- Abstract
The object of this paper was to evaluate the use of the Kernel density method in the spatial and temporal analysis of heat foci in integral protection conservation units of the Espinhaço Range Biosphere Reserve. For that, vector images of the years 2000, 2005, 2010, 2015 and 2017 were analyzed and processing was performed by QGIS software 2.18.16, from the overlapping of these with the records of heat sources. The heat foci density was calculated using the Kernel estimator and five levels of classification were used: very low, low, medium, high and very high. It was demonstrated the heat sources representation for the cited years and their relation to the concentration of fire risks in areas of the RBSE, leading to the perception of the simulations over the years, corroborating with forest fire records. The Kernel Density estimation showed the ability to indicate the distribution and intensity of the foci, constituting an interesting tool to guide prevention and surveillance activities.
