摘要
2016—2017年对射阳湖开展浮游动物群落结构和水质指标逐月监测。结果表明,射阳湖共鉴定出浮游动物61种,其中原生动物、轮虫、枝角类和桡足类分别为25种、24种、7种和5种。浮游动物种类数呈现春夏季多于秋冬季的变化趋势。浮游动物优势种数量较多、分布广,群落结构相对复杂且稳定。运用Shannon-Wiener指数、均匀度指数和B/T指数对射阳湖水质作评价,结果表明,该湖处于轻度—中度污染状态,生物学指标评价法与常规水质评价结果一致。浮游动物群落结构与水质指标相关性分析表明,水温、透明度、Chl-a和DO是影响射阳湖浮游动物群落结构的主要水质指标。
In this s tudy,zooplankton community structure and the water quality indexes were investigated monthly in Sheyang Lake during the year from 2016 to 2017.The results showed that 61 species of zooplankton were detected,including 25 species of protozoa,24 species of rotifers,7 species of cladocerans and 5 species of copepods.The numbers of zooplankton species in spring and summer were larger than that in autumn and winter.The dominant species were of much in quantity and wide in distribution,and the community structure was complex and stable.The water quality was mildly to moderately contaminated evaluated by Shannon-Wiener biodiversity index,Pielou evenness index and B/T index,which were consistent with the results from conventional water quality assessment.Water temperature,transparency,Chl-a and DO were the main water quality indexes influencing the zooplankton community structure in Sheyang Lake by correlation analysis of zooplankton community and water quality.
