Aplicação do processo analítico Hierárquico na construção de um sistema fuzzy de apoio ao planejamento do uso futuro na recuperação de áreas degradadas: Estudo de uma cava mineral na Serra do Japi

Abstract

The definition of use future is fundamental to land reclamation. However, the selection among alternatives requires an integrated assessment through a structured and logic process. Thus, the aim of this paper is introduce a proposal to support the planning of future use, applied in a deactivated pit mining, in Serra do Japi, Jundiaí city, São Paulo state, Brazil. For that, a Fuzzy Inference System was elaborated, whose rule base was constructed from Analytic Hierarchy Process. Considering its relevance to self-sustainability, the forest connectivity, the area extension and the edge effect were selected as analysis criteria and the outputs being modeled as use recommendations, represented by revegetation and re-destination. As results, based on evaluated condition, its application in the study area recommended the revegetation, predominating influence of its good forest connectivity. Although, being a relatively small area and with a significant edge effect, the system pointed out a low confidence level in this recommendation. Therefore, it was considered a coherent output with the expected and a satisfactory reference to the decision maker accept or deny the recommendation given by the support system.
