摘要
2006年3月至4月底,在新安江屯溪水力自控翻板坝蓄水期和非蓄水期定点进行浮游植物调查,共采集到浮游植物39属种,隶属于4门。主要优势种为硅藻和绿藻。蓄水期的藻类丰度高于非蓄水期。依据调查结果选用"污染指示种"对翻板坝上游水域水质污染状况进行评价,结果表明:新安江屯溪城区段水质属乙型中污水。
From March,2006 to the end of April,fixed point carried on the phytoplankton investigation in the Xinanjiang river Tunxi water power automatic control vane dam the inpoundment time and the non-inpoundment time.A total of 39 genera species phytoplankton belonging to 4 phyla were observed.The dominant species were Bacillariophyta and Chlorophyta.The inpoundment time algae abundance is higher than the non-inpoundment time.Selected＂saprobic indicators＂to the water pollution condition has carried on the appraisal to the vane dam upstream.Consequence indicates,the Xinanjiang river Tunxi city sector water quality is in the middling mesotrophication.
