摘　　要：为全面了解常州北市河底泥的N、P污染状况和N、P污染对3种功能微生物的数量影响,对其底泥表层样进行了为期一年的营养元素(N、P)检测和3种功能微生物的计数。分别运用单因子指数法和营养物含量评价标准法评价了营养元素(N、P),并对3种功能微生物数量与营养元素(N、P)的关系进行了研究。结果表明:氮磷属中等污染,TP污染总体略高于TN。可培养功能微生物菌落数随温度变化明显。氨氮与硝态氮,总磷细菌数量与自养硝化菌数量有明显的相关性(r>0.8)。To fully understand the pollutional situation of nitrogen and phosphorus in the Changzhou Taipei river sediment and the impact on the quantity of three kinds of functional microorganisms,this article study took one year detection on nitrogen and phosphorus in the surface sediment and counting on three kinds of functional microorganisms.Through single factor index method and nutrient elements evaluation standard method,nitrogen and phosphorus are evaluated,and at the same time the correlations between the quantity of three kinds of functional microorganisms and nitrogen and phosphorus were studied.The results showed that:the pollution of nitrogen and phosphorus belonged to moderate pollution level,overall pollution levels of TP was slightly higher than TN,the gross of functional microorganisms changed significantly with temperature.Ammonia and nitrate nitrogen,total phosphorus bacteria and autotrophic nitrifying bacteria had a significant correlation(r>0.8).
