石家庄市地表水源氮、磷污染分布特征

氮、磷物质的输入是造成地表水源富营养化的主要原因，研究氮、磷污染分布特征对于了解其来源及其流失规律具有重要意义。笔者对石家庄市地表水源现状及环境背景水质进行了调查和分析，结果表明：岗南水库氮、磷污染丰水期比枯水期重；氮、磷元素形态及其流失形式均表现为非点源污染特征；汛期洪水输入是岗南水库氮、磷污染物的主要来源方式。

Distribution Characteristics of Nitrogen and Phosphorus Pollution in the Surface Water Source of Shijiazhuang City

The main reason for eutrophication of surface water source is the import of nitrogen and phosphorus. And it is of significance for understanding their source and loss to study the distribution characteristics of nitrogen and phosphorus pollution. The author investigates and analyzes the current situation of Shijiazhuang's surface water source and water quality of environmental background. The result shows that the pollution of nitrogen and phosphorus is more serious in the period of high water than in the period of low water in the Gangnan Reservoir; the form and loss of nitrogen and phosphorus are both in the non-point source pollution; the nitrogen and phosphorus pollutant of this reservoir are mainly from flood import in the flood season.
