摘要
2012年对松花江哈尔滨段浮游动物群落结构进行调查研究,并结合理化指标评价法对水质进行评价.结果显示:共鉴定出浮游动物40种,其中原生动物9种,轮虫27种,枝角类2种,桡足类2种;污染指示种34种,其中寡污性为10种,o-β中污性为6种,β-中污性为9种,β-α中污性为4种,α-中污性为5种;全年平均丰度为1042.0 ind./L,生物量为0.078 mg/L.常见种有萼花臂尾轮虫(Brachionus quadridentatus)、螺形龟甲轮虫(Keratella cochlearis)和针簇多肢轮虫(Polyarthra trigla),均为中污染指示种;各样点污染程度在季节变化和全年变化中均表现一致,总体是上游水质优于下游,季节污染程度是夏季>秋季>春季.整体评价结果显示,松花江哈尔滨段水体已处于中富营养水平、中度污染状态.本研究结果可为松花江水质生态评价、水环境监测及水资源管理提供重要的理论依据.
In 2012, the zooplankton community structure in Harbin section of Songhua River was surveyed, and chemical index evaluation methods were used to assess the condition of water quality. A total of 40 species of zooplankton were found, including 9 species of protozoa, 27 species of Rotifera, 2 species of Cladocera, and 2 species of Copepoda. There are 34 species which could be treated as polluted indicators, in which 10 species arc in light level, 6 species are in 0-6 in middle level, 9 species are in middle level, 4 species are in ^-~x middle level, and 5 species are in tx middle level. The annual average richness is 1042.0 ind./L, and the biomass is 0.078 mg/L. The common species are Brachionus quadridentatus, Keratella cochlearis and Polyarthra trigla, which are all mesosaprobity pollution indicators. The pollution degree of all kinds at the sample sites is consistent with the seasonal variation and the annual variation, where the water quality of the upstream is better than that of the downstream. The ordination of seasonal pollution degree from strong to weak levels is summer 〉 autumn 〉 spring. Overall evaluation results showed that, Harbin section of the Songhua River has been polluted in middle eutrophication level and in moderately polluted state. This study reflects that the current status of water quality objectively provides the important scientific basis for the Songhua River water quality and ec- ological assessment, water environment monitoring and water resources management.
