| 摘 要： | 北方干旱区水库具有防洪、灌溉、城市供水多种功能，其富营养化控制具有重要意义。以对汾河水库水质长期监测数据为基础，结合水动力模型、物质输移扩散模型及富营养化生命过程建立富营养化耦合模型，研究不同情景下水库流场特征及营养物质的时空分布规律。研究表明，水库部分区域已发生富营养化，且库区内污染物浓度超标范围较大，提出上游排放口污染物削减方案，为汾河水库乃至整个北方干旱地区水库的富营养化控制提供技术支持。

| Abstract: | Reservoirs are indispensable because of their flood prevention,irrigation,municipal water supply,and other functions. Therefore,eutrophication control is of notable importance in northern areas.In this study,a eutrophication-coupled model was established based on the data from long-term water quality monitoring in the Fenhe reservoir.In addition,a hydrodynamic model,an advection dispersion model,and biological processes were utilized.The states of water flow and laws of nutrients diffusion also were studied under varying conditions.The results showed that part of the reservoir was affected by eutrophication,and the polluted areas were large.Moreover,a nutrients reduction plan was proposed upstream.This study provides technological support for eutrophication control in Fenhe and other reservoirs in the northern areas. |
