The study analyzed the dynamics of the NDVI vegetation cover of the M. Gafuri Park in Ufa. For this purpose, the Landsat satellite images for 1997, 2014 and 2023 were used, which determined the NDVI of the vegetation cover of the studied park. The images were processed using the ArcGIS 10.5 software. The NDVI vegetation index on the resulting thematic map is grouped into 7 classes with a gradation from 0.0 to 0.7. The results indicate an increase in NDVI in several classes during the period under review in the study area. In the picture from 1997 Most of the forest park's territory is characterized by sixth (49.1%), seventh (33.7%) and fifth (10.7%) classes. The 2014 Landsat image shows a decrease in the NDVI value in terms of vegetation cover. The changes in grades 3-7 are significant in terms of area. As of 2023, Class 4 dominates in the park – 47.9%. The decrease in photosynthetic activity of the studied area reflects large area transitions from class 6-7 to lower ones. This fact can be attributed to a decrease in forestry completeness (the degree of crown closure). A decrease of 2 classes or more is associated with the construction of landscaping facilities. Over the 26-year period, there have been changes in all classes of the NDVI index.
