,平均生物量為 <img src="/qkimages/ankx/ankx202508/ankx20250819-2-l.jpg" with="75px" style="vertical-align: middle;"> ,優(yōu)勢類群隸屬于輪蟲和原生動物。浮游動物群落以小型浮游動物(尤其是輪蟲)為主,其密度和生物量隨養(yǎng)殖時間的延長而增加,多樣性指數(shù)具有相對穩(wěn)定的特點。層次聚類和非度量多維尺度分析(NMDS)結(jié)果表明,不同月份浮游動物群落結(jié)構(gòu)具有顯著差異。冗余分析和變差分解分析結(jié)果表明,浮游動物群落結(jié)構(gòu)主要受8種水環(huán)境因子的影響,包括溶解氧含量、pH、Chla含量 <img src="/qkimages/ankx/ankx202508/ankx20250819-3-l.jpg" with="67px" style="vertical-align: middle;"> 、磷酸鹽含量、硝態(tài)氮含量、亞硝態(tài)氮含量和電導(dǎo)率。此外,浮游動物群落以淹青完成為時間節(jié)點出現(xiàn)明顯變化,淹青在一定程度上改變了養(yǎng)殖環(huán)境,從而影響了浮游動物豐度。-龍源期刊網(wǎng)" />
