The effect of surface temperature on the state of the vegetation in the forest of Polylepis spp and to relate it is the objective of this research. As methodology 9 satellite images of the Landsat 8 OLI / TIRS Sensor were used, evaluated using remote sensing, applying Pearson r correlation and statistical t student hypothesis. The following results were obtained: the relationships during the 9 months of the year 2018 - - 2019 between LST - NDVI r = 0.11, t = 0.29; LST - NDWI r = -0.43, t = 1.27; LST - SAVI r = 0.13, t = 0.34 and LST - MSI r = 0.56, t = 1.77; the average ratio of 9 images classified in Jenks Natural Breaks values ​​between LST - NDVI r = 0.99, t = 47.12; LST - NDWI r = -0.98, t = 28.93; LST - SAVI r = -0.99, t = 65.39 and LST - MSI r = 0.99, t = 30.39; and the effect of “TVX” for NDVI (East: -0.0778 / 0.0549; West: 0.6434 / -0.0120), NDWI (West: -0.6128 / -0.0463; East: 0.3057 / 0.0474), SAVI (West: 0.4089 / 0.0232; East: -0.0073 / -0.0011) and MSI (East: 0.5565 / 0.1856; West: 1.3993 / 0.0362). In conclusion, it is confirmed that during the 9 months that the monitoring lasted, there was no statistical correlation and that on average of the 9 images classified in Jenks Natural Breaks there is a correlation; TVX confirmed the influence of surface temperature on the state of vegetation within the forest over time.
