摘　　要：在实验室模拟条件下,研究了温度、光照、盐度和营养盐对大溪地金藻生长繁殖的影响,结果表明:大溪地金藻适宜温度为10～35℃,最适温度为20～30℃;适宜照度为1000～7000lx,最适照度为3000～6000lx;适宜盐度6 5～39 5,最适盐度为19 5～26 0。N、P单因子的优水平分别为N-1mg/L、P-0 1mg/L,Fe单因子作用不明显,N、P、Fe交互作用的优水平为N-1mg/L、P-1mg/L、Fe-0 1mg/L。The effect of temperature, illumination intensity, salinity and nutrients on growth and reproduction of Isochrysis galbana was studied under the experimental conditions. It was found that the adaptive water temperature ranged between 10℃ and 35℃ with the optimal temperature of 20～30℃. The optimal illumination intensity was 4000～6000 lx with adaptive value of 1000 ～ 7000 lx. The range of adaptive salinity was 6.5～39.5, and the optimal 19.5～26.0. The alga grew best under 1 mg N/L,0.1 P mg/L and 1 mg N /L, 1 mg P /L, and 0.1mg Fe /L in the culture. There was no significant effect in Fe ion concentration.
