Wooden plants floristic analysis used in Ussuriysk house territories landscaping in the Primorsky region

The aim of research is to study the floristic composition of woody plants used in landscaping adjacent territories in the city of Ussuriysk, the Primorsky Region. Objectives: to study the features of landscaping adjacent areas (intra-block areas) in an urban environment; to reveal the floristic composition of woody plants used in intra-quarter landscaping; to conduct a geographical analysis of the studied flora; to analyze the life forms of woody plants; to offer promising types of woody plants for indoor greening of the urban environment. The main object of research is woody plants used in landscaping the adjoining territories of Ussuriysk. Research methods: collection of herbarium samples by the route method, determination of the floristic composition, determination of life forms of plants by the method of I.G. Serebryakov (1964). Latin names of plants are given according to the summary "Vascular Plants of the Soviet Far East". In the course of the study, work was carried out to identify systematic groups of plants used in the intra-quarter landscaping of Ussuriysk. 73 species of woody plants from 52 genera and 26 families were registered. The largest is the Rosaceae family - 20 species, 7 families contain 2-5 species, 14 families include 1 species. The leading genus is Rosa - 4 taxa, 15 genera are represented by 2-3 taxa, 36 genera - by only 1 taxon. There is a slight predominance of native plants (60.2 %), woody plants of North American origin prevail among introduced species (44.8 % of the total number of introduced plants). The analysis of the life forms of the studied species in the adjoining territories is represented by trees (44 %), shrubs (43.8 %), semi-shrubs (1.3 %) and lianas (6.8 %). Three species have a changing life form (tree and shrub).
