摘　　要：以南水北调中线工程的调蓄水库———瀑河水库为例 ,在现场调查基础上 ,使用蒸馏水和模拟水分别进行模拟实验 ,分析研究了库水中氮、磷、COD、重金属等组分的特征及其变化 .实验结果表明 ,不同形态的氮、总氮、总磷、COD、重金属的浓度均发生一定程度的变化 ,且模拟水中的浓度变化小于蒸馏水中的变化 ;但从整体趋势看 ,各组分源于土壤的含量较低 。The submerged soil will dissolve in water and influence water quality when a reservoir begins to run. In this study, the Bao He (Bao River) Reservoir with the functions of adjusting and storing water at the mid route of South to North Water Transfer Project is taken as an example. On the basis of field investigation, a simulative experiment is conducted with distilled water and simulative Water at the same time. The results revealed that the concentration of different forms of nitrogen, total nitrogen, total phosphorus, COD, and heavy metals has changed under the experimental conditions, and the change in simulative water is less than that in distilled water, but the submerged soil will not exert significant adverse effect on water quality on the whole.
