Resumo: | DOI: http://dx.doi.org/10.12957/geouerj.2014.11739The objective of this study was to analyze the structural changes of the landscape in the River Basin of the Aguapeí River/MT, in the years 1991 and 2011, through the use of geotechnologies and metrics. This study is based on a categorical approach, which classes discrete belonging to the vegetation cover and land use were identified and mapped by means of geotechnologies and characterized quantitatively by indices of Landscape Ecology, adopting the conceptual model of "stain-corridor-matrix'. It was found that the landscape of the study area form a mosaic, showing an array consisting of savanna (Cerrado), with several spots of livestock, and an area of influence urban, being that the latter class did not exist in 1991, and the corridor formed by alluvial forest in River Basin of the Aguapeí. The data showed a decrease in the area occupied by savanna vegetation and the growth of the agricultural activity in the period analyzed. In case of this pattern is maintained, indicates that in the next 20 years may be the matrix of the basin be constituted by agricultural activity resulting in simplification of ecosystems. Thus, there is a need for regional development policies of Mato Grosso prioritize environmental conservation, which will reflect in land use planning, to improve the permeability of the landscape. |

Este estudo é baseado numa abordagem categórica, cujas classes discretas pertencentes à cobertura vegetal e uso da terra foram identificadas e mapeadas por meio das Geotecnologias e caracterizadas quantitativamente por índices de Ecologia de Paisagem, adotando o modelo conceitual de “mancha-corredor-matriz”. Verificou-se que a paisagem da área de estudo forma um mosaico, apresentando uma matriz constituída por Savana (Cerrado), com diversas manchas de Agropecuária e uma de área de Influência urbana, sendo que esta última classe não existia em 1991, e o corredor formado pela Floresta aluvial do Rio Aguapeí. Os dados evidenciaram um decréscimo da área ocupada pela vegetação de Savana e o crescimento da atividade agropecuária no período analisado. Caso este padrão seja mantido, indica que nos próximos 20 anos poderá a matriz da bacia ser constituída pela atividade agropecuária implicando em simplificação dos ecossistemas. Sendo assim, há necessidade de que as políticas de desenvolvimento regional de Mato Grosso priorizem a conservação ambiental, o que irá refletir no planejamento do uso da terra, para melhorar a permeabilidade da paisagem.Universidade do Estado do Rio de Janeiro2014-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.e-publicacoes.uerj.br/geouerj/article/view/1173910.12957/geouerj.2014.11739Geo UERJ; v. 2 n. 25 (2014): Jul/Dez; 397-4181981-90211415-7543reponame:Geo UERJinstname:Universidade do Estado do Rio de Janeiro (UERJ)instacron:UERJporhttps://www.e-publicacoes.uerj.br/geouerj/article/view/11739/10991Neves, Laís Fernandes de SouzaNeves, Sandra Mara Alves da SilvaNeves, Ronaldo Joséinfo:eu-repo/semantics/openAccess2022-02-20T21:10:54Zoai:ojs.www.e-publicacoes.uerj.br:article/11739Revistahttps://www.e-publicacoes.uerj.br/index.php/geouerjPUBhttps://www.e-publicacoes.uerj.br/index.php/geouerj/oaitunesregina@gmail.com || ppeuerj@eduerj.uerj.br || geouerj.revista@gmail.com || glauciomarafon@hotmail.com1981-90211415-7543opendoar:2022-02-20T21:10:54Geo UERJ - Universidade do Estado do Rio de Janeiro (UERJ)false |
