ANALYSIS OF LANDSCAPE FRAGMENTATION OF THE MUNICIPALITY OF NOVA MARILÂNDIA-MT, BRAZIL

Abstract

This work aims to analyze the state of fragmentation of the landscape of the municipality of Nova Marilândia - Mato Grosso, aiming at generating information that supports the proposition of planning strategies for the conservation and restoration of landscape functionality. Maps of vegetation cover and land uses were generated from images of Landsat 5 satellites, from 1998 and 2008, and Landsat 8, 2018. Georeferencing, clipping and classification processes were performed. The application of statistical calculations relating to the structure of the landscape was operationalized in the Fragstats programme. In the analysis period, there was high anthroporization in the landscape of the municipality, implying the reduction of the areas of the classes of Natural Forest Vegetation (10.49%) and Savannah Formation (20.95%), and a growth in Pasture areas (36.00%) Agriculture (103.74%), resulting in increased fragmentation of the municipal landscape. It was concluded that there was an increase in the complexity of the forms and distances between the fragments of native vegetation and the reduction of functional connectivity, caused by the expressive growth of the areas of Agriculture and Pasture, which constitute the the main economic bases of the municipality.
