分别于2013年3月、7月、10月、12月对伊河龙门段进行4次采样，调查浮游植物的群落结构，并对水质进行评价。结果表明，在伊河龙门段中共鉴定出浮游植物7门、105种（属）。其中，绿藻门为52（属）种，硅藻门有23（属）种，蓝藻门21（属）种，裸藻门4（属）种，甲藻门、黄藻门和隐藻门各2（属）种。利用浮游植物群落结构和理化指标，结合生物多样性指数，判定伊河龙门段水质处于中营养型，达到地表水Ⅲ类水质标准。

In order to investigate the phytoplankton community structure and water quality, the sampling sites in Yihe River Longmen section were sampled 4 times in 2013 March, July, October, and December.The results indicate that 105 species of 7 phyla of phytoplankton were identified, including 52 species of Chlorphyceae, 23 spe-cies of Bacillariophyte, 21 species of Cyanophyta, 4 species of Euglenophyta, 2 species of Dinophyta, 2 species of Xanthophyceae, 2 species of Cryptophyta.Results from combining the phytoplankton community structure, physico-chemical index and biodiversity index show the water quality of Yihe River Longmen section is medium nutrient type, which reaches the water quality standard of classⅢ surface water.
