Аннотация:The current ecological state and landscape dynamics of the protected areas of the Northern Caucasus as a result of nature processer’s activity and anthropogenic impact are revealed on the basis of interpretation of multi-temporal remote sensing data, long-term field landscape mapping and repeated observations on model sites. The national park “Prielbrusie” and Teberda Nature Reserve, one of the most popular areas of the mountain recreation in Russia, and their surroundings are chosen as the main study objects. These protected areas are characterized by high biological and landscape diversity, rich nature resources, historical and culture heritage and must play significant role in the sustainable development of the region. But during the last decades the degradation of landscapes as result of nature processes activity firstly of catastrophic snow avalanches and debris flows including outburst of periglacial Lake Bashkara and formation of powerful debris flow reflecting climatic fluctuations, and of social-economic transformation has been identified. The reduction in area and diversity of forests, the changes of glacier-nival, alpine and subalpine meadow and meadow-steppe landscapes, the increase of degraded pasture lands, the intensification of scree and erosion processes, the reduction of aesthetic properties of nature and recreation complexes are some negative consequences of anthropogenic and nature hazards effect, that lead to the decrease of ecosystem services. Large-scale maps of landscape dynamics on the model sites of the protected areas are compiled and some recommendations on landscape planning of the territory, including correct functional zoning of national park and further improving of ecological tourism and recreation are suggested.
