Análise espacial dos focos de queimadas no estado do Pará, no período de 2015

The fires are presented with a major problem of irrational use of natural resources, thus contributing to global warming and cause various economic, social and environmental problems. Therefore, the aim of this study was to analyze the spatial distribution of outbreaks of fires in Para State, relating to environmental variables and the air pollutants resulting from burning in the year 2015. For this research were used data from INPE, IBGE, PRODES, SISAM, INMET and other secondary sources. The processing, analysis and interpretation of data were performed using the spatial distribution and use of IDW tools and Zonal Statistics as Table in ArcGIS software provided by the IEC (Evandro Chagas Institute) and CRA-INPE (Amazon Regional Center). From the analysis of fire outbreaks, there was strong relationship between the outbreaks and environmental variables such as rainfall and temperature, because there is a decrease of outbreaks over higher rainfall, and a sharp increase in less rainy season. Environmental pollutants also had relation with the focus of fire, carbon monoxide rates show a decrease in periods with higher precipitation, and increased less rainy periods, as well as particulate matter that had some relationship with the outbreaks. In this way, there is the importance and efficacy of the use of geotechnologies like the spatial distribution and the use of other methodologies in environmental problems.
