黄河潼关—小浪底河段严重污染状况及原因

１９９９年１月中旬以来，黄河干流潼关—小浪底河段遭受严重污染，龙门以下河段水质均超过Ⅴ类，主要污染因子为ＣＯＤＣｒ，污染物主要来自渭河、汾河、涑水河等支流及入黄排污口。造成这次污染的原因除黄河流量小等自然因素外，还有流域内各省（区）水污染防治不力、污染治理严重滞后等人为因素。这次污染严重影响了沿黄城市生活和生产供水。因此，建议加强流域水资源统一管理，建立流域水资源保护领导小组，加强黄河水资源保护法规建设，将黄河列入全国水污染防治和水资源保护工作的重点，加大水污染防治力度

Severe Pollution of the Reach from Tongguan to Xiaolangdi in the Yellow River and the Causes

The main pollution factor is COD with major pollution material come from Wei river, Fen river, Sushui river and other Yellow River branches as well as pollution outlets. Except for the natural cause of small discharge in the Yellow River, the main reason for the pollution, which has seriously influenced water supply for production and daily use of the cities along the river, is insufficient control of water pollution, delayed management measures and other artificial activities in provinces in the basin.
