Abstract(s)
O presente estudo analisa a evolução da paisagem, ao nível do uso e ocupação do solo no concelho de Condeixa a Nova, localizado, na região Centro e sub-região Região de Coimbra. Com o auxílio de software, como o ARCMAP e FRAGSTATS, foi possível avaliar a configuração da paisagem bem como a sua evolução ao longo dos vinte anos que decorreram entre 1995 e 2015. A metodologia utilizada consistiu na caracterização da área de estudo, criação de mapas, e avaliação da paisagem.Os resultados obtidos apontam para evolução ao nível dos domínios de uso dos solos impulsionados a partir do ano de 1995 pelo abandono da agricultura que levou a conversão dessas áreas em Matos, Floresta, e domínio Urbano. Já ao nível da ocupação dos solos assistiu-se a um progressivo abandono da cultura de Pinheiro bravo e a sua consequente substituição por outras espécies como o Eucalipto e o Pinheiro manso. Tais alterações tiveram como consequência uma elevada fragmentação da paisagem. Por ultimo executou-se um exercício de elaboração de corredores ecológicos, que permitiu entre outras chegar a conclusão que o traçado dos corredores ecológicos que constam do PROF do Centro Litoral, esta erradamente delineado o que leva a impossibilidade da sua aplicação pratica no terreno.
This study analyzes the evolution of the landscape, in terms of land use and occupation in the municipality of Condeixa a nova, located in the Center region and the Region of Coimbra sub-region. With the aid of software, such as ARCMAP and FRAGSTATS, it was possible to evaluate the landscape configuration as well as its evolution over the twenty years between 1995 and 2015. The methodology used consisted of characterizing the study area, creating maps, and evaluation of the landscape.The results obtained point to an evolution at the level of land use domains driven since 1995 by the abandonment of agriculture that led to the conversion of these areas into Bush, Forest, and Urban domain. In terms of land use, there was a progressive abandonment of the maritime pine culture and its consequent replacement by other species such as Eucalyptus and pine. Such changes resulted in a high fragmentation of the landscape. Finally, an exercise in the elaboration of ecological corridors was carried out, which allowed, among others, to conclude that the layout of the ecological corridors contained in the PROF of the Centro Litoral, is wrongly delineated, which makes it impossible to apply it in practice on the ground.
