| 摘 要： | 本文研究了北京翠湖湿地公园夏、秋季水华优势藻血红裸藻(Euglena sanguinea)从水华发生到衰亡过程的细胞密度、形态特征及其与环境因子的关系.结果发现,2016年8月下旬至9月中旬血红裸藻密度稳定增加,9月20日藻密度达到峰值5.13×106cells/L;9月下旬至11月底藻密度显著下降;血红裸藻在衰亡过程中呈现细胞形态由大变小、由细长变为圆形,细胞颜色由深变浅,运动速率由快变慢的趋势,衰亡后形成具透明胶被孢子的休眠体;血红裸藻群落生长的主控因子为水温和p H,其适宜的环境阈值范围为水温23~27℃,p H 7.3~8.0;其受光照强度影响存在分层现象,弱光强区域藻密度相对较低;血红裸藻的衰亡过程与铵态氮浓度呈显著正相关,低浓度时加速衰亡;与总氮浓度呈负相关,衰亡后总氮浓度显著升高;受总磷浓度影响相对较小,与溶解氧浓度无显著相关关系.
