海河干流浮游动物群落结构的初步研究
Initial research on community structure of zooplankton in mainstream of Haihe River
摘要
Abstract
The resource of zooplankton in mainstream of Haihe River was investigated from May to October in 2009. Nine stations were researched and monitored. The results showed that there were 32 species of zoo-plankton, including 12 species of Rotifera, 8 species of Copepoda, 9 species of Cladocera and 3 species of Protozoa. In each month, the diversification of the densities was consistent with the biomass. The maximum appeared both in May, and they were 1 980.00 ind/L and 65.30 mg/L respectively. ANOVA analysis indicated that the densities and biomass were not affected by the months and stations (P >0. 05). They displayed different density levels at different stations and stages. According to the Margalef method, Haihe River belongs to a mid-heavy filth type. Combining with the environmental factors, the paper discussed the biological reasons. Further, a rationalization suggestion was proposed to repair the water quality of Haihe River.关键词
