Identifica??o de áreas para recomposi??o florestal com base em princípios de ecologia de paisagem

摘要

Forestland management based on landscape ecology principles is a tendency in the forest sector, whose proposal is the integrated management of economic, social, and environmental factors, taking into account complex decisions supported by geospatial technologies. The objective of this study was to develop a methodology to apply the concepts of landscape ecology in land use planning of forest farms, using Geographic Information System techniques. The study area was a forest farm owned by the International Paper do Brasil. Five criteria were used to identify suitable areas for forest recovery: soil fertility, existing native forest patches, water bodies, slope, and erosion susceptibility. These factors were analyzed through the multi-criteria decision resources in a GIS environment. The result was a map showing suitable areas for forest recovery, according to the defined criteria. Based on this map, a simulation was made to allocate a new forest area and the results were evaluated at a landscape level using proper indices.
