Abstract

The environmental preservation areas in the State of Pará provide with the lack of scientific studies on the effects of changes in land

use and the temperature of the earth's surface. In this context, this study aims to analyze the Vegetation Index by Normalized Difference (NDVI) and to verify the behavior of the surface temperature of the land in the Environmental Protection Area (APA) Triunfo do Xingu, in the state of Pará, between the years 2000 and 2019 using a Google Earth Engine (GEE) platform. The results sought that the terrestrial surface in the study area, varied in average of 26.79º C for the year 2000 to 28.90º C for the year 2019. The NDVIs attenuated to represent the vegetation between the 20 years studied indicating changes occurred in an area of ??approximately 828 km² (4.93% of the total area of ??the APA). The results induced that despite the changes identified in the study region, much of the vegetation cover was conserved.
