Abstract
The article considers the features of accumulation of snow reserves under the influence of forest stands of birch hanging openwork-blown structure in the plakor-plain (0-1°), slope-hollow (1-3°) and slope-ravine (3-5°) types of agroforestry landscapes.
Introduction. One of the most important climatic factors against the background of regional climate change is the snow cover, which contains huge reserves of moisture and makes a great contribution to obtaining high yields. Forest plantations contribute to the most productive accumulation of snow and its uniform distribution.
Object. The object of research is the snow cover.
Materials and methods. The research was carried out on the experimental field of the Ulyanovsk Research Institute in the system of the erosion control complex of the Experimental Station “Novonikulinskaya” of the Tsilninsky district of the Ulyanovsk region. The height of snow and its density were measured on the eve of snowmelt: the density of snow cover was determined by a weight snow meter – VS43, height – by a portable metal rail.
Results and conclusions. Snow deposition in the mountain-plain type of agricultural landscape accumulates within the limits of 41.4 cm and 31.0 cm, on the slope–hollow – 36.9 and 34.0 cm, in the slope–ravine – 34.2 and 28.7 cm. The largest amount of spring moisture reserves due to snow melting in the inter-lane space is formed on the plateau-plain type of agricultural landscape. At a distance of 50 m from the windward and windward forest strips, this indicator was 109.3 and 91.5 mm. With the approach to the central part of the field (260 m), the provision of moisture due to snow decreased to 77.3 mm. A similar dependence can be traced on the slope-hollow and slope-ravine types of the agricultural landscape, but with a much smaller predicted water supply in the snow cover.
