以天津市14条主要地表河流2004-2011年期间的高锰酸盐指数、化学需氧量、五日生化需氧量、氨氮、石油类、挥发酚、总磷7项污染物含量为依据，对天津市主要地表河流的污染特性、差异性及变化趋势进行分析。结果表明：高锰酸盐指数、化学需氧量、五日生化需氧量和氨氮这4种污染物含量的均值从2004-2011年总体呈下降趋势；石油类含量不同年间变化不大；挥发酚和总磷呈典型的W型变化趋势。7种污染物含量均值在同一年不同水期有一定的差异性，但差异不显著。本研究补充了天津市多条主要河流连续多年水质情况分析统计的数据，研究结果可为天津市水环境污染防治、保护和治理提供依据。

Taking the content of seven kinds of pollution such as permanganate index ( CODMn ) , chemical oxygen demand (CODCr), Five days biological oxygen demand (BOD5), ammonia-nitrogen(NH3-N), petroleum, volatile phenol and total phosphorus ( TP) in fourteen main rivers in Tianjin from 2004 to 2011 as the reference , this paper analyzed the characteristics of water pollution , difference and change trend in the major rivers of Tianjin.The result shows that the average contents of COD Mn, CODCr, BOD5 and NH3-N appear a declining trend from 2004 to 2011;Petroleum changes little in different years;vola-tile phenol and TP prensents a typical W -shaped trend .The average content of seven pollutants in the same monitoring period have certain differences , but the differences are not significant .The paper supple-mented the data of water quality analysis and statistics in major rivers of Tianjin for many years .The re-sult can provide a basis for the prevention , protection and government of water environment pollution in Tianjing.
