ANÁLISE DA VARIAÇÃO DE TEMPERATURA DEVIDO À SUPRESSÃO VEGETAL - ESTUDO DE CASO.

Abstract

This paper presents a detailed analysis of the temperature variation caused by vegetation suppression and construction of the 9th Communications and Electronic Warfare Battalion in the Vila Sobrinho neighborhood, Campo Grande, MS. The research uses data from meteorological stations and satellite images, specifically from the Landsat 8 TIRS sensor, with the aim of evaluating the impact of urbanization on the local microclimate. Geoprocessing techniques were applied to classify areas of vegetation and built surfaces, identifying thermal variations over time. The results indicated that, after vegetation suppression, there was an increase in local temperatures, especially in areas with exposed soil and civil structures. This warming is associated with the replacement of native vegetation by materials that retain heat, evidencing the effect of urban heat islands. The comparison between satellite data and meteorological stations validated the accuracy of the data obtained externally, reinforcing the efficiency of the use of geotechnologies in this type of study. The statistical analysis carried out, corroborated by the Mann-Kendall test, confirmed the trend of increasing temperature in the study area. Thermographic images revealed that dense vegetation contributes to milder temperatures, while urbanization leads to thermal peaks. The study highlights the need to mitigate the impacts of urbanization by promoting environmental preservation and the creation of urban green areas. It is concluded that the removal of vegetation even in small areas significantly affects the microclimate, contributing to the increase in temperature. The research reinforces the importance of integrating green areas into urbanization projects, evolving towards improving the population's quality of life and environmental sustainability.
