Scattered or polycentric? Untangling urban growthin three southern European metropolitan regionsthrough exploratory spatial data analysis
时间:2017-04-16

【摘要】The present study illustrates an exploratory spatial data analysis (ESDA)aimed at investigating changes in the distribution of built-up areas in three southernEuropean metropolitan regions (Barcelona; Rome and Athens). An approach based onglobal Moran’s indexes of spatial autocorrelations was proposed to assess similaritiesin the spatial organization of the three regions; based on land-use data for 1960 and2010. Compact monocentric; scattered low-density and mixed polycentric structureswere compared in the three regions using local Moran’s indexes computed at twodifferent scales; “urban” (5km radius) and “regional” (20km radius). The proposedapproach identifies emerging trends in scattered monocentric or polycentric development.Our results outline the trend toward scattered urban expansion for the threecities; with signs of a modest shift toward polycentrism in Barcelona. ESDA providesbasic information needed for policies promoting spatially balanced; sustainabledevelopment in originally compact and economically segmented regions.
