Abstract

Questo lavoro analizza la distribuzione spaziale dell?impermeabilizzazione del suolo in Italia attraverso un approccio esplorativo di statistica multivariata e analisi spaziale. Lo studio dimostra come semplici indicatori elaborati a scala locale possano fornire indicazioni per l?analisi territoriale e il monitoraggio ambientale. Sulla base di una cartografia ad alta risoluzione dell?uso del suolo, un "profilo di impermeabilizzazione" ? stato determinato per ciascun sistema locale del lavoro analizzando la distribuzione della superficie occupata da 12 classi di impermeabilizzazione progressiva utilizzando un'analisi delle componenti principali. Due indicatori di impermeabilizzazione del suolo sono stati sviluppati (intensit? di impermeabilizzazione e superficie sigillata pro-capite) nelle unit? spaziali indagate. I risultati suggeriscono che la distribuzione spaziale del tasso di impermeabilizzazione del suolo in Italia si discosta, almeno in parte, dalle dinamiche di popolazione che si riflettono nella distribuzione degli insediamenti urbani, mentre importante appare anche la struttura economico-produttiva nonch? il grado di infrastrutturazione complessiva del territorio. L?analisi mette in evidenza le differenze nella struttura territoriale degli insediamenti legata a diversi modelli urbani e riflette il passaggio da una forma poli-centrica e diffusa tipica della pianura padana a strutture tendenzialmente mono-centriche e pi? compatte nel Mezzogiorno. Analisi quantitative a elevata risoluzione spaziale come quelle proposte in questo articolo hanno implicazioni per le politiche di contenimento della diffusione urbana nell'ottica della sostenibilit?.
