Аннотация: The purpose of this study is to find a relationship between changes in spectral characteristics (MODIS/Terra) of mountain forests and the altitude at which they grow. In the study area, which is located in the West Sayan Mountains (in South Siberia), the types of forest ecosystems change markedly with altitude. The study uses the dПоказать полностьюata of the MODIS-NPP model intended for the evaluation of global net production. Results of the study show that the best approach to dividing mountain forests into different types is to use 8-day composites of satellite data collected at the beginning of the growing season (April-May). This is the time when the most significant differences are recorded between vegetation indices, including Normalized Difference Vegetation Index (NDVI), LAI, and EVI of the mountain forests growing in different altitudinal zones. © Springer International Publishing Switzerland 2015.
