| 摘 要： | 选取北京市重要的地表水源密云水库作为实例研究,在识别影响富营养化发生的主要限制因子的基础上,采用外源营养盐输入对富营养化作用的流水藻类培养试验(AGP)方法,并结合数学方法拟合富营养化水体发生的阈值.研究表明,根据富营养化水体各水质指标之间的回归关系,确定出能够反映富营养化的水质指标阈值.运用水质模型模拟富营养化过程,进行基于阈值的富营养化风险评价,构建了富营养化风险评价方法体系,提供了一种基于阈值的水体富营养化风险评价的方法. |

| Abstract: | Miyun Reservoir,a major surface water source to Beijing,was selected as a case study.The AGP test method was selected to evaluate sources of external nutrient input to the eutrophic water,combined with mathematical methods fitting the eutrophic water body threshold.The indicators of the eutrophication threshold were identified according to the regression relationships among indicators of water quality.The eutrophication process was simulated by a water quality model to assess the risk of eutrophication.Foll... |
