| Summary: | Considering the current situation of the loss of natural vegetation cover, due to the advancement of agribusiness frontiers, are essential studies with approaches that consider spatial and temporal cuts in order to monitor the advance of deforestation. Therefore, this researchhas the objective undertake an assessment of deforestation of the natural vegetation in the area of the upper course of the Rio Pardo, Midwestern state of Sao Paulo, for a period of approximately 35 years from 1976 to 2011, with the aim to represent through mappings, the loss of natural vegetation cover during this period, through techniques of GIS and Remote Sensing products. To develop this study, was used orbital images ofthe Landsat satellite 5 TM sensor (images of 1985 to 2011) and Landsat 2, MSS sensor, (images of 1976), which were processed in the GIS Idrisi Taiga and AcrGIS 9.3, in order to compare the mappings to the different times and thereby to analyze the changesin this natural resource. To this end, with such analysis could confirm a significant natural vegetation cover's loss between 1976 and 2011, which is in the range of 10 years from 1976 to 1985, first analysis period, this loss was approximately 10,5%, while for the range of 26 years from 1985 to 2011, was 32,4%. Considerando a atual situação da perda da cobertura vegetal natural, em função do avanço das fronteiras agropecuárias, tornam-se necessários estudos com abordagens que considerem recortes espaciais e temporais com o intuito de monitorara avanço de desmatamentos. Portanto,esta Pesquisa tem por objetivo realizar uma avaliação do desmatamento da vegetação natural na área do alto curso do Rio Pardo, Centro-Oeste do Estado de São Paulo, para um período de 35 anos, de 1976 e 2011, com a finalidade de representar através de mapeamentos, a perdada cobertura vegetal natural no decorrer deste período, por meio de técnicas de Geoprocessamento e produtos de Sensoriamento Remoto. Para o desenvolvimento deste trabalho, foram utilizadas imagens orbitais do satélite Landsat ... |
