Análisis espacio temporal del cambio de cobertura vegetal en el Área de Protección Hídrica Quinllunga, San Simón, provincia de Bolívar

Abstract

The present study investigates the spatiotemporal analysis of the dynamics of vegetation cover in the Quinllunga Water Protection Area, located in Bolívar province, in San Simón parish, in the last 40 years through geographic information systems. The satellite images were obtained from the Google Earth Engine platform with the help of a programming code, which sought to find several angles of cloud-free photographs and form one in which its vegetation can be visualized. With the help of the ArcMap software, the Unsupervised classification was obtained, being the beginning to carry out the Supervised classification of the study area. In the period between 1980 and 2023, around 7 classes of vegetation cover were identified, and these are: shrubs, wetland, grassland, cushion, moorland burning, rocky outcrop and forest plantation. During the study period there was an increase and decrease in the different classes, especially the grassland, which had a notable discussion of 131.9 ha. The burning of grassland was seen during 1990 to 2000 and at present. Among the proposals for the conservation of the study area is the restoration of affected areas and recovery of habitats, as well as the adoption of new agricultural practices according to their needs and being friendly to the environment.
