Снежный покров и формирование древесной растительности в зоне аэротехногенного воздействия ОАО «Североникель»

Abstract

In the area of plant emissions “Severonikel” (Monchegorsk) on 6 sample plots (5, 7, 11, 19, 29 and 45 km from the emission source), with varying degrees of degradation phytocenoses were investigated features of snow cover at the beginning of a snowmelt period: height, density and distribution pattern of the snowpack. Were brought data a few years old about height and thickness of stand. Was found that density of snow more on open treeless areas in the impact zone. Was revealed that snow has a significant impact on the vegetation cover, because of the melting of pollutants contained in it due to man-made pollution contribute to the thinning out of the tree layer.
