摘　　要：采用室内模拟培养试验方法,研究了酰胺类除草剂丁草胺对杜氏盐藻(Dunaliella salina)生长和生理生化的影响。结果表明,低浓度的丁草胺对杜氏盐藻生长速率有促进作用,而高浓度的丁草胺对杜氏盐藻生长速率有显著的抑制作用,且随着浓度的加大,杜氏盐藻生长速率逐渐降低。丁草胺对杜氏盐藻藻细胞的光合色素含量、可溶性蛋白、超氧化物歧化酶(SOD)和过氧化物酶(POD)活性等也有影响。In this paper, effect of acetanilide herbicides butachlor on Phsiological and Biochemical Characteristics of Microalgae Dunaliella salina was studied in the laboratory. The results showed that the growth of Dunaliella salina was stimulated under low concentration of butachlor culture medium and significantly inhibited under high concentration of butachlor culture medium. Butachor also had effects on the activities of photosynthetic pigment, protein content, superoxide dismutase （SOD） and peroxidase （POD） ofDunaliella salina.
