| 摘 要： | 异龙湖是云南省第九大湖泊,属典型的高原浅水湖泊.为了解该湖不同湖区浮游植物群落特征,于2013年8月至2014年7月逐月对该湖西区、东区和沉水植被恢复示范区浮游植物及环境因子进行调查分析.结果表明,不同湖区生境条件具有空间异质性,示范区和西区水体总氮(TN)、总磷(TP)、氨氮(NH_4~+-N)、五日生化需氧量(BOD5)、透明度(SD)、浊度(Turb.)和电导率(EC)等理化指标无显著差异,而与东区有显著差异性(P 0. 05). 3个湖区浮游植物密度均以蓝藻门所占比重最大,浮游植物优势类群不同,西区细小平裂藻(Merismopedia tenuissima)优势度最高,东区拉氏拟柱孢藻(Cylindrospermopsis raciborskii)和湖生伪鱼腥藻(Pseudanabaena limntica)优势度最高,示范区细小平裂藻和拟项圈藻(Anabaenopsis sp.)优势度最高.通过主坐标分析(PCo A)对3个湖区浮游植物群落β多样性进行比较发现,西区和示范区群落结构较为相似,而与东区具有极显著的差异(P 0. 01).运用冗余分析(RDA)探讨异龙湖浮游植物群落特征与环境因子的关系,结果表明,TN、TP、BOD5和SD是影响异龙湖浮游植物群落分布的主要环境因子,NH_4~+-N、EC、高锰酸盐指数和p H值对浮游植物群落也有一定的影响.
