摘要(Abstract)：

为研究农药对海洋微藻的毒性兴奋效应(低剂量刺激生长效应),实验测定了不同时间点、不同剂量草甘膦(Glyphosate)对旋链角毛藻(Chaetoceros curvisetus)和盐生杜氏藻(Dunallelia salina)生长的影响,并使用Log-Logistic修正模型和三维模型对实验结果进行拟合.结果表明,草甘膦对两种海洋微藻均存在不同程度的刺激生长效应,修正的Log-Logistic生长模型和三维模型拟合结果不存在显著性差异,但由于不需编程且能得到更多参数,因此使用Log-Logistic修正模型能够更好地描述草甘膦对藻类的剂量-反应结果.

关键词(KeyWords)： 草甘膦;海洋微藻;刺激生长效应
