NDVI Changes as an Indicator of the Dynamics of the Ecological State of Landscapes (on the Example of the Eastern Part of the Polessie Province)

Abstract

The aim of the research is to study the dynamics of NDVI as an indicator of changes in the state of deciduous-forest landscapes at the regional and local level. As an operational territorial unit, a selection of the type of natural landscape was used. NDVI values are from MOD13Q1. The changes in NDVI in 2000-2018 are considered in the eastern part of the Polessie province (southeast of Belarus). The features of NDVI dynamics in test areas that differ in the pattern of anthropogenic transformations are studied. The regional trends in the dynamics of NDVI are revealed. A significant part (47.7 %) of the region's territory is characterized by an increase in average NDVI values. The largest increase in NDVI occurred in floodplain landscapes. Locally (4.4 %), plots were identified where a decrease in NDVI is observed, probably due to anthropogenic transformations of landscapes.
