通过分析不同浓度铜、锌离子对中肋骨条藻生长和生理的影响，探讨中肋骨条藻作为指示生物反映河口海区环境中铜、锌污染因子的变化情况的可能性。研究发现，随着铜离子浓度的增加，中肋骨条藻的生长受到明显的抑制；而锌离子浓度增加时，中肋骨条藻的生长先被促进后受抑制。中肋骨条藻中POD，CAT和GSH-px的变化趋势与中肋骨条藻的生长曲线相一致，能够反映藻类生长状况，其中POD的变化更明显，因而可以中肋骨条藻作为指示生物，POD作为指示因子，反映河口区铜、锌离子的污染状况。

By analyzing the effects of different concentrations of copper and zinc ions on the growth of skeletonema costatum and physiology,this paper explored the possibility of skeletone-ma costatum as a bio-indicator to reflect the change of zinc and copper pollution in the environ-ment of estuary area.The results showed that with the increase of copper ion concentration,al-gae growth was significantly inhibited;while with the increase of zinc ion concentration,the growth of s.costatum was first promoted and then suppressed.Variation of POD,CAT and GSH-px of skeletonema costatum and the growth of s.costatum were consistent,which could re-flect the growing condition of algae.The change of POD was more obvious.Thereby Skeletone-ma costatum could be taken as a bio-indicator and POD as a pollution indicator to reflect the con-dition of copper and zinc ions in estuary.
