Resumo
Instituídos a partir dos anos 80 do século passado, os Planos Directores Municipais constituem o principal instrumento de ordenamento do território à escala local.
Um dos principais objectivos destes instrumentos de gestão do território é o do controlo da dispersão urbana. Ou seja, a contenção das edificações nos perímetros urbanos classificados como tal, evitando assim as consequências nefastas de uma expansão urbana descontrolada.
Esta dissertação procura analisar em que medida estes planos cumpriram esse objectivo, através da análise de um caso de estudo, o do concelho de Alijó no alto Douro Vinhateiro.
O estudo com recurso ao SIG, baseando-se numa análise das dinâmicas de edificação urbana, entre 1995 e 2005.
Os resultados obtidos demonstram que estes instrumentos estão longe de conseguirem eficazmente este objectivo, sendo necessário proceder a alterações substanciais no regulamento destes planos e até numa abordagem teórica e empíricas do processo de planeamento territorial em Portugal.
Established in the eighties of the past century, Director Municipal Plans constitute the main instrument of local scale territory planning. One of the main objectives of these instruments of territory management is the control of the urban sprawl. In other words, keeping the buildings in the urban perimeters classified as such, avoiding the fatal consequences of an uncontrolled urban expansion. This dissertation seeks to analyze in what measure these plans fulfilled that objective, through the analysis of the case study of the council of Alijó in the Douro wine country. The study with resource to the SIG was based in an analysis of the dynamics of urban edification, between 1995 and 2005. The results that we have obtained from this study show that these instruments are far from reaching their objective, being necessary to start making important changes in the regulations of these plans and even in the theoretic and empiric approach of the land planning process in Portugal.
