基于2004~2010年宿州市5条主要河流的水质监测数据，分析水体中污染物 CODMn、BOD5、NH3-N、CODCr、TN、TP的时空动态变化特征，并利用内梅罗综合指数评价法对水质污染状况进行了评估。结果发现：除TP以外，其他5类污染物质量浓度均呈总体下降的年际变化特征，而在年内变化方面，各污染物总体呈“上升-下降-上升”特征，质量浓度高值集中于3~6月份；6类污染物质量浓度最高值均出现在奎河杨庄断面，而最低值除CODMn出现在沱河东关闸断面外，其余5类污染物最低值均出现在新汴河泗县汴河桥断面。评价结果表明，研究期内各河流水体均受到不同程度污染，其中奎河水质最差，而新汴河和浍河水质较好，多数河流断面水质较2004年有明显改善，其中以沱河芦岭桥断面最为显著。

Based on the water quality monitoring data of the five major rivers in Suzhou city from 2004 to 2010,the paper analyzed the spatial-temporal dynamic change characteristics of water pollutants as CODMn,BOD5 ,NH3-N,CODCr,TN and TP,and used Nemerow index method for the assessment of wa-ter pollution situation.The results show that:In addition to TP,the other five categories of pollutant concentrations showed interannual variation of the overall decline,but in terms of changes during the year,various pollutants generally have a “up-down-up”feature,high concentration values appear from. March to June;The highest concentration value of six class pollutants appeared in the Yangzhuang sec-tion of Kui River,but except that the lowest concertration of CODMn appeared in the Dongguanzha sec-tion of Tuo River,the lowest concentration values of the remaining five pollutants appeared in the Sixian Bian River Bridge section of New Bian River;The evaluation results show that:in the study period,all rivers are subj ect to different levels of pollution,among with the Kui River water quality is the worst, while the new Bian River and the Hui River's water qualities are better,most of the water quality of the river section has improved significantly compared with 2004,with Luling Bridge section of Tuo River im-proved the most.
