摘　　要：采用多管发酵法(MPN法)测定大肠菌群数和粪大肠菌群数,稀释平板法测定细菌总数,并进行了浮游生物检测,以此对白河南阳段水质做出初步评价。结果表明:上游白河桥段水质稍好;铁路桥段和瓦店桥段中度污染。Coliform group counts and fecal coliform group counts were determined by most probable number (MPN ) and bacterium total amounts were measured with dilute platform method. The planktonic organisms were also identified under microscope.The water quality in the section of Nanyang of River was given preliminary appraisal on coliform group counts, fecal coliform group counts, bacterium total amounts and the plentons. The study revealed that the water quality of Baihe Bridge section was better and the water of railway bridge as well as Wadian Bridge was mid-contaminated.
