| 【目的】以两种生物浮床的养殖池塘为研究对象，探究水体中浮游动物的多样性及其与水质因子
的关联度。【方法】定期监测设置水葫芦浮床和水花生浮床的黄颡鱼养殖塘中浮游动物的种群组成及主要水质
因子，比较两种生物浮床对浮游动物多样性的影响；利用灰色关联分析法分析 WT、DO、pH、NH3-N、COD
等 10 个水质理化因子与浮游动物 Shannon-Wiener 多样性指数（H）和 Pielou 均匀度指数（J）的关联性。【结果】
研究水域中水葫芦浮床塘的浮游动物丰度和多样性水平均高于水花生浮床塘，且养殖周期内水质较稳定；浮游
动物优势种群为轮虫。水质因子中，pH 值是影响 H 及 J 的第一因子，关联度分别为 0.863、0.797 和 0.901、0.825，
其次为 WT 和 DO；主要水质因子对 H 和 J 的影响力从大到小依次为 pH ﹥ WT ﹥ DO ﹥ COD ﹥ SD ﹥ BOD5 ﹥
NH3-N ﹥ TN ﹥ TP ﹥ NO2-N。【结论】在众多水质因子中，pH 值是影响浮游动物多样性的首要关键因子，其
次为 WT 和 DO；水葫芦浮床较水花生浮床能更好地调控浮游动物的种群结构。 |

| 【Objective】Taking the culture ponds with two kinds of biological floating beds as the research object,
the diversity of zooplankton in pond and its correlation with water quality factors were studied.【Method】The species
Vcomposition of zooplankton and main water quality factors in the ponds of Pelteobagrus fulvidraco cultured in two kinds of
biological floating beds were monitored regularly and the effects of water hyacinth floating bed and alligator weed floating
bed on the diversity of zooplankton were compared. Grey Relational Analysis was used to analyze the correlation of 10
physicochemical factors of water, such as WT, DO, pH, NH3-N,COD and the Shannon-Wiener diversity index (H) and Pielou evenness index (J) of zooplankton.【Result】The results showed that the abundance and diversity of zooplankton in
water hyacinth floating bed ponds were higher than those in alligator weed floating bed ponds, and the water quality of water
hyacinth floating bed ponds was stable during the culture cycle. The dominant species zooplankton was rotifer. Among the water
quality factors, the pH value was the first factor affecting H and J, with the correlation degree of 0.863, 0.797 and 0.901, 0.825,
respectively, followed by WT and DO. The influence of main water quality factors on H and J ranked as follows: pH > WT > DO
> COD > SD > BOD5 > NH3-N > TN > TP > NO2-N.【Conclusion】Among the many water quality factors, pH is the primary
key factor affecting the diversity of zooplankton, followed by WT and DO. The water hyacinth floating bed can better regulate
the population structure of zooplankton than the alligator weed floating bed. |
