Temporal Analysis and Environmental Modeling of Native Forest in Roca Sales Municipality - RS
Main Article Content
Abstract
The availability of satellite images from the same region of the Earth, spaced in the time, allows the detection of land use
and land cover changes and the future scenarios development by simulation models. This paper aims to perform
temporal analysis of the native forest of the Mata Atlântica Biome, located in Roca Sales/RS municipality, for the years
1989, 1999 and 2009. Other objective is organizing a spatial dynamic model to project a future scenario of the native forest
to the year 2020. The landscape temporal analyses were realized by recursive comparison of Landsat 5 satellite classified
images and the spatial temporal model was developed on Dinamica software. The results showed that the abandoned
agricultural areas in Roca Sales are being progressively converted into native forest, mainly in areas with high elevation
and high slopes. The native forests increased 76.45% on the landscape analyzed in 20 years. By the year 2020, the tendency points towards the maintenance of the natural forest cover regeneration process.
