摘要
为研究湖泊生态修复对浮游动物群落结构的影响,该文于2010年1-12月份对惠州西湖未修复的子湖-平湖及已实施生态修复后的子湖-元妙观湖、南南湖的浮游甲壳动物群落结构进行了调查。结果表明:龟状笔纹溞、卵型盘肠溞、矩形尖额溞和右突新镖水蚤仅出现在修复后的元妙观湖与南南湖,而颈沟基和溞与平直溞仅在平湖中检出;元妙观湖和南南湖浮游甲壳动物种属数、丰度及多样性指数均高于平湖。冗余分析结果表明:哲水蚤、剑水蚤和枝角类丰度与透明度呈正相关,哲水蚤密度与营养盐呈负相关。研究显示,湖泊生态修复对浮游动物群落结构有重要的影响。
In order to study the effects of ecological restoration on the community structures of planktonic crustaceans, we investigated the planktonic crustaceans in two ecologically restored areas and an un-restored area of Huizhou West Lake monthly from January to December in 2010. Graptolebris testudinaria, Chydorus ovalis, Alona rectangular and Neodiaptomus schmackeri were only found in restored areas, and we found Bosminopsis deitersi and Pleuroxus sp. only in un-restored area. The abundance and the diversity index of the planktonic crustaceans in restored areas were higher than in un-restored area. Redundancy analysis showed that the abundance of Cladocera, Cyclopoida and Calanoida had significantly positive correlations with secchi depth, and the density of Calanoida had significantly negative correlations with nutrient levels, This study indicates that the ecological restoration has a significant effect on the community structures of planktonic crustaceans of lakes.
