| 摘要: |
| 通过对三峡水库支流童庄河库区的浮游植物进行调查,共检出浮游植物132种,其中蓝藻门23种,隐藻门2种,甲藻门3种,硅藻门55种,裸藻门3种,绿藻门46种.其中硅藻门的种类居首位,甲藻和隐藻则在数量上占优势.主要优势种为飞燕角甲藻(Ceratium hirundinella)和隐藻-种(Cryptomonas sp.).浮游植物的种类和数量随季节和水域不同而呈现差异.应用水质理化指标、污染指示种和污染指示群落评价童庄河水质,显示其水质为Ⅴ类,为β-中污型水体. |

| Abstract: |
| The paper introduced that there were 132 species of phytoplankton were identified during the survey period in TongzhangRiver district, Three Gorges Reservoir,including 23 species of Cyanophyta, 2 species of Cryptophyta, 3 species of Pyrhophyta, 55species of Bacillariophyta, 3 species of Euglenophyta and 46 species of Chlorophyta.Bacillariophyta has the most diversified spe-cies, while Pyrhophyta and Cryptophyta were the abundant ones.The dominant species were Ceratium hirundinella and Crypto-moms sp. The species and abundance of phytoplantkton varied with seasons and survey areas.Water quality assessment was calcu-laced by using the chemical and physical index, saprobic indicator and saprobic community indicator, overall evaluation result ofwater quality was V,and thep-type of moderately polluted type. |
