A degrada\u00e7\u00e3o em \u00e1reas naturais protegidas por Lei tem aumentado nos \u00faltimos anos. Logo, \u00e9 necess\u00e1rio desenvolver estrat\u00e9gias para monitorar o espa\u00e7o e gerar subs\u00eddios \u00e0 fiscaliza\u00e7\u00e3o em tempo h\u00e1bil. Mapeamentos sistem\u00e1ticos anuais podem cumprir essa miss\u00e3o, por\u00e9m, em regi\u00f5es cujo uso da terra \u00e9 heterog\u00eaneo, fitofisionomias de vegeta\u00e7\u00e3o natural n\u00e3o-florestal s\u00e3o, comumente, confundidas com \u00e1reas antropizadas para pasto, especialmente no bioma Cerrado. Assim, o objetivo do presente estudo foi apresentar a t\u00e9cnica GEOBIA para avalia\u00e7\u00e3o da din\u00e2mica temporal do uso e cobertura da terra no Parque Nacional da Serra da Canastra (PNSC), localizado no Estado de Minas Gerais, entre os anos de 2005 e 2015. Para tanto, foram ponderadas a informa\u00e7\u00e3o espectral de cada pixel, as informa\u00e7\u00f5es referentes aos indicadores fenol\u00f3gicos, e as informa\u00e7\u00f5es de forma, textura e contexto de objetos segmentados. Os resultados apontaram o aumento de 2.606,82 ha (1,32%) da \u00e1rea antropizada no PNSC, o que torna necess\u00e1rio aumentar medidas mitigat\u00f3rias na regi\u00e3o e intensificar fiscaliza\u00e7\u00f5es. Diferente de mapeamentos sistem\u00e1ticos, o m\u00e9todo proposto \u00e9 capaz de subsidiar a tomada de decis\u00f5es em Unidades de Conserva\u00e7\u00e3o heterog\u00eaneas.<\/p>\n\n\n\n

GEOBIA technique and changes in the landscape of protected natural areas: a case study in the Serra da Canastra National Park (Brazil)<\/p>\n\n\n\n

Degradation in natural areas protected by Law has increased in recent years. Therefore, it is necessary to develop strategies to monitor the space and generate subsidies for prompt inspection. Annual systematic mapping can fulfill this mission, however, in regions whose land use is heterogeneous, phytophysiognomies of natural non-forest vegetation are commonly confused with anthropized areas for pasture, especially in the Cerrado biome. Thus, the objective of the present study was to present the GEOBIA technique for assessing the temporal dynamics of land use and cover in the Serra da Canastra National Park (PNSC), located in the state of Minas Gerais, between 2005 and 2015. For so much, the spectral information of each pixel, the information referring to the phenological indicators, and the form, texture, and context information of segmented objects were weighted. The results showed an increase of 2,606.82 ha (1.32%) of the anthropized area in the PNSC, which makes it necessary to increase mitigation measures in the region and intensify inspections. Unlike systematic mappings, the proposed method can support decision-making in heterogeneous Conservation Units.<\/p>\n\n\n\n
