摘　　要：在福州市内河的主要河道设置12个采样点,逐月定性、定量采集浮游动物,同步测定5项化学指标.采用指示生物法和生物多样性指数法,对福州内河水质进行生物学评价,同时进行营养型的确定和黑臭率评价.评价结果表明,福州内河的污染等级为甲型至乙型中污,富营养型,黑臭状况较差.与前人的调查结果相比,引水冲污对内河治理有一定的作用,但并不能从根本上改变内河的水质状况.还探讨了内河污染的成因并提出治理建议.12 sampling stations were set up in Fuzhou's inner river and zooplankton were collected qualitatively and quantitatively in every month. At the same time , five chemical indexes were measured. The water quality was evaluated by using the biological indicator methods and diversity indexes. Nutrition type and black and fetid rate were also determined . The results indicated that water quality in Fuzhou's inner river was defined from α to β type of medium pollution . Nutrition type was rich and black and fetid rate was quite worse. Compared with the research in the past, eliciting water to wash the pollution away has some effects on the river 's harnessing , but it can't change the water quality essentially .The paper discussed the reason of river's pollution and put forward some harnessing suggestions .
