Résumé

Como em muitos outros países, as medidas oficiais de urbanização no Brasil não puderam distinguir adequadamente os padrões espaciais de organização rural e urbana. A literatura discute vários sistemas de classificação e reconhece a existência de um “continuum rural-urbano”, assim como marcos teóricos e categorizações alternativas com o objetivo de superar a dicotomia urbano-rural. No entanto, não existem soluções práticas que os formalizem e operacionalizem adequadamente, especialmente no nível micro, como as seções censuradas. Propomos uma metodologia que pressupõe um contínuo rural-urbano médio. O “Índice de Gradiente Urbano” utiliza variáveis ​​simples e ampliadas para quantificar o grau em que uma determinada área é urbana em função de características demográficas e espaciais. Eles construíram um nível de seções censuradas para o Brasil e a Região Metropolitana de Belo Horizonte para verificar a consistência entre os diferentes níveis de agregação. Os resultados indicam que o índice fornece uma imagem muito mais matizada dos padrões de assentamento, revelando um gradiente espacial entre o rural e o urbano em extensões espaciais distintas. Oferece uma venda sobre a medida tradicional de “grau de urbanização” para revelar “ruralidades ocultas” em áreas predominantemente urbanas que requerem intervenções específicas de planejamento territorial e políticas públicas.

Palavras-chave : Gradiente Urbano, Continuum Rural-Urbano, Planificação Territorial, Região Metropolitana de Belo Horizonte, Brasil.
