Cambio en los patrones de crecimiento en una ciudad intermedia: el caso de Chillán en Chile Central Gerardo Azócar Rodrigo Sanhueza Estudios Territoriales SIG ciudad de Chillán crecimiento urbano índices espaciales Se identifican los patrones del crecimiento urbano de la ciudad de Chillán (ChileCentral), el uso del suelo asociado a cada uno de ellos y los factores que guían elproceso de expansión urbana. Se cuantificaron los cambios en la superficie urbanaconstruida en un período de 57 años (de 1943 hasta el 2000). Entre 1997 y el año2000, se analizó el cambio en relación con el uso del suelo, la densidad de poblacióny la condición socio-económica de los hogares. Se utilizaron fotografías aéreas,SIG (Arcview 3.2 y Arc-Info N.T) e índice de análisis espacial ( Spatially ExplicitLandscape Index). Un análisis de regresión permitió estudiar la relación entre crecimientourbano y crecimiento de población. 2003 artículo científico 0250-7161 https://www.redalyc.org/articulo.oa?id=19608706 es http://www.redalyc.org/revista.oa?id=196 EURE application/pdf Pontificia Universidad Católica de Chile EURE (Chile) Num.87 Vol.XXIX
