Evaluación comparativa del stock de carbono del suelo en tres ecosistemas forestales de la Provincia de Chimborazo

Abstract

This research aimed to value the storage capacity of soil organic carbon in forest ecosystems since it is essential due to its high vulnerability to climate change in recent years. This research is descriptive since methods were used to detail each of the physical-chemical properties, such as the characteristics of the carbon stock stored in the different types of soils and the necromass of forest ecosystems. Specific data is needed to estimate the organic carbon concentration in each forest ecosystem. The study area's delimitation was carried out with the help of the geographic information tool ArcGIS to get to know the areas of the forest ecosystems sampled within the province of Chimborazo. For Eucalyptus Globulus, an area of 10.6 ha was estimated; for Pinus Radiata, 142 ha was estimated; and for the Primary Forest, an area of 57.2 ha was estimated. The carbon stock content of the three forest ecosystems was evaluated, giving us the highest concentration in the primary forest with a percentage of 9.7323%, 1852.29 ± 0.09 in tC/ha. Then there is the Pinus Radiata plantation. With a percentage of 1.0667% being in tC/ha 255.01 ± 0.09. Lastly, the plantation of Eucalyptus Globulus is placed with a percentage of 0.7404%, being 163.02 ±0.03 in tC/ha.
