南水北调中线汉丹江(陕西段)流域水质预测

Water quality prediction of Middle Route of South-to-North Water Diversion Project in water district(Shaanxi)

目的预测南水北调中线工程陕西水源区水质。方法率定参数,利用一维水质模型预测水质。结果预测结果表明,不满足水质要求的功能能枯水年占90.9%,平水年占86.4%,丰水年占68.2%。结论大部分水环境功能区将不能满足水质要求。

Aim To forecast water quality of Shaanxi district of Middle Route of South-to-North Water Diversion Project.Methods One-dimensional water quality model has been taken to forecast the water quality.Results The results showed that functional areas didn′t meet water requirement accounted for 90.9% in dry year,86.4% in normal year,and 68.2% in wet year.Conclusion Most of water environmental function areas didn′t meet the requirement of water quality.
