Abstract
An important resource of the Uzhgorod district and its fourteen territorial communities is the plant cover, which is characterized by a significant phytocenotic diversity. The landscapes of the Uzhgorod district have been undergone significant anthropogenic changes, especially in the flat part, where agricultural lands with mainly arable land and pastures. Numerous vegetation indices are used for the monitoring of the vegetation cover condition using remote sensing data, among which NBR is the normalized burn ratio index. Such an index is an informative quantitative indicator of the state of vegetation in general and as a result of the impact of fires in particular. To calculate and compare the NBR index, images with minimum cloud cover for August-September 2023 were used. The selected period is due to the temperature peak and seasonal burning of dry vegetation. Also, at the end of summer and beginning of autumn, the harvesting of cereals and other agricultural crops begins, as a result of which there is a significant decrease in vegetation cover, which affects the reflectivity of the surface and the value of the NBR index. The values of community areas with negative values of the NBR index and their correlation with the total area and population were analyzed.
