A estrutura ecológica e os planos regionais de ordenamento do território. Caso de estudo - Área metropolitana de Lisboa

Mestrado em Arquitectura Paisagista - Instituto Superior de AgronomiaThe delimitation at different scales of the Ecological Network is established by the Decree-Law nº 380/99. However, it does not define which components should be integrated in Ecological Network. The concept of Ecological Network varies from national to local scale. As an example, the Decree-Law nº 380/99 established that the Regional Land Use Plans should propose Environmental Protection and Valorization Regional Structures (EPVRS). In this way, it becomes important to create a coherent Ecological Network concept at the various planning scales. In order to contribute to this aim, this paper attempts to demonstrate which components should be considered at the regional scale. As a consequence, this paper develops a comparison between the EPVRS elaborated in Regional Land Use Plans: Norte, Centro, Oeste e Vale do Tejo, Área Metropolitana de Lisboa, Alentejo e Algarve. Concerning each EPVRS the following matters were analyzed: methodology; components; EPVRS representation at the Territorial Development Model; EPVRS translation into the municipal level. This paper also proposes an approach to the ecological network to Lisbon Metropolitan Area, based on the ―Sistema-Paisagem‖ methodology. Finally, it presents a comparison between the Ecological Network and the EPVRS proposed in the Regional Land Use Plan of the Lisbon Metropolitan Area
