SPACE-TEMPORAL DYNAMICS OF THE LAND USE OF PARK OF CORUMBIARA/RONDÔNIA STATE

DINÁMICA ESPACIO-TEMPORAL DE LA CUBIERTA DE LA TIERRA EN EL PARQUE ESTADUAL DE CORUMBIARA/ESTADO DE RONDONIA

No Brasil, em especial no estado de Rondônia, a territorialização, impulsionada pelos programas do Governo Federal nos anos 70, resultou na degradação dos recursos naturais. Com isso, o governo do estado criou áreas de proteção ambiental. A partir de tal constatação o trabalho teve como objetivo caracterizar a dinâmica espacial e temporal da cobertura da terra do Parque Estadual de Corumbiara, em quatro períodos distintos. Para isso, utilizaram-se imagens de sensoriamento remoto orbital dos anos de 1990, 2000, 2014 e 2017, que foram manipuladas em Sistemas de Informações Geográficas (SIGs), onde empregaram-se técnicas de processamento digital de imagens. Os resultados revelaram as alterações da vegetação ao longo do período analisado e indicou consolidação da área antropizada, que passou de 5.814 hectares, no ano de 1990 para 22.796, no ano de 2017, a uma taxa de crescimento de 74,49% e o fator determinante para tal crescimento foi a redução da área do parque no ano de 2002.

ABSTRACT
In Brazil, especially in the State of Rondônia, the occupation of territory, driven by programs of the federal government in the 70's, has resulted in the degradation of natural resources. With this, the State Government created environmental protection areas. From such finding, the work aimed to characterize the occupation of physical environment of the Corumbiara State Park, as well as their buffer zone in three distinct periods. For this, it was used remote sensing images of years 1990, 2000, 2014 and 2017, which were handled in Geographic Information Systems (GIS), where techniques of digital image processing were employed. The results revealed vegetation changes during the analyzed period and indicated consolidation of the anthropic area, from 5,814 hectares in 1990 to 22,796 in 2017, at a growth rate of 74.49% and the factor was the reduction of the park area in 2002. The results revealed vegetation changes during the analyzed period and indicated consolidation of the anthropic area, from 5.814 hectares, in the year 1990 to 22.796, in the year 2017, at a growth rate of 74.49% and the determining factor for such growth was the reduction of the park area in the year 2002.

Keywords: Special Areas; Western Amazon; Vegetation Mapping.

RESUMEN
En Brasil, en especial en el estado de Rondônia, la territorialización, impulsada por los programas del gobierno federal en los años 70, resultó en la degradación de los recursos naturales. Con ello, el gobierno del estado creó áreas de protección ambiental. A partir de tal constatación el trabajo tuvo como objetivo caracterizar la dinámica espacial y temporal de la cobertura de la tierra del Parque Estadual de Corumbiara, en cuatro períodos distintos. Para ello, se utilizaron imágenes de teledetección de los años 1990, 2000, 2014 y 2017, que fueron manipuladas en Sistemas de Información Geográfica (SIGs), donde se emplearon técnicas de procesamiento digital de imágenes. Los resultados revelaron las alteraciones de la vegetación a lo largo del período analizado e indicó la consolidación del área antropizada, que pasó de 5.814 hectáreas, en el año de 1990 a 22.796, en el año 2017, a una tasa de crecimiento del 74,49% y el factor determinante para tal crecimiento fue la reducción del área del parque en el año 2002.
