中文摘要:
      针对目前河道型水库TP评价标准存在争议的水环境管理实际问题,提出了基于水龄权重的TP评价标准参考值计算方法,并以三峡水库为例对方法进行展示,为河道型水库水环境精细化管理提供参考。基于水龄权重的三峡水库TP评价参考值计算内容包括:①以朱沱为控制断面,基于EFDC水动力模型模拟2017年三峡水库水动力过程,计算出三峡水库库区干流主要断面逐日水龄。②依据水龄将三峡水库各断面分为河流型水体(朱沱-清溪场,逐日水龄均小于20 d)、河流型-过渡型混合型水体(苏家-白帝城,逐日水龄在小于20 d和20~300 d变化)、过渡型水体(巫峡口-木鱼岛,逐日水龄均在20~300 d)。③计算基于水龄权重的过渡型水体TP评价标准参考值,并据此对2017年三峡水库主要断面水质因子进行评价,结果表明三峡水库泄水期早期(1―2月),白帝城以下断面水质污染指数较高,风险较大。
英文摘要:
      In this study, a TP assessment standard reference value for river-type reservoirs was proposed based on the reservoir residence time, and Three Gorges Reservoir (TGR) was chosen as an example to demonstrate the calculation method. The aim was to provide a reference for managing river-type reservoirs. First, an EFDC (Environmental Fluid Dynamics Code) model was used to simulate the hydrodynamics of Three Gorges Reservoir in 2017, and the residence time of water in different sections of the Three Gorges Reservoir mainstem were calculated using the Zhutuo reach as the control section. Then, the monitoring sections in Three Gorges Reservoir were classified into three types, according to water residence time: (1) River (residence time <20 days): Zhutuo, Jiangjindaqiao, Fengshouba, Cuntan, Qingxichang; (2) River-Transitional (residence time 20-300 days): Sujia, Shaiwangba, Baidicheng; (3) Transitional (residence >300 days): Wuxiakou, Huanglashi, Muyudao. Finally, the assessment standard reference values for TP for transitional sections were calculated based on the water residence time. The TP concentrations in transitional sections in Three Gorges Reservoirs in 2017 were determined based on the calculated assessment standard values of TP, which was used to assess the TP pollution of Three Gorges Reservoir. The evaluation results show that the TP pollution indices for Baidicheng, Wuxiakou, Huanglashi sections were high in January and February and indicate a higher pollution risk. .
