摘　　要：研究了赤潮异弯藻、亚历山大藻和中肋骨条藻种群增长的特征及其对CO2加富的响应变化。结果表明:3种赤潮藻的生长曲线可用逻辑斯谛增长模型拟合。CO2加富对3种藻生长过程中进入指数生长期和静止期的时间、所达到的种群最大细胞数均有影响,使3种藻进入指数生长期和静止期的时间缩短,但所达到的种群最大细胞数明显提高。The growth characteristics and responses of Heterosigma akashiwo, Alexandrium tamarense and Skeletonema costatum under CO2 enrichment were studied. The results showed that the growth curves of three species of microalgae could be predicted by the Logistic growth model. Under CO2 enrichment, the population growth of three species of red-tide microalgae showed the similar regulation. The time of entering exponential phase and stationary phase of growth could be shortened, and the maximum population density could be increased obviously.
