摘  要：
2014年5、8和10月分别对渤海西部滨海带陆域海河、马颊河、黄河COD_(Mn)和TOC进行测定,分析各河流中COD_(Mn)与TOC的浓度变化趋势,并开展二者相关性研究。结果表明,海河、马颊河和黄河COD_(Mn)浓度范围分别为2.87~20.25、5.83~14.44、1.80~4.80 mg/L,TOC浓度范围分别为4.26~9.51、5.05~26.62、3.00~16.27 mg/L,其中马颊河有机污染最重,黄河最轻;在海河和马颊河中的两种污染物浓度从上游到下游均呈升高趋势,但在黄河中的变化不大。海河和黄河COD_(Mn)和TOC浓度均值受采样时间变化的影响很小,而马颊河中TOC浓度均值在5月和10月有显著差异。三条河流各月份的COD_(Mn)和TOC的相关性差异较大,COD_(Mn)和TOC协同变化趋势越相似,相关性越显著。

摘  要：
In order to analyze the variation trend of the COD_(Mn) and TOC concentration and conduct correlation study, the concentration of COD_(Mn)and TOC in the Haihe river,the Majia river and the Yellow river of the western Bohai sea littoral zone were measured in May,August and October 2014,respectively. The results showed that the concentration range of COD_(Mn) was 2.87~20.25,5.83~14.44,1.80~4.80 mg / L and concentration range of TOC was 4.26~9.51,5.05~26.62,3.00~16.27 mg / L,respectively.The results showed that organic pollution was most serious in Majia river and slightest in the Yellow river. Concentrations of COD_(Mn)and TOC increased from upstream to downstream in the Haihe river and majia riber, while little change was found in Yellow river. The mean concentration of COD_(Mn)and TOC was slightly affected by sampling time change. But mean concentration of TOC in Majia river showed significant difference in May and October. The correlation between COD_(Mn) and TOC showed significant difference in three rivers. With the trend of the coordinated variation of COD_(Mn)and TOC becomes more and more similar, the correlation becomes more and more obvious.
