%X Aquarium microcosms were used to study the effects of nitrogen source and aeration mode on the growth and species changes of algae in freshwater.Nitrate nitrogen(NO3--N) and ammonia nitrogen(NH4+-N) were used as nitrogen sources.For each nitrogen source,four modes of aeration were selected, including control,continuous aeration,aeration during the day,and aeration at night.In the early stage of the experiment,algae in the NH4+-N treatment experiment grew well.In the later stage,algae in the NO3--N treatment experiment grew better.For different aeration modes,continuous aeration show varied effects on algae growth in the two nitrogen source treatments.Day-only aeration had little effect on algae growth.Night-only aeration inhibited algae growth considerably.In NH4+-N treatments,cyanophyta became dominant species easily.In contrast,chlorophyta dominated in NO3--N treatments.
