摘要
氮磷是三峡库区水质的决定因素。在分析三峡水库中氮磷污染现状和特点的基础上,运用统计法、通量法和模型法估算了三峡水库氮磷污染物的上游来量和库区产生量,以及库区点源负荷、面源负荷,得出了库区氮磷污染主要来自库区上游和库区面源污染的结论。
The elements N and P are crucial to the water quality of Three Gorges Reservoir. After the present situation and characteristics of N and P pollutions analyzed and statistical method, flux method and modeling method adopted to estimate the quantity of N and P from upstream and reservoir area, the pollution loads of point and no-point pollution source, the conclusion that the main source of N and P pollutants are from both upstream of Reservoir and non-point pollution.
