摘要
为研究袁河浮游藻类群落结构及其水质状况,于2010年3月(枯水期)及6月(丰水期)在袁河进行采样分析。2次调查共观察到浮游藻类6门45属89种。藻类细胞密度变化范围为1.79×104～40×104个/L;生物量变化范围为0.0188～2.2816mg/L。采用指示生物法和生物多样性指数法对水环境进行评价,评价结果表明袁河水质处于轻度或中度污染。
Sampling was carried out in March and June 2010 in order to study structure of phytoplankton community and evaluation of water quality in Yuanhe River.Total 6 phylum,45 genera and 89 species of phytoplankton were identified.The phytoplankton abundance ranged from 1.79×104 cells/L to 401×104 cells/L,and biomass ranged from 0.0188 mg/L to 2.2816 mg/L.Biological assessment of water pollution and eutrophic condiction was conducted by using the method of indicator organism and biotic index.The results indicated that the water quality was mild or moderate polluted.
