Análisis multitemporal del cambio de cobertura y uso del suelo en el área de estudio localizada en la microcuenca del río Capulí, provincia de Cañar.

Abstract

The objective of the research was to analyze the change in land cover and land use in the study area located in the Capuli river micro-watershed, province of Cañar, in the years 2000, 2005, 2010, 2015 and 2020, to achieve this goal, the land cover and land use by means of the classification based on Landsat satellite images and the rate of change of land cover and land use was determined based on classified images. The supervised classification method was applied using Landsat images Landsat 7 of Huayrapalte hill, located within the Capulí river micro-watershed Suscal canton, province of Cañar. Each image was assigned to a correction and classification process supervised in the ENVI 5.3 software to subsequently make maps with the help of ArcGis 10.5 software. The classification was validated with confusion matrices where the kappa indices presented values between 0.654 and 0.937. The annual rates of change resulted in an increase of 2.21% of the páramo, 1.52% of the native forest, 0% of the populated zone, and while in the agricultural and livestock of -0.92%, accepting the alternative hypothesis. It was concluded that there is a loss principally of native forest, páramo, and at the same time the populated zones, while in the agricultural zone showed an increase due to the agricultural frontier, deforestation and the lack of protection of the existing native forest in the study area. It is recommended to implement alternative technologies for a constant monitoring of the changes, expand the research on the effects on the intensity, duration and frequency of rainfall in the micro-watershed of the Capuli river and conduct a study on the current management of the waste generated by the tourist activity.
