This article is devoted to development of a method for assessing NDVI dynamics in northern territories and analysis of NDVI dynamics of vegetation on the territory of the Krasnoyarsk region using MODIS/Terra satellite data for the period (2000-2020). Spatial distribution map of average annual vegetation index NDVI has been made, indicating five latitudinal sections through the territory of the Krasnoyarsk region: the coordinates (latitude from 52˚ N to 76˚ N, longitude from 91˚ E to 95˚ E). Latitudinal variability of NDVI index for 20 years of measurements has been studied. Heterogeneity of long-term dynamics of vegetation has been discovered depending on the latitude of the studied territories. Efficiency of the suggested method for identifying long-term NDVI trends has been shown. A positive NDVI response of the vegetation cover of northern territories of the Krasnoyarsk region to climatic changes over the last 5 years has been revealed.
