نبذة مختصرة : The conversion from Forest to other kinds of alternative land uses has been occurred rapidly in the Amazon region. This process has been occurred mostly due to the development of the cattle ranching, large scale and familiar agriculture, commercial timber and mining.

Thereby, this research tried to evaluate the capacity of such legal reserves to ensure the conservation of natural resources, making use of the CAR data and other products of governmental agencies researches. Two Amazon basins were evaluate through principles of landscape ecology with the use of landscape metrics. The results indicate that the two study areas have different characteristics, one having more capacity to maintain the resources and other markedly more fragmented, indicating also different characteristics of rural properties with different importance to the conservation of the natural resources. ; A conversão de floresta primária para outros usos alternativos do solo vem ocorrendo aceleradamente na região amazônica. Esse processo tem ocorrido em grande parte por conta do desenvolvimento da atividade pecuarista, agricultura em larga escala e de subsistência, exploração madeireira comercial e mineração. Nesse contexto, a fim de promover a conservação dos recursos naturais, o Governo brasileiro adotou o sistema de unidades de conservação, terras indígenas e quilombolas. Além disso, foram criados instrumentos como o Cadastro Ambiental Rural – CAR objetivando mapear e monitorar as propriedades rurais quanto ao atendimento do disposto no Código Florestal ...
