Análise da dinâmica do fluxo de CO2 sob diferentes coberturas vegetais no bioma Mata Atlântica

Abstract

Soil is an important carbon store, playing a fundamental role in controlling emissions of this and other gases into the atmosphere. Soil use and management practices can act both positively and negatively in this storage process. This study aims to analyze the dynamics of the flow of CO2, which is one of the most important greenhouse gases, in the same type of soil and in areas with and without the presence of vegetation cover in the Atlantic Forest Biome, which is one of the most degraded biomes in Brazil, in areas located on campus I of the Federal University of Paraíba. For this study, a mobile CO2 flow meter, the LI8100A – IRGA, was used, with data collection at times of higher and lower air temperature over the course of a week. The results showed that the flow is always positive in the area with vegetation, contrary to that found in the area without vegetation cover.
