A total of 155 taxa of diatoms, including 2 classes, 6 orders,9 families 26 genera,113 species,39 varieties and 3 forms, were identified. Of these taxa, 2 species,2 varieties,and 1 form are first reported in China. Diatom communities, species composition and habitat, diatoms in Qixing River Wetland were analyzed. It shows that most taxa belong to common species, and some acidophil species such as Eunotia pectinalis var. ventralis (Ehr.) Hust., Tabellaria flocculosa (Roth) Kütz., Gomphonema augur Ehr., Navicula subtilissima Cl. and a few alkalibiontic species were also found.
