摘要
南水北调东线后续工程对于保障北京、天津等重要区域的供水安全,复苏河湖生态环境有着重要的意义。在收集常规断面数据资料和补充监测的基础上,评价黄河以北段输水沿线河湖现状水质,并进一步分析输水干线主要河流及调蓄水库近10 a水质变化趋势。经分析发现,水质风险存在于现状水质较差的一期输水河段小运河、七一河、六五河以及南运河部分河段。
The follow-up project of the East Route of the South-to-North Water Diversion Project is of great significance to ensure the safety of water supply in important areas such as Beijing and Tianjin and revive the river and lake ecological environment. Based on the collection of conventional section data and supplementary monitoring,this paper evaluates the current water quality of rivers and lakes along the water transmission line in the north of the Yellow River,and further analyzes the change trend of water quality of main rivers and regulation and storage reservoirs in recent ten years. According to the analysis,the water quality risk exists in the Small Canal,Qiyi River,Liuwu River and some sections of the South Canal of the water transmission section of the First Phase with poor water quality.
