中文摘要:
      2015年对宜兴莲花荡水系四个季节浮游动物调查,共鉴定出浮游动物136种,其中,原生动物72种、轮虫39种、枝角类13种、桡足类9种、其他幼虫及卵3种。群落结构以原生动物和轮虫小型浮游动物为主。浮游动物的年平均密度为14 664 ind/L,年平均生物量为4.903 mg/L,生物多样性指数H′年平均值为2.26。浮游动物密度以及生物量随季节变化比较明显。对浮游动物密度、生物量、多样性指数与水质指标进行Pearson相关性分析,发现总氮(TN)、氨氮(NH4+-N)以及溶解氧(DO)是影响浮游动物密度的主要因素。结合生物多样性指数评价方法以及优势种情况,判定莲花荡水系整体处于中污型。
英文摘要:
      Investigation on the zooplankton of Lianhuadang River System which feeding into the Taihu Lake in Yixing in four seasons within a year were carried out in 2015. Total of 136 species of zooplankton were identified including 72 species of Protozoa, 39 species of Rotifer, 13 species of Cladocera, 9 species of Copepoda and 3 unkown species by the larvae. Community structure was mainly made up of small zooplankton, including Protozoa and Rotifer. The annual average density, biomass and biodiversity index were 14 664 ind/L (Table 4), 4.903 mg/L (Table 5) and 2.26 (Fig. 4) respectively. Annual average density and biomass reached to the largest at sampling site H (32 909 ind/L) and site 9 (12.176 mg/L) (Fig. 2, Fig. 3) respectively. The density and biological amount of zooplankton varied obviously with seasons. The quantity of species found in autumn was 65 species which is the highest in the four seasons (Table 2). Total of 20 species was recognized as dominance species in the samples collected in one or more than one seasons, however, none of them appeared in the samples through out the whole year. The main dominant species were Tintionnopsis sp., Difflugia sp., Euplotes sp., Keratella sp., Brachionus sp., Polyarthra spp., Bosmina sp., Sinocalanus dorrii and Mesocyclops sp. (Table 3). The total nitrogen, ammonia nirtogen and dissolved oxygen were the significant factors on zooplankton density (Table 6). The evaluation based on the biological diversity index and dominant species indicated clearly that the water quality of Lianhuadang River System was moderately polluted and meso-eutrophic.
