Abstract

Landscape pattern indicators or landscape metrics are based on landscape ecology, an interdisciplinary area of study dedicated to understanding how disturbances influence the organization, functioning, composition and transformations of landscapes. Metrics provide simple measures of the structure in which a given landscape is found and can be obtained by applying geoprocessing techniques. The objective of this work was to understand the structural dynamics of the landscape in three conservation units (CUs), one of full protection and two of sustainable use in the state of Tocantins, through the application of digital image processing techniques and application of spatial metrics of the landscape. Remote sensing satellite images from the LANDSAT series for the years 2000, 2010 and 2020 were used. The images underwent object-oriented classification processes of land cover for each period with the application of machine learning techniques. Landscape metrics were applied to the land cover classification product to identify the degree of fragmentation of the CUs analyzed. In general, a reduction in native vegetation was observed over time in all conservation units analyzed in comparison with the other land cover classes, being replaced, mostly, by agricultural crops and livestock. A significant worsening in landscape metrics was also observed, highlighting the high degree of fragmentation of native vegetation in these CUs.
