摘　　要：运用实验生态学和生物化学的方法研究了多环芳烃(PAHs)—蒽胁迫对米氏凯伦藻生长的影响及抗氧化酶(SOD、CAT、POD)活性的影响.结果表明:随着蒽质量浓度的增加,对米氏凯伦藻生长的抑制作用增强,且有较强的剂量—效应关系;而抗氧化酶均出现了不同程度的应激活性,以减少蒽胁迫对藻细胞自身的伤害.说明抗氧化酶在一定的污染物浓度范围内具有防御保护作用,且作用大小不同.In this paper, effects of polycyclic anthracene on growth and activities of antioxises of Krenia mikimo- toi Hansen were studied through experimental ecology and biochemical methods. The results indicated that, the in- hibition on growth of microalgae was enhanced with the increasing of concentration of anthracene, which presented a good concentration-dependant relationship; and the antioxidase activities were enhanced in various degree to allevi- ate the oxidative damage from anthracene. Therefore, it suggested that antioxidase had a positive protective effect within a certain limit, and the effect had notable difference
