Estimación de la capacidad potencial de fijación de CO2 y producción de O2, Como servicio ecosistémico brindado por el arbolado del parque los fundadores y la alameda de la avenida 40 en el Municipio de Villavicencio (Meta)

Abstract

The project was developed in the Fundadores Park, located in the south of the Villavicencio City and in the Alameda the 40th avenue, up to the point of Unicentro, the mall and with the objective of estimating the potential capacity of the trees to fix CO2 and produce O2 at present and in a time of 10 years, considering the requirements of direct users. This is the biggest urban park in the municipality of Villavicencio with an approximate area of 10 ha.A forest inventory of individuals with a diameter at breast height (DBH) equal to or greater than 15 cm, identifying the species, DBH, total height, crown health, sun exposure, use of the soil and the basic density of the wood that was found through the dry weight method per unit of green volume, this information was processed by a allometric equations with theoretical density, experimental and software i-Tree ECO, later an analysis of variance was made and the test of Tukey by species to determine the similarity between the treatments and to reach a consensus of CO2 fixation and O2 production. Based on the data obtained, a balance was made considering the respiration rate of the persons determining if the study area has the capacity to supply these needs. Finally, the projection of these ecosystem services was carried out through the annual average increase (MAI) for a period of 10 years. The results of the investigation showed that the study area has a carbon storage of 349.2 tons and a CO2 fixation of 1281.7 tons, with Ficus benjamina standing out with 936.4 tons corresponding to 73.03% of the total fixation, followed by the species Tabebuia rosea with 63.5 tons, Likewise, forest species have produced a total of 920.78 tons of O2 with an annual production of 51.73 tons, It was also possible to determine that the tree supply satisfies the requirements of the direct users in terms of the respiration rate with efficiencies of more than 6000% in a period of 1 year. Finally, through the projection made, it is estimated that the study area will fix 660.3 tons of CO2 and produce 479.7 tons of O2 in 10 years. Concluding that the study area has a good potential capacity at present and in a time of 10 years to provide these ecosystem services.
