Contribución de las especies forestales ornamentales en el secuestro de carbono y material particulado en cuatro parques urbanos de la ciudad de Cuenca

Abstract

Ornamental forest species are present in the city of Cuenca either in green or urban areas, however, there is misinformation about the benefit of these, which is why in the present study, it was proposed to determine the richness of ornamental forest species in the four urban parks in the city of Cuenca, estimate the amount of carbon fixed in ornamental forest species and quantify the amount of particulate matter adhered to the leaves of the species. Four parks in the city were selected: Parque de la Madre, Miraflores, Paraíso and Tarqui Guzho, where areas of greatest dominance of species were determined, delimiting an area of 1 600 m2 divided into 4 "blocks" of 400 m2 each. To estimate the amount of richness, an inventory of the species present was carried out, obtaining a total of 157 species among all the parks. For the analysis of the data, a Shapiro Wilks test was carried out to identify if there is normality in its data, later we carried out a Kruskal Wallis test to identify the significance in relation to the data obtained for the amount of carbon per park and per species. where the El Paraíso park assimilates greater amounts of carbon in the species present with a value of 27 575,58 Mg C/ha and species such as Acacia dealbata and Salix humboldtiana. Regarding the analysis of particulate material, Yucca guatemalensis and Delostoma integrifolium were obtained as species that assimilate the greatest amount of MP with 0,254 and 0,196 respectively, however, there was no significant difference between the adherence of particulate material to the leaves of the species. present in the parks. With the information obtained in this study, we can recommend the municipal companies in charge of planting green areas in the city of Cuenca, to consider the species that help improve environmental pollution conditions through carbon assimilation and adherence of material. particulate to its leaves.
