摘　　要：水库建成蓄水后,库底土壤中氮、磷的浸出会对库水水质会产生一定影响。本文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,分析研究了土壤中氮、磷浸出对库水中总氮、总磷浓度的影响。实验结果表明,总氮、总磷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,源于土壤的含量较低,对库水水质未产生明显不良影响。Nitrogen and phosphorous in submerged soil will be dissolved, influencing water quality when the reservoirs begin 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 was used as a case. On the basis of field investigation, simulative experiment was conducted with distilled water and simulative water at the same time. The results revealed that concentrations of total nitrogen,and phosphorus changed under the experimental conditions, and the change in simulative water was less significant than in the distilled water. Nowerer the submerged soil will not exert significant adverse effect on water quality on the whole.
