- W1799463118 abstract "A apropriação do meio natural pelo homem estabelece estratégias próprias de produção e organização espacial. O presente trabalho possui como objetivo realizar uma análise multitemporal do uso e da cobertura da terra nas últimas duas décadas no município de Riachão das Neves, considerando as unidades geomorfológicas e as adequações às leis ambientais. Com este propósito, a metodologia adota técnicas de geoprocessamento validadas por trabalho de campo. O processamento dos dados pode ser subdividido nas seguintes etapas: (a) análise multitemporal do avanço agrícola, (b) delimitação das Áreas de Proteção Permanente (APP), e (c) identificação do uso inadequado das áreas protegidas por lei. A análise multitemporal utiliza-se de imagens de alta resolução espacial do sensor ALOS-PRISM referente ao ano de 2008 e uma série temporal de imagens do sensor LANDSAT referente aos anos 1988, 1992, 1996, 2000, 2004 e 2008. Riachão das Neves ainda possui aproximadamente 67% de área de vegetação natural. Existe um nítido controle geomorfológico no sistema de produção. Nas áreas de Depressão e Vale o uso está concentrado próximo aos rios pelos pequenos proprietários de terra, em sua maioria pecuaristas, enquanto que em áreas de Chapada o uso da terra está dominado pela agricultura mecanizada de grande escala.
 
 Abstract 
 
 LAND USE EVOLUTION AND GEOMORPHOLOGICAL UNIT RELATIONSHIP IN RIACHÃO DAS NEVES COUNTY (BA): EFFECTS IN PROTECTED AREAS
 
 The appropriation of the natural environment by man establishes strategies of spatial production and organization. This work aims to perform a multitemporal analysis of land use and land cover in the last two decades in Riachão das Neves County, considering the terrain attributes and the adequacy of environmental laws. The methodology adopts remote sensing and GIS techniques and field work. The data processing can be subdivided into the following steps: (a) multitemporal analysis of agricultural expansion, (b) protected areas mapping, and (c) identification of inappropriate use of protected areas. Multitemporal analysis using ALOS-PRISM sensor with high spatial resolution for 2008 and the Landsat imagery from 1988, 1992, 1996, 2000, 2004 and 2008. The classification process was done by visual interpretation and checking of field work. Riachão das Neves has approximately 67% of the natural vegetation. There is an apparent geomorphological control on the production system. In the Depression and Valley areas, the land use is concentrated around the rivers by small farmers, mostly livestock farming, while in the Plateau areas the land use is dominated by large scale mechanized agriculture." @default.
