| 中文摘要: |
| 根据2010年9月大渡河河口浮游植物与水环境的调查，分析了大渡河河口浮游植物的分布特征及其与水环境指标的关系。结果表明：2010年秋季共鉴定浮游植物6门61属127种，优势种为变异直链藻、钝脆杆藻、尖针杆藻、缢缩异极藻、小颤藻等；浮游植物丰度变化范围为102960～290160 ind./L，生物量变化范围为0.0772～1.9717mg/L。聚类分析表明大渡河河口河道生境分为5个类型，浮游植物种类组成、现存量的分布与生境类型关系密切，但浮游植物与水质因子相关关系不显著。 |

| The data obtained in the Dadu River Estuary during Sep．in 2010 were analyzed for understanding the distribution features of phytoplankton and its relations with the environmental factors．Total 6 phylum，61 genera and 127 species of phytoplankton were identified．The main species are Melosira varians，Fragilaria capucina，Synedra acus，Gomphonema constrictum，and Oscillatoria tenuis．The phytoplankton abundance ranged from 102960 to 290160 ind./L，and the phytoplankton biomass ranged from 0.0772 to 1.9717mg/L．According to cluster analysis，the habitat of Dadu River Estuary were divided into 5 categories．The phytoplankton species composition and biomass distribution had close relationship with the habitat type．But the phytoplankton and water quality factors had no significant relationship． |
