- Аннотация: The chapter focuses on landscape structure of paragenetic geosystems shaped by snow avalanches and debris flows with main attention to the stopping zone. The research was performed in the mountains of Western and Central Caucasus based on the long-term field observations, landscape mapping, interpretation of remote sensing data and phytoindication. Landscape structure in the zones of natural processes activity is polystructural and depends on the type of processes, their frequency and the internal features of the affected landscapes. Wet avalanches are followed by the strongest changes. A single influence, especially accompanied by the airwave, often results in relatively rapid recover of zonal vegetation. As a result of prolonged avalanche releases, nature complexes belonging to neighbouring zonal types or subtypes may develop. The impact zones are characterised by emergence of a series of complexes being indicative of avalanche frequency and duration. We distinguished several types of landscape patterns indicating the avalanche activity. Intensification of landscape changes in the late twentieth and the early twenty first century due to the large avalanche and debris flow releases was detected.
