Abstract

The features of the impact of snow avalanches to the mountain forest landscapes of Ile Alatau are considered. Regularities in the distribution of mountain forest landscapes and forms of avalanche activity have been studied. The quantitative assessment of the impact of avalanches on the mountain forest landscapes in Ile Alatau was carried out using remote sensing data and GIS technologies. Based on the processed data of satellite images for determination of mountain forest landscapes, the areas of forests and avalanche swath were calculated for river basins and high-altitude zones of the northern slope of the ridge. The shares of avalanche swath from the total forest area were defined. It has been determined that avalanches significantly reduce the area of mountain forests.
