摘要: 以2004年大同市御河河道流经的洪水为研究对象,对其流量、含沙量、氮素含量做了测定和比较,研究结果
表明:洪水中上清液中的氮素含量远远小于下层泥沙中的氮素含量,洪水中所含氮素含量伴随含沙量的多少而增减,增
减规律近似呈现线性关系,这一研究成果为有效利用洪水提供了重要依据。

Abstract: Towards the research on flood water of Yuhe River in Datong city during 2004, this paper measured and compared
their discharge, sediment concentration, nitrogen content. The result showed that the nitrogen content of the sediment is greatly
larger than that of supernatant fluid. The toatl nutrient of floods increases as the sediment concentration increases, and there is
nearly a linear relationship between them, the result offers impotant reference to the feasibility of effective use of flood.

 Key words: floods;discharge;sediment concentration;nitrogen content
