The paper presents the results of a comprehensive analysis of the species composition of Cheboksary. The analysis of the dendroflora of the urban environment was carried out according to 3 indicators: the territory of woody plants, the occurrence of woody plant species in landscaping, the structure of the landscaping system. The arboreal vegetation of Cheboksary is represented by 73 species belonging to 43 genera and 20 families. The predominant part of the dendroflora is represented by the covered-seeded plants (86,3%), the gymnosperms 13,7%. In the dendroflora of green areas of the city, the most widely represented families are Rosaceae, Pinaceae, Salicaceae (48%). The analysis of the species composition of woody plants showed that in the functional and economic zones of Cheboksary plantings of general use are represented by 65 species, plantings of limited use 52 species, plantings along the streets and main roads 50 species. The analysis of the species composition of woody plants depending on the share of their participation in landscaping revealed that the greatest number of woody plants is used with low (51 species) and medium (50 species) share. The analysis of the degree of participation of woody plants in landscaping in the four identified functional and economic zones of Cheboksary found that the greatest number of taxa prevail with an average participation in the central zone (37 species), the coastal and suburban zones (36 species). The largest number of species of woody plants grow in the green areas of the central functional and economic zone, where the landscaping involved 66 species, the smallest number grow in the green areas of the industrial area (36 species).
