摘　　要：为探究北京市五大水系的水生生物多样性,采用野外调查和室内观察相结合的方法,于2016—2019年对北京市潮白河、大清河、永定河、北运河和蓟运河五大水系中绿藻门盘星藻属Pediastrum Myren的种类形态与分类学进行了研究。结果表明:共鉴定出绿藻门盘星藻属的单角盘星藻、斯氏盘星藻、卵形盘星藻、具孔盘星藻、二角盘星藻、双射盘星藻、缢缩盘星藻、整齐盘星藻、短棘盘星藻和四角盘星藻共10个种,单角盘星藻具孔变种、单角盘星藻颗粒变种、单角盘星藻对突变种、单角盘星藻粒刺变种、二角盘星藻纤细变种、二角盘星藻圆形变种、二角盘星藻山西变种、二角盘星藻网状变种、二角盘星藻真实变种、二角盘星藻大孔变种、二角盘星藻皱褶变种、短棘盘星藻长角变种、短棘盘星藻短角变种、短棘盘星藻镊尖变种、短棘盘星藻颗粒变种、短棘盘星藻穿孔变种、短棘盘星藻波缘变种、整齐盘星藻小齿变种、整齐盘星藻具孔变种和四角盘星藻四齿变种共计20个变种;从外层细胞的形态和角突数、是否有穿孔、细胞壁上是否有颗粒和棘刺等方面描述了盘星藻属各种和亚种的形态特征,并列出其分布水体,建立了原色图谱和分类检索表。研究表明,北京市盘星藻属有10个种20个变种,其中有20个原种或变种是北京市新记录的盘星藻种类。In order to elucidate the aquatic biodiversity of five major water systems in Beijing,morphology and classification of the genus Pediastrum in Chlorophyta phylum were studied in 53 sampling sites in the five major water systems in Beijing area from 2016 to 2019 by means of field investigation and indoor observation.The results showed that there were 10 species(P.simplex,P.sturmii,P.ovatum,P.clathratum,P.duplex,P.biradiatum,P.constrictum,P.integrum,P.boryanum and P.tetras)and 20 varieties(P.simplex var.duodenarium,P.simplex var.granulatum,P.simplex var.biwaense,P.simplex var.echinulatum,P.duplex var.gracillimum,P.duplex var.rotundatum,P.duplex var.shanxiensis,P.duplex var.reticulatum,P.duplex var.genuinun,P.duplex var.clathratum,P.duplex var.rugulosum,P.boryanum var.longicorne,P.boryanum var.brevicorne,P.boryanum var.forcipatum,P.boryanum var.granulatum,P.boryanum var.perforatum,P.boryanum var.undulatum,P.integrum var.perforatum,P.integrum var.braunianum,and P.tetras var.tetraodon)in water systems in Beijing area.The morphological characteristics were described and the distribution in various species and subspecies of Pediastrum was listed,from a point of view of the number and morphology of the outer layer cells,whether there are perforations,or particles and thorns on the cell wall,in the water bodies.The primary color map and classification key table were established.It is concluded that there were 10 species and 20 varieties of genus Pediastrum,including 20 original species or varieties were newly recorded in Beijing area,which provides a reference for the protection and classification of green alga diversity in Beijing.
