Evaluación de zonas arbóreas y su incidencia en la temperatura superficial terrestre en el casco urbano de la ciudad de Olmedo

The urban heat island phenomenon has been exacerbated by the expansion of urban areas and the reduction of vegetation cover, constituting a global environmental challenge. In this context, the present study focused on analyzing the role of urban vegetation as a mitigating factor of heat islands in the urban core of the city of Olmedo. The research was conducted in three main stages: initially, the vegetation of the urban core was characterized and Landsat 8 satellite images were obtained to calculate the Normalized Difference Vegetation Index (NDVI). Subsequently, land surface temperature and urban heat island intensity were determined using QGIS 3.28.5, generating thematic maps that reflected the spatial distribution of urban heat. Finally, the relationship between NDVI and land surface temperature was evaluated using statistical analyses in IBM SPSS Statistics. The results showed that vegetation density in the urban core is low, with low NDVI values, while the Centro and San Andrés neighborhoods exhibit the highest levels of heat island intensity. This study demonstrates that areas with lower vegetation cover coincide with higher temperatures, emphasizing the need to develop urban management models that strengthen vegetation as a thermal mitigation strategy.
