| description | This paper evaluated the tropical humid forest at Yuracyacu watershed during the period 1989-2010. For this, 6 Landsat satellite images were used from the Thematic Mapper sensor for the years 1989, 1995, 2001, 2006, 2008, 2010, which the respective processing was carried out using CLASlite by analyzing the fractional cover. During the period 1989-1995 a loss of 18.2 km2 of the forest cover was obtained, for the period 1995-2001 the forest cover was recovered in a ratio of 1.2 km2/year; for the periods 2001-2006, 2006-2008, and 2008-2010 it was pbserved the progressive decline of the tropical rain forest, these losses being 8.9 km2, 3.4 km2 and 7.5 km2 respectively. In the 21 years, 32 km2 of Amazon rainforest have been lost from the sub-basin with a deforestation rate -1.2% per year, the highest rate of deforestation was found in the period 1989-1995, which is -2.27%. The model for determining future tropical forest scenarios in the watershed estimated a resulting area of 89.1 km2 by 2030, demonstrating the progressive decrease of tropical humid forest. Finally, in the validation of the results, a global reliability of 85% and a Kappa index of 0.65 were obtained indicating the goodness and precision of the classification. The results of this study will guide actions for the conservation and management of the tropical rainforest of the watershed. |

En este estudio se evaluó la cobertura boscosa en la subcuenca del río Yuracyacu durante el periodo 1989-2010. Para esto se utilizaron 6 imágenes satelitales Landsat del sensor Thematic Mapper de los años 1989, 1995, 2001, 2006, 2008, 2010, sobre las cuales se realizaron los respectivos procesamientos utilizando CLASlite mediante el análisis de la cobertura fraccional. Durante el periodo 1989-1995 se obtuvo una pérdida de 18.2 km2 de la cobertura boscosa, para el periodo 1995-2001 la cobertura boscosa fue recuperada con una tasa de 1.2 km2/año; para los periodos 2001-2006, 2006-2008 y 2008-2010 se evidenciaron los progresivos retrocesos del bosque húmedo tropical, siendo estos 8.9 km2, 3.4 km2 y 7.5 km2, respectivamente. En los 21 años se han perdido 32 km2 de bosque tropical amazónico de la subcuenca con una tasa de deforestación -1.2% anual; la tasa de deforestación más alta se encontró en el periodo 1989-1995 y fue -2.27%. El modelo para determinar escenarios futuros de bosque tropical en la subcuenca estimó un área resultante de 89.1 km2 para el año 2030, demostrando la progresiva disminución de bosque húmedo tropical. Finalmente, en la validación de los resultados se obtuvo una fiabilidad global igual a 85% y un índice de Kappa de 0.65 indicando la bondad y precisión de la clasificación. Los resultados de este estudio permitirán orientar acciones para la conservación y manejo del bosque húmedo tropical de la subcuenca.
