对南淝河当涂路桥上游至董铺水库河段的沉积物进行系统地分析，测定了有机质、总磷（ TP）、总氮（ TN）及重金属Pb、Cr、Zn的含量。研究了沉积物中各个测定指标的垂直分布规律，各采样点的污染指标含量均呈现随着取样深度的增加而减少。用地累积指数法和潜在生态危害系数法对沉积物中重金属污染作出了评价，结果表明，南淝河沉积物中重金属含量属于轻度生态危害。对沉积物中的有机质和有机氮运用有机指数和有机氮评价法进行评价，发现南淝河沉积物中的有机质和有机氮均处于超标状态。

This paper systematically analyzed the sediments in the reach of Nanfei river from Dangtu Road bridge to Dongpu reservoir.The contents of organic, total phosphorus, total nitrogen, lead, chromium and zinc were determined.The vertical dis-tribution of each measurement indicators in the sediments were studied , showing that the content of each measurement indicators in every sampling point was decreasing as the sampling depth increased .The cumulative index and the potential ecologic risk fac-tor were used to evaluate heavy metal pollution in the sediment .The results showed that the content of heavy metals in sediments Nanfei River was mild ecological harm.The organic index and the organic nitrogen evaluation were used to evaluate the influences of organic and organic nitrogen in sediments.The results showed that the contents of organic and organic nitrogen in sediment of Nanfei River were in the overweight state.
