陡河上游及库区水体中氮素的迁移过程

Nitrogen Migration Process in Water Body of the Upstream and the Reservoir Area of the Douhe Reservoir

分析了近10年陡河水库降水及外调水等来水量变化趋势，随着库龄的增大，库内淤积物不断增多，结合陡河水库水质监测资料对陡河河道及水库库区水体氮的迁移过程进行分析，探讨陡河水库库区及上游水体中氮的迁移规律，提出具有针对性的治理措施。

The paper analyzes changing trend of water inflowing amount of the rainfall,diverted water of the Douhe reservoir recent ten years. With the increase of reservoir age,deposit in the reservoir is increasing continuously. Combining with water quality monitoring materials of the Douhe reservoir, the paper analyzes migration process of water body in the Douhe channel and the reservoir area, and discusses migration rule of Nitrogen in water body of the upstream and the reservoir area of the Douhe reservoir so as to provide specific treatment measures.
