摘　　要：[目的]研究铜绿微囊藻越冬与复苏的生长条件。[方法]采用玻瓶法进行藻类生长潜力试验。测定铜绿微囊藻藻液的吸光度、培养液中总氮(TN)和总磷(TP)含量,绘制藻类生长曲线,TN和TP的变化曲线,从而探讨其生长与繁殖规律。[结果]铜绿微囊藻的生长需要较高的温度,低温对铜绿微囊藻的生长不利。在冬季,温度变化对指数生长期的铜绿微囊藻生长影响不大,而外界不利条件对处于稳定期的铜绿微囊藻影响较小。在春天,当温度升高时,处于休眠期的铜绿微囊藻开始复苏。此外,充足的营养盐有利于铜绿微囊藻的越冬与复苏。[结论]获得铜绿微囊藻越冬与复苏的生长条件,为治理水体富营养化提供一定的理论指导。[Objective] The research aimed to study the growth condition of Microcystis Aeruginosa in the overwintering and recovery periods.[Method] The glass bottle method was used to do the algal growth potential test（AGP test）.The absorbance of algae liquid,the contents of total nitrogen（TN） and total phosphorus（TP） in the culture liquid were measured,which were used to draw the growth curve of algae,the variation curves of TN and TP.Then,the growth and propagation rules of Microcystis Aeruginosa were discussed.[Result] The growth of Microcystis Aeruginosa needed the higher temperature,and the low temperature wasn＇t favorable for the growth of Microcystis Aeruginosa.In winter,the temperature variation had no influence on the growth of Microcystis Aeruginosa in the exponential growth period,and the unfavorable conditions in the environment had the small influence on Microcystis Aeruginosa in the stable period.In spring,when the temperature rose,Microcystis Aeruginosa in the dormant period started to revive.In addition,the sufficient nutrient salt was favorable for the overwintering and recovery of Microcystis Aeruginosa.[Conclusion] The growth conditions of Microcystis Aeruginosa in the overwintering and recovery periods were gained,which provided the certain theory guidance for the treatment of water body eutrophication.
