Analizar el cambio de uso de suelo en el páramo Guagua Pichincha, cantón Quito, provincia de Pichincha.

Abstract

This research aimed to analyze the change in land use and vegetation cover study. It was carried out in Lloa town in the Guagua Pichincha moorland between the years 2015-2019. For this study, the geographical points of the study area were taken using a GPS and then uploaded to the ArcMap program, delimiting the area for subsequent multi-temporal analysis. So, Landsat 8 satellite images were downloaded from 2015 to 2019. For the comparison of results, information was taken from the country's planning secretariat, and the supervised classification was established in the program. Finally, quantification maps were created in hectares that classified the land use of the study area. The subsequent years were compared to determine the annual rate of change in land use, vegetation cover, and the calculation of the normalized differential vegetation index (NDVI). The changes that occurred in the study area from 2015 to 2019 were: an increase in land use for agricultural land from 1069.62 ha to 1120.54 ha, a decrease in paramo areas from 263.22 ha to 227.33 ha, a decrease in shrubby vegetation from 280.32 ha to 263.97 ha, an increase in a populated area from 11.66 ha to 12.99 ha. There was evidence of a severe change in land use and vegetation cover in Lloa in the years studied. So, the implementation of projects that correct this problem is recommended.
