摘要:O processo de desmatamento e o consequente aumento das áreas de pastagens configuram um dos graves processos de degradação das terras na atualidade. A presente pesquisa objetivou realizar análises multitemporais da cobertura vegetal (1980, 1990 e 2000) nos municípios de Canindé de São Francisco e Poço Redondo, com destaque para o Monumento Natural (MONA) Grota do Angico. Foram mapeadas seis classes: Caatinga arbórea, Caatinga arbórea-arbustiva, Caatinga arbustiva, Pasto, Hidrografia e Nuvens. O resultado mostrou o decréscimo das classes de Caatinga, como a variação da Caatinga arbórea entre o anos de 1980, 1990 e 2000 que corresponderam as porcentagens de 6,12, 0,71 e 2,81 respectivamente. Enquanto houve o consequente aumento da classe de pasto entre as referidas décadas, com 38,46, 52,33 e 69,65 respectivamente. A mesma lógica foi constatada dentro do MONA Grota do Angico.
其他摘要:The process of deforestation and the resulting increase in grazing areas constitute a serious land degradation process at present time. This research aimed to carry out multitemporals analysis of vegetation cover (1980, 1990 and 2000) in the municipalities of Canindé de São Francisco and Poço Redondo, with emphasis on the Natural Monument (MONA) Grota do Angico. Six classes of vegetation cover were mapped: arboreal Caatinga, arboreal-shrubby tree Caatinga, shrubby Savanna, pasture, hydrography and clouds. The result showed the decrease of the Caatinga, as arboreal Caatinga variation between the years 1980, 1990 and 2000 that matched the percentages of 6.12, and 0.71 2.81 respectively. While there was a consequent increase in the class of pasture between the referred decades, with percentages of 38, 46, 52,33 and 69,65 respectively. The same logic was established within the MONA Grota of Angico.
