摘　　要：近年来，在黄河流域工农业高速发展的同时，黄河水污染也日趋严重，且以有机物污染为主。通过分析认为，黄河水质监测中采用的反映有机污染的主要指标ＣＯＤＭｎ已不能客观反映黄河水体的有机污染程度，而ＣＯＤｃｒ的代表性较好；黄河多泥沙的特点给 ＣＯＤｃｒ的监测带来种种困难，根据以往的一些研究结果，作者提出在黄河河口镇以上断面ＣＯＤＣｒ的监测可按照国家监测标准要求执行，河口镇以下断面非汛期时按照国家监测标准要求进行监测。汛期则仅监测清水中的ＣＯＤｃｒ，但监测结果不能作为国家环境治理措施制定的依据。In recent years, along with speedy development of industry and agriculture in the Yellow River basin, the water pollution becomes more and more intensified and it is mainly organic contamination. It is shown from analysis that the COD.. that used as indicator to monitoring organic pollution before is not objective in description of water pollution degree while CODcris of better representative. There are a lot of difficulties in monitoring COD., because of much sediment content in the Yellow River. Based on the research achievements before, it is put forward in the paper that CODcr monitoring can be conducted according to the state monitoring standard in the upper reaches of Hekouzhen, and so do for the reaches lower Hekouzhen in non--flood seasons. Only CODcr in clear water should be monitored in flood seasons, but the results can not be taken as the basis for stipulating environmental management treatments at the state level.
