摘　　要：为了解乌江渡水库水质变化趋势,对2002～2010年乌江渡水库水质监测结果进行了分析。采用综合营养状态指数法、污染分担率法、秩相关系数法,对水库富营养化等状况进行评价。结果表明,近年来,乌江渡水库总磷和总氮污染分担率之和达78%,是水库主要污染物,水库水质从大岭岗、偏岩河口到大坝,富营养程度逐渐加重;水库中总氮、氨氮、粪大肠菌群和五日生化需氧量也均呈显著上升趋势。建议加大乌江渡水库水质中总磷和总氮等的监测力度,加强防护与控制管理。Based on 2002 -2012 monitoring data, we assessed the eutrophication ot W ujlangau ttes- ervoir by comprehensive nutrition state index, pollution share rate and rank correlation coefficient. It found that during this term, TN and TP, contributing to 78% of total pollution load in the reservoir, were the main pollutants. The eutrophication level went up along Dalinggang Daba. The concentrations of TN, NH3 - N, fecal coliform and BOD5 increased year. Close monitoring of TN and TP should be performed for the reservoir. - Pianyan Hekou- significantly year by
