【摘要】 通过对黑龙江哈东沿江湿地的调查分析,共获得哈东湿地浮游动物3门35科67种,其中原生动物门18科,节肢动物门10科,轮虫动物门7科。全年生物量及密度在0.2250~0.9023mg/L和2040~6753个/L之间;获得底栖动物3门13科26种,其中节肢动物门最多,有8科,其次是软体动物门4科,环节动物门1科,全年生物量及密度为10.2g·m-2~36.7g·m-2和24.2ind·m-2~80.52 ind·m-2之间。生物评价结果表明,哈东湿地无污染或较轻污染,群落结构也相对比较稳定。更多还原

【Abstract】 We investigated zooplankton and zoobenthos in Hadong wetland of Hei Longjiang province,got zooplankton that belonged to 3phylum,35 families and 67 species which have 18 families of Protozoa,10 families of Arthropod,7 families of Rotifera Phylum. The annual total biomass and density of zooplankton were between0.2250~ 0.9023mg/L and 2040 ~ 6753/L. Zoobenthos belonged to 3 phylum, 13 families and 26 species, 8families of arthropod was most,then followed by 4 families of Mollusca,1 families of annelid. The annual total biomass and density of zoobenthos were between 10.2g·m-2~36.7g·m-2and 24.2ind·m-2~80.52 ind·m-2. The results showed that there were no pollution or less pollution in Hadong wetland and the community structure was relatively stable.更多还原
