【摘要】 2010年9月对东辽河流域的浮游植物群落进行了调查,共检出浮游植物6门,浮游植物主要由硅藻、绿藻和裸藻组成。文中运用典范对应分析(CCA)对东辽河流域所有采样点的主要浮游植物与6个水环境因子关系进行研究。结果表明,总氮和溶解氧是影响东辽河流域浮游植物群落分布的主要水环境因子。更多还原

【Abstract】 The phytoplankton communities were investigated in Dongliaohe river basin in September 2010 and 6 phylum of phytoplankton were detected.The phytoplankton mainly contains the diatom,green algae and euglena. The paper studies the relationships between the main phytoplankton at all sampling points and six water environmental factors by using the canonical correspondence analysis in Dongliaohe river basin. The results show that the total nitrogen and the dissolved oxygen are the main water environmental factors for distribution of phytoplankton community in Dongliaohe river basin.更多还原
