Reflections of the Colonization Model on Vegetation in the Urban Area of the City of Jaru - Rondônia

Abstract

The present work evaluates the effects of the colonization model on the distribution of vegetation, from the beginning to the most recent period (1975 to 2016), in the urban area of the city of Jaru - kRO, by using geotechnologies. For that, images of the satellite Landsat 2, 3, 5 and 8 were used based on geoprocessing techniques to generate spatial information that allowed the delimitation of portions of the terrain with the mapping of land use and occupation. The period between 1975 and 1990 was characterized by intense anthropic activity in the natural landscape due urbanization and agriculture, reducing the distribution of natural vegetation cover by 80.38% and increasing the distribution of water bodies by 0.26%. On the other hand, the period from 2000 to 2016 showed an increase of plant cover by 7.72% due to the natural regeneration of abandoned areas. This was possibly due to of the attempt to modify the environmental trend in the state of Rondônia, aiming to soften the scenario of native forest destruction as a result of the most intense period of this colonization.
