吉林省白城、松原地区部分湖泡藻类植物的初步研究

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

2008年6～7月间对吉林省白城及松原地区4个大型湖泡中的藻类植物进行了调查,共鉴定藻类植物86个分类单位,包括76种10变种,分别隶属于5门7纲12目20科37属,初步分析了白城及松原地区4个大型湖泡中藻类植物群落的种类组成及生态类型,在该区域出现的大部分藻类属于普生种类,同时出现了一些碱水种类,此外还有少量的污染指示种出现。根据种类组成及分布初步推断,夏季白城、松原地区部分湖泡的藻类植物群落组成主要为硅藻—绿藻类型。

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.
