摘　　要：采用底栖动物、着生生物指标对嫩江"十一.五"期间水质进行综合评价,结果嫩江水体污染总体在轻污染和中污染之间;各断面污染情况为拉哈、浏园、江桥、富上逐渐加重;2006年至2010年期间水质变化不明显,但平水期略重于丰水期。We evaluated water quality of Nenjiang river in the eleventh five-year-plan with benthic animal and periphyton indicators. The result showed that pollution of Nenjiang river was between light pollution and medium pollution. Pollution gradually increased from Laha section, Liuyuan section, Jiangqiao section to Fus-hang section. Water quality did not change significantly from 2006 to 2010 , but pollution in normal river flow period was slightly heavier than high water flow period.
