摘　　要：本文研究了5种水产药物对扁藻种群生长的影响.结果表明,硫酸铜、高锰酸钾、孔雀石绿、敌百虫和甲醛对扁藻96h的EC50依次为61.16、49.22、72.97μg/dm3和7.58、0.70mg/dm3.硫酸铜、高锰酸钾、孔雀石绿、敌百虫和甲醛对扁藻生长的安全浓度分别是18.12、12.14、23.26μg/dm3和2.25、0.24mg/dm3.结果还表明,这5种常用水产药物中,以高锰酸钾对扁藻生长的抑制作用最大,敌百虫对扁藻生长的抑制作用最小.The effects of 5 aquatic medicines to Platymonas subcordiformis were studied in this paper. The results showed that, the 96h EC5o of CuSO4, KMnO4, malachite green, trichlorfon and formalin to P. subcordiformis were 61.16μg/dm^3, 49.22μg/dm^3, 72. 97μg/dm^3, 7.58mg/dm^3 and 0. 70mg/dm^3 respectively. The safe concentration of CuSO4, KMnO4 ,malachite green, trichlorfon and formalin to P. subcordiformis were 18. 12μg/dm^3, 12. 14μg/dm^3, 23. 26μg/dm^3, 2. 25mg/dm^3 and 0. 24mg/dm^3. It also indicated that, among these 5 aquatic medicines, KMnO4 was the strongest inhibitor to the growth of P. subcordiformis, trichlorfon was the mildest.
