摘　　要：水生植物的克藻效应受到多种环境因子的影响。利用响应曲面法,对影响沉水植物蓖齿眼子菜对铜绿微囊藻克藻效应的3个环境因子进行实验研究。通过对曲面模型分析,得出蓖齿眼子菜对铜绿微囊藻的藻细胞个数的相对抑制率在温度、光照强度、全盐量3个环境因子分别为24℃、2 891 lx、4 407 mg/L时达到最大值。曲面模型经过方差分析,具有显著性高、相关系数高、模型拟合度较好等特点。The algae-allelopathic effects of submerged macrophytes could be affected by many environmental factors.In this paper,response surface methodology（RSM） was used to optimize three environmental factors（temperature,light intensity and total dissolved solids） of allelopathic effects of Potamogeton pectinatus against Microcystis aeruginosa.The response surface plots showed that the optimum ranges of the relatively inhibitory rate of algal cell number lied in 24 ℃,2 891 lx and total salt content of 4 407 mg/L.The significance level of the RSM model was less than 0.000 1 and the correlation coefficient was 0.995 4,which indicating the model was satisfactory and accurate.
