Decorativeness of shrubs at landscaping sites of Krasnoyarsk city

Abstract

One of the key components of environmental protection potential of shrubs is the aesthetic effect in shaping the visual appearance of urban spaces. The variety of shapes, sizes and colors of shrubs allows creating compositions that make the city harmonious and stable at the psycho-emotional level. The “green” aesthetic effect is created due to the biodiversity of plant species (shrubs), their decorative properties (color and texture), volumetricspatial compositions, and the processes of their interaction with the surrounding natural and anthropogenic environment. The objects of the study are shrubs growing in plantings of the city of Krasnoyarsk for various functional purposes, located in 7 districts of the city, maintained by the Municipal Enterprise “Green Construction Management” (MP “GCM”) and the nursery of ornamental plants of the MP “GCM”: glossy cotoneaster, Hungarian lilac, Tatar honeysuckle, two-spined currant, tree-like caragana. The results of the analysis of the decorativeness of the studied shrub species showed that the total score of all the studied shrubs is within 31–47 points, which confirms the high decorativeness of these plant species; the order of decorativeness of shrubs by the total score is from high to low: Tatar honeysuckle – 42.30; Hungarian lilac – 40.79; tree caragana – 35.70; glossy cotoneaster – 35.61; two-spined currant – 34.40. The discrepancies in the values are not significant; each species has its own advantages that must be used when creating volumetric-spatial compositions.
