Preliminary Studies on Algae from Four Lakes of Baicheng and Songyuan in Jilin Province, China

Algae were sampled from four large lakes of Baicheng and Songyuan in Jilin provi-nce from June to July in 2008.A total of 86 algae taxa were identified,including 5 phyla,7 classes,12 orders,20 families,37 genera,76 species,and 10 varieties.Species composition and habitats in the four large lakes were analyzed.Results showed that most taxa belonged to common species,although some alkaliphilous species were also found,and several indicator species for pollution were found.Based on species composition and distribution in these lakes of Baicheng and Songyuan,the summer community composition of algae might be classified as Bacillariophyta-Chlorophyta type.
