-With the objective of promoting nature conservation, this study proposes an environmental zoning for a protected area that contains part of the remaining Atlantic Forest, a global hotspot that is home to several endangered species of flora and fauna. Conflicting therewith, the protected area is an important tourist attraction in the region and receives many visitors throughout the year. For the zoning preparation, the main factors and constraints of each objective (ecotourism and conservation) are established, and a multicriteria analysis is used, in addition to the MOLA (Multi-Objective Land Allocation) algorithm, to establish the most suitable areas for each use. Extreme protection areas are defined through the intersection of endemic vegetation and soils and altitudes above 1,500 m. Thus, a fraction of 18% is obtained for extreme protection, 59% for conservation, and 23% for areas destined for ecotourism development. The results demonstrate the advantages of using these methods, due to their simplicity, which can support administrators in planning the protected area. The zoning is in accordance with the International Union for Conservation of Nature (IUCN) recommendation because the conservation area corresponds to approximately 77% of the park area, reinforcing the suitability and applicability of the methodology that is used for the zoning of a protected area.Keywords: GIS; Preservation area; Zoning. DEFINIÇÃO DE ZONAS PRIORITÁRIAS PARA A CONSERVAÇÃO E ECOTURISMO EM UMA ÁREA PROTEGIDARESUMO -Neste trabalho foi proposto um zoneamento para uma área protegida, que tem como missão a conservação da natureza e contém parte da Mata Atlântica residual, um hotspot mundial, que abriga diversas espécies da fauna e flora ameaçadas de extinção. Conflitando-se a esse uso, a área protegida é um importante atrativo turístico da região e recebe muitos visitantes ao longo do ano. Para a elaboração do zoneamento, foram estabelecidos os principais fatores e restrições de cada objetivo (ecoturismo e conservação) e utilizouse de uma análise multicritério e do algoritmo MOLA (Multi-Objective Land Allocation) para estabelecer as áreas mais adequadas a cada uso. Foram estipuladas áreas de proteção extrema, através de uma interseção entre solos e vegetação endêmicas e altitudes superiores a 1500 m. Assim, obteve-se uma fração de 18% para as áreas destinadas a proteção extrema, 59% para a conservação e 23% para as destinadas ao desenvolvimento do ecoturismo. Os resultados explicitaram as vantagens da utilização desses métodos dada a sua simplicidade, podendo auxiliar os gestores no planejamento da área protegida. O zoneamento obtido está de acordo com a recomendação da IUCN, visto que a área de conservação correspondeu à aproximadamente 77% da área do parque, reforçando a adequabilidade e aplicabilidade da metodologia empregada para o objetivo de zoneamento de área protegidas.Palavras-chave: SIG; Área de preservação; Zoneamento.

a b s t r a c tIn this study, biomass production and domestic sewage treatment in hybrid systems under bacterialmicroalga consortia were assessed. Biomass was grown suspended in the growth media of high-rate ponds (HRPs) and attached in biofilm reactors (BRs). These hybrid systems were operated with and without the addition of CO 2 (HS2 and HS1, respectively) in the HRP growth media. The performances of these systems were compared with that of a conventional HRP with CO 2 supplementation. Regarding sewage treatment with microalgae and bacteria consortia, the three systems showed no significant differences in the removal of organisms associated with faecal contamination, organic matter and most nutrients. However, nitrate levels were increased in the hybrid systems due to the presence of BRs. There were no differences in algal biomass production among the three systems, which remained in the 0.6-0.7 g m −2 range. HS1 showed the highest total biomass production of 101.31 g m −2 at a production rate of 6.79 g m −2 day −1 . The BR of HS1 was able to supply the necessary CO 2 and therefore no additional gas supplementation was required. This result indicates that a conventional HRP with CO 2 supplementation can be replaced by a hybrid system with biofilm reactor, with additional advantages of resources saving, operational simplicity and easier harvesting.
