Análisis multitemporal de la cobertura boscosa y páramos aplicando la metodología teledetección espacial y sig en la microcuenca del río Atapo Pomachaca provincia de Chimborazo.

Abstract

The present research project pursued to establish a multitemporal analysis of forest cover and moorland by applying spatial remote sensing and GIS methodology in the Atapo- Pomachaca River micro-watershed, province of Chimborazo. The project was carried out based on determining the characteristics of the Atapo-Pomachaca River micro-watershed located in Palmira parish, province of Chimborazo; its geographic coordinates are UTM zone 17 M, 755244 E in X and 9767635 S in Y, at an elevation of 2800-4280 meters above sea level. The type of research was framed on a purely field detail with respect to the application of GIS satellite information. The study was based fundamentally on description, observation and creation of a database design with the most outstanding characteristics of the forest cover and moorlands to be later analyzed and establish an objective criterion for the case. The results represented that between 2016 2017 period the increase or discussion of forested areas is a non-predictable issue. The socio- environmental diagnostic analysis was included in five strategic populated areas without vegetation cover, paramo and agricultural and livestock land. Similarly, the multitemporal analysis represents increase in certain forested areas in (2016-2017 and 2019- 2020 periods), the only year that presents a notable decrease was the (2018-2019 period) since all its approximations were negative. It is entirely concluded that each aspect focused on to an increase or decrease relates a large number of parameters that make its study a non-predictable situation. It is recommended to establish several and varied analyses to establish each of the aspects that directly influence the increase or decrease the forest area.
