【摘要】 本文对2011年黄河干流及主要支流64个断面进行水资源质量评价,并对主要省界断面进行水质评价,将其与2010年水质进行对比分析,最后提出改善水质的对策。本文对评价项目、评价方法进行了详细介绍。评价结果表明:2011年黄河上游河段水质良好,黄河下游河段虽然水质超标,但是主要超标项目为氨氮,黄河中游水质污染比较严重,需要加强黄河流域的污染控制。更多还原

【Abstract】 Water resource quality is evaluated on 64 sections of Yellow River trunks and major tributaries in 2011,and major province boundary sections are evaluated. The evaluation results are comparatively analyzed with water quality in2010,and countermeasures to improve water quality are finally proposed. In the paper,evaluation items and methods are introduced in detail. Evaluation results show that water quality on the upper reaches of the Yellow River was excellent in2011,water quality on lower reaches of the Yellow River exceeded standards,but main substandard item is ammonia nitrogen,water quality pollution in the middle reaches of the Yellow River was more serious,and pollution control of Yellow River basins should be reinforced.更多还原
