Evaluación de diversidad, captura de carbono y material particulado de las especies forestales ornamentales en la zona urbana de Gualaceo

Abstract

Urban vegetation is of utmost importance as it provides ecosystem services such as carbon storage and removal of particulate matter from various anthropogenic processes in cities. In Gualaceo City, no studies have been conducted on of these pollutants captured by ornamental forest species. Our objective was therefore to determine the biodiversity, the amount of airborne carbon and the fine dust particles captured. His three parks in urban areas were investigated Parque del Niño, Simon Bolivar, 10 de Agosto, the biological corridor of the Santa Barbara River. Plots were plotted according to sample area at each site, abundance was identified using different diversity indices, and allometric equations were used for stored carbon and particle mass from leaf washing. Statistical analyzes and correlations were then performed to determine whether there was an association between variables. A total of 209 individuals were obtained, corresponding to 20 species. Salix humboldtiana (11896,7 gC/plant) and Jacaranda mimosifolia (7972,63 gC/plant) were significant in carbon sequestration. Hibiscus rosa sinensis (18,23 g/KgMS) and Eriobotrya japonica (25,39 g/KgMS) were significant in particulate matter. The correlations are positive linear relationships between carbon variables and DAP (k=0,82; p=0,0007) and altitude (k=0,67; p=0,0054) and negative linear relationships between particulate matter and altitude (k=−0,445; p=0,0663).
