Análisis multitemporal del cambio de uso de suelo en la parroquia Quimiag en los periodos 2010 – 2015 y 2015 – 2020

The change in land use is a global problem that needs to be quantified to establish viable alternatives for its control; In this sense, the objective of this study was to carry out a multitemporal evaluation of soil change in the Quimiagparish, Riobamba canton, in the period 2010 -2015 and 2015 -2020—an experimental and diagnostic methodology applied with a quantitative design. For data collection, stratified random sampling was applied, while to quantify the change in existing land uses, we worked with Landsat-type satellite images acquired from the "Earth Explorer USGS" platform and applied a rectification process using the QGIS software, obtaining the soil change rate, which indicated that in the period 2010-2015, the forest presented the most significant reduction with 5.37%, while agricultural land revealed a gain of 16.85%; Concerning the period 2015-2020, it was obtained that other lands presented the most remarkable negative change corresponding to 27.78%, while agricultural landpresented an increase of 21.13%. Subsequently, the physicochemical properties of each of the analyzed land uses were determined, noting that in all cases, there are differences in the values obtained; Finally, a comparison of the physicochemical properties of the soil was made from the statistical analysis of Anova and Tukey, getting that the apparent and natural density, pH, conductivity, organic matter, and porosity present statistically significant differences.
