Resumo: | This research examines the spatial and temporal changes of the land use in the Bio-Bio Region (CentralSouth of Chile), for the years 1998 and 2008. We used the national monitoring digital coverage of 1998 and aerial photographs of 2008. Subsequently, we constructed matrices that explain the changes and transitions between different land uses. Plantations grew at an annual rate of 2.5 % due to grassland and shrub consumption in 21 %, agricultural land 14%, in mixed forest it grew by 8.8 % annually, while in wetlands it grew by 1.6 % and native forest had the least growth rate of 1.1 %. Grasslands and shrub lands showed a loss at a rate of 2.5 % per year caused mainly by their conversion into plantations at 21% and to other agricultural land uses at 2%. Agricultural land surface was lost at an annual rate of 1.5 %. Land plantations had a percentage increase of 14%. The wet lands lost surface equal to 0.4 %. The surface, which was, converted into urban and industrial areas represent 2.6 % and plantations 1.6 %. The main driver of land use change is the plantations because the Bio-Bio Region has the largest amount of surface area (858,592 ha) of the country with exotic plantations. |

Se utilizó la cobertura digital del monitoreo nacional del año 1998 y fotografías aéreas para el año 2008, posteriormente se construyeron matrices que explican el cambio y transiciones entre los diferentes usos del territorio. Las superficies con plantaciones crecieron a una tasa anual de 2,5 %, incremento generado por el consumo de praderas y matorrales en 21 %, terrenos agrícolas 14 %, bosque mixto 8,8 %, humedales en 1,6 % y bosque nativo en menor medida 1,1 %. Las praderas y matorrales presentaron una pérdida a una tasa de 2,5 % anual, la causa principal se debe a la transferencia de este uso a plantaciones con un 21 % y a otros usos como terrenos agrícolas 2 %. Los terrenos agrícolas perdieron superficie con una tasa anual de 1,5 %, terrenos que incrementaron a las plantaciones en 14 %, los humedales perdieron superficie con tasa de 0,4 %, la superficie se trasladó a las áreas urbanas e industriales en 2,6 % y plantaciones en 1,6 %. La principal presión para ocupar superficie, corresponde a las plantaciones, debido a que la Región del Bio-Bio representa la mayor cantidad de superficie (858.592 ha) de plantaciones exóticas del país.Universidade Federal de Santa Maria2018-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3534210.5902/1980509835342Ciência Florestal; Vol. 28 No. 4 (2018); 1831-1844Ciência Florestal; v. 28 n. 4 (2018); 1831-18441980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMspahttps://periodicos.ufsm.br/cienciaflorestal/article/view/35342/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessDíaz, Gastón VergaraVázquez, Víctor SandovalMachuca, Miguel Ángel Herrera2018-12-16T20:33:04Zoai:ojs.pkp.sfu.ca:article/35342Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-12-16T20:33:04Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
