AMBIENTAL FRAGILITY MEASSUREMENT: A NEW METHODOLOGY TO CONSERVATIONIST UNITIES OF INDIRECT USAGE ON URBAN FORESTS.

This paper presents a new methodological approach to make possible the environmental fragility evaluation, considering human interferences on primitive or no primitive ecosystems purposed to became urban protected areas. This innovatory approach, is based in traditional models that use landscape quality evaluation and environmental impact assessments, but makes possible the establishment of specific evaluation criteria to each environmental factor and their integration.

Key words:
environmental fragility; environmental evaluation; urban ecology; protected areas
