Abstract: 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.
