The work presents results of analysis of changes in ecosystems of the Vychegda River basin (121.4 thousand km 2) during the period of 1984–2015 that were obtained using Landsat images (episodic) and Envisat MODIS time series. Trends of changes in the structure of land fund were shown based on Landsat mosaics made for 1984–1990 and 2010–2015. Main changes of the ecosystems are determined by agricultural development, forestry and high level of swampiness. Early spring data of thermal Landsat channels enable monitoring heat water pollution. Temporal changes in composition of ground surface classes were revealed for 127 key sites in the basins of the first order rivers with an area from 10.8 km 2 (the Chernaya River basin) to 25.6 thousand km 2 (the Vym River basin). Indexes of swampiness were the highest for the basins of the rivers Parch (22.9%) and Tornovka (20.7%); indexes of anthropogenic transformation were maximal in the basin of the rivers Limenda (up to 75%) and Chov'yu (72.8%), while average value was 40.7%. Intact forest arrays exist mainly in the eastern part of the Vychegda basin and cover 37.4% of the territory. Analysis of trends in interannual changes in NDVI from MODIS time series in 2000–2011 revealed areas with opposite directed trends of degradation/recover of vegetation. The most stable values were revealed for indigenous spruce forests.
Keywords: trends in ecosystem changes, Vychegda River, satellite methods, analysis of temporal composites
