Análisis multitemporal de la cobertura boscosa empleando imágenes satelitales en la parroquia La Paz, Yacuambi, provincia de Zamora Chinchipe, en el período 2015-2020.

Abstract

The main aim was to analyze forest cover using satellite images for 2015-2020 period. A descriptive and non-experimental explanatory analysis methods were applied, which allowed the information gathering, on the loss of forest cover caused by excessive logging, performing the classification of coverage using ArcMap software, which permitted the analysis and evaluation of the variation of changes in forest cover. Five categories with gains and losses were determined during the study period, as detailed below: there was a loss of 1543.44 ha, which represents 3.04% in the Forest category, for the Agricultural Land category there is an increase of 1376.35 ha, which represents 11.71% gain, for the Shrub and Herbaceous Vegetation category there is also an increase of 167.10 ha, which represents 15.08% gain and for the Populated Area category it is maintained with 52.42 ha, and the Water Bodies category which is maintained with 149.67 ha. With the changes obtained for the Forest category, it could be deduced that there was a great loss of forest cover. Therefore, the alternative hypothesis is accepted, there is a reduction in forest cover through the multitemporal analysis in the parish of La Paz during the 2015-2020 period. Therefore, it is recommended to carry out constant multitemporal analysis of the cover, which allows us to know the state of the forest and to have a better perspective of the changes occurred over the years.
