平衡模型对西湖治理前、后的20年总磷浓度年平均值及多年逐月变化进行验证,并预测新的引水方案对改善西湖水域总磷的总体影响,同时建立西湖平面二维水动力水质模型,研究引水方案对改善西湖总磷平面分布的效果。Total phosphorus is a key eutrophication factor of the water body in the west lake of Hangzhou.This paper adopts a zero-dimensional mass balance model to analyze the influence a new water supply project on the total phosphorus（TP）.The model was validated by the measurements of yearly average and the monthly variation of the total phosphorus concentration over 20 years before and after the project completion.A depthintegrated 2D numerical water quality model of high resolution was also developed to study the improvement of the total phosphorus concentration distribution by the project.
