Análise da paisagem no entorno do município de Indianópolis, MG, Brasil.

Abstract

Landscape analysis by means of metrics is one of the means of assessment that studies regional dynamics, as it is influential over a long territorial space and thus makes it possible to better understand the ecology of species. In this way, the present work had as general objective to carry out a wide analysis of the landscape to evaluate the changes in the use of the land, in three series of 10 years, starting in (1988 to 2018) in the radius of 100 km around a great pole eucalyptus forestry plant located in Indianópolis. The cities of Araguari, Cascalho Rico, Estrela do Sul, Grupiara, Indianópolis, Iraí de Minas, Monte Carmelo, Nova Ponte, Pedrinópolis, Pilgrimage, Santa Juliana, Uberaba and Uberlândia were selected within a radius of 100km - 11 cities. For landscape analysis, data from the Annual Coverage and Land Use Mapping Project in Brazil (MapBiomas) were used. ArcGis 10.8 software was used for editing and manipulating image processing. With the aid of the patch analyst plugin, the area, size, shape and central area metrics will be processed. Landscape changes during the period will be assessed using the t test. The results indicate that the changes during the 30 years were diverse in the landscape, such as the territorial replacement of pasture areas by perennial, annual and semi-perennial crops, the increase of planted forests to 84.51 km² (2018) in Indianópolis, Grupiara and Uberaba, the behavior of savanna and rural forest patches are with the dimensionless AWMSI indexes in the values of 1.78 and 3.20 and MSI 1.33 and 1.43, with undesirable edge perimeters at the end of the series. The study area showed an increase in forest material in the years 2008 to 2018 with a result of 0.0157 p-value in the metric of class area due to an increase of 10.14 km² on average. The use of geoprocessing tools and geographic information systems are important to understand the landscape and allow to direct appropriate strategies to the managers of public and private agencies regarding the improvement of environmental management.
