RESUMO:

The development of human activities has constantly advanced on natural components, affecting their state of ecological balance due to the disturbances generated, constituting a challenge for management and planning. The objective of this work is to evaluate the environmental vulnerability of the landscape of the Mato Grosso municipality of Colíder, with the perspective that the data and information generated contribute to municipal environmental planning. The methodology used was based on the empirical analysis of the fragility of natural and man-made environments, which required the use of cartographic bases of geomorphology, geology, pedology and climate (precipitation); maps of vegetation cover and land use were prepared from images from Landsat 5 and 8 satellites, from 1984 to 2020; the Anthropogenic Transformation Index was applied to analyze anthropogenic pressure on landscape components over a 30-year period (1990 – 2020). The integrated data analysis made it possible to propose guidelines aimed at municipal environmental planning. Extensive livestock farming was identified as significant uses, followed by agriculture, which led to the suppression of native vegetation cover over the years. There were also changes in all other classes of native vegetation, which represents a reduction of 14.06% in vegetation cover, with the Submontane Open Ombrophilous Forest being the main class affected due to occupation in areas with characteristics conducive to the development of agricultural and livestock activities. agriculture. The land use with the greatest expansion was livestock farming (53.58%). The highest percentage of potential fragility/Stable in the municipality appears in the Weak category (76.37), followed by Average (15.86), Very Weak (3.02% and Strong (4.76%). In the municipality of Colíder 93.90% of its territory presented an unstable landscape. The state of conservation occurs in 64.79%, presenting itself as regular, it is worth highlighting that the greater the expansion of land uses, they can influence the state of conservation of nature and affect It was concluded that the areas covered by natural vegetation in the Municipality decreased due to livestock and agriculture, influencing the fragility and ecodynamic stability of the Municipality's landscape components.
