Resumo: The studies that have as theme the environmental degradation and its consequences are at the center of discussions. This research aims to assess the ratio of normalized difference vegetation as a way to help the analysis of the degradation of the Serra da Meruoca-CE. The study area is located in the western part of the state of Ceará, comprising part of six cities, including two municipalities with full participation.The materials used were satellite images, which were processed in ArcGIS software and Spring and rainfall data provided by FUNCEME.We emphasize the importance of analyzing the vegetation cover in the study of degradation.With maps generated together with graphs of rainfall and water balance, it is clear that suppression of vegetation cover in the Serra da Meruoca-CE, this is because even in 2013, with a more positive fluid balance of the year 1993 the response of vegetation cover was lower than the year 1993.

A presente pesquisa, tem como objetivo principal analisar o índice de vegetação por diferença normalizada, como forma de subsidiar a análise da degradação da Serra da Meruoca-CE. A área de estudo localiza-se na parte oeste do Estado do Ceará, perfazendo parte de 6 municípios, sendo dois municípios com participação total. Os materiais utilizados foram imagens de satélite, os quais foram processados nos softwares Spring e ArcGis, bem como dados pluviométricos disponibilizados pela FUNCEME. Ressalta-se a importância da análise da cobertura vegetal no estudo de degradação. Com os mapas gerados, juntamente com os gráficos de pluviometria e de balanço hídrico, é nítido a supressão da cobertura vegetal na Serra da Meruoca-CE, isso porque mesmo no ano de 2013, com um balanço hídrico mais positivo que o ano de 1993, a resposta da cobertura vegetal foi inferior ao ano de 1993.Universidade Estadual de Londrina2015-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/2024710.5433/2447-1747.2015v24n1p91GEOGRAFIA (Londrina); v. 24 n. 1 (2015); 91-1052447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/20247/17369Copyright (c) 2015 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessLima, Denis BarbosaFreitas Filho, Manuel Rodrigues de2022-09-21T13:00:45Zoai:ojs.pkp.sfu.ca:article/20247Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-21T13:00:45Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
