摘　　要：[ Objective] This study aimed to investigate the effects of 1-naphthol on primary productivity in aquatic ecosystems. [ Method] The effects of 1-naphthol on biomass, chlorophyll a content, malondialdehyde （MDA） content and soluble protein content of Chlorella vulgaris were investigated. [ Result] 1-Naphthol could significantly inhibit the growth of Chlorella vulgaris. On the 7^th d, the biomass of Chlorella vulgaris exposed to 1.0, 3.0, 6.0, 12.0 and 18.0 mg/L 1-naphthol was 60.26%, 48.15%, 41.32%, 28.59% and 27.10% of that in control respectively, exhibiting a significant dose-response relationship. Chlorella vulgaris was exposed to different concentrations of 1-naphthol （0, 1,5 and 10 mg/L） for 7 d ; with the increase of 1-naphthol concentration, chlorophyll a content of Ch/orella vulgaris was reduced, MDA content increased gradually, soluble protein content increased first and then declined. [ Conclusion] According to the experimental results, 1-naphthol can significantly inhibit the growth of Chlorella vulgaris, thus reducing primary productivity in aquatic ecosystems.[ Objective] This study aimed to investigate the effects of 1-naphthol on primary productivity in aquatic ecosystems.
