摘　　要：选用铜绿微囊藻（Microcystis aeruginosa）和脆杆藻（Fragilaria sp．）为试验材料，在不同锌离子浓度下对2类微藻的增殖影响进行研究分析。藻类增长潜力（AGP）实验结果显示，在Zn^2＋浓度为0．02～1．00μg／L的液体培养基中，铜绿微囊藻的生长增殖快，Zn^2＋浓度达到100．00μg／L时，受到明显抑制。Zn^2＋浓度在0．02μg／L时，脆杆藻的生长繁殖快，Zn^2＋浓度〉0．10μg／L后，则受到不同程度的抑制。Microcystis aeruginosa and Fragilaria sp. were cultured to study the effects of Zinc at different concentrations on their cell multiplications. Algal growth potential test indicated that Microcystis aeruginosa multiplied quickly with Zn^2＋ concentration ranging between 0.02 μg/L and 1.00 μg/L and got remarkably inhibited with Zn^2＋ concentration reaching 100.00 μg/L. Fragilaria sp. multiplied quickly with Zn^2＋ concentration at 0.02 μg/L and got inhibited in various degrees with Zn^2＋ concentration above 0.10 μg/L.
