Resumo: Amazonia has undergone severe changes caused by human activities, among which stands out the transformation of forest areas in areas of agricultural use, resulting in the intensification of erosion processes. In this context, the aim of this study was to apply the empirical model RUSLE (Revised Universal Soil Loss Equation) in the upper reaches of the Prata catchment. The catchment with an approximate area of 32,7 km², which is located in the municipality of Capitão Poço (state of Pará), approximately 160 km from the capital Belém. The methodology consisted of the construction of a base georeferenced data, which have undergone adjustments for inclusion in the GIS. The data and application of GIS with RUSLE allowed the generation of a map of soil loss in the study area, which was used for the determination of soil loss tolerance of the catchment. The Prata catchment presented values of soil loss ranging between 0.004 and 72.48 t ha-1 year-1, and an average of 5.12 t ha-1 year-1. In this case, approximately 12 % of the catchment area presented environmental risks due to erosion.Keywords: Amazon; erosion; GIS; change of land use.

Nesse contexto, o objetivo deste trabalho foi aplicar o modelo empírico RUSLE (Revised Universal Soil Loss Equation) no trecho superior da bacia do igarapé da Prata. A bacia, com uma área aproximada de 32,7 km², fica localizada no município de Capitão Poço/PA, aproximadamente 160 km da capital Belém. A metodologia empregada constou da construção de uma base de dados georreferenciada, que passou por adequações para inserção no ambiente SIG. Os dados e o SIG com aplicação da RUSLE permitiram a geração de um mapa de perda de solo da área de estudo, o qual foi utilizado para a determinação da tolerância de perda de solo da bacia. Assim, a pequena bacia do igarapé da Prata apresentou valores de perda de solo, variando entre 0,004 e 72,48 t ha-1 ano-1, com uma média de 5,12 t ha-1 ano-1. Nesse caso, aproximadamente 12 % da área da bacia apresentam riscos ambientais devido aos processos erosivos.Palavras-chave: Amazônia, erosão, SIG, mudança de uso do solo.Universidade Federal do AmapáCAPESSantos, Diego Benvindo OliveiraBlanco, Claudio José CavalcantePessoa, Francisco Carlos Lira2015-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/156910.18561/2179-5746/biotaamazonia.v5n4p78-83Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 5, n. 4 (2015); 78-832179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/1569/v5n4p78-83.pdfAmazônia, pará, Brasil, américa do SulDireitos autorais 2015 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-03-29T17:50:53Zoai:ojs.pkp.sfu.ca:article/1569Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-03-29T17:50:53Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
