Urban Green Areas System, Ecosystem Planning, Ecosystem Services, Urban Instruments
There are lost links between nature and man that have been building throughout history, making people more dominating than partners of nature (THOMAS, 1989). In cities, it is observed the disregard of ecological characteristics to locate green areas with prevalence of the relationships between densities and presence of these spaces that have emphasis on the function of social integration (BEZERRA et al, 2016). These areas are routinely decorative spaces and accessories that contribute little to the preservation of the ecosystem and/or the provision of environmental services (SPIRN, 1995). In view of this problem and identified the gap in the discussion of an ecologically based urban green areas system (UGAS), the research aims to establish criteria of an ecosystem and urban nature for the implementation of urban green areas systems, as well as urban-environmental instruments that favor its implementation and management. It states that the need to renaturalize cities finds in the landscape ecology bases to define the criteria that should support the studies of an ecological UGAS such as: connectivity, multifunctionality multiscale, interdisciplinarity, social participation, promotion of biodiversity and permeability. It studies the environmental and urban normative bases of several Brazilian cities, allowing the identification of cities with UGAS’s with some degree of implementation (especially São Paulo and Campinas), as well as environmental and urban instruments that can support the implementation of a UGAS. It verifies through the landscape metrics method the UGAS's of these cities regarding the applicability of the defined criteria and finally, presents the technical procedures to be performed for the structuring of an ecological-based UGAS with potential for the provision of urban ecosystem services.
