黑龙江黑河江段藻类植物群落与环境因子的典型对应分析

摘要

The algal community was studied in Heihe channel in Heilongjiang River during May to October of 2006-2007, according to the taxon and relations between algal assemblage structures and environmental variables based on data from six monitor stations, and was analyzed by use of Canonical correspondence analysis. It revealed that biology oxygen demand, total phosphorus, water temperature and chemical oxygen demand from 7 water environmental variables are significant fractions of the distribution and variation of algal community. CCA result indicates that, the algal community and space distribution are correlated with environmental variables, the variety of the algal community may become a useful monitor for fiver environments.%2006-2007两年的5-10月期间,分别在黑龙江黑河段水域进行藻类植物的生态调查,在藻类分类的基础上,应用典型对应分析揭示黑龙江黑河江段6个监测点藻类植物的种群结构与环境因子之间的关系.生化需氧量、总磷、水温和化学需氧量等是影响藻类植物群落分布的主要因素,藻类植物的群落结构随着这些环境因子的变化表现出一定的空间差异,说明藻类植物的群落变化和空间分布与环境因子高度相关.
