Le città raffigurano i luoghi in cui si concentrano flussi di persone, di beni e di informazioni e, pur differenziandosi per la posizione, la dimensione e, in particolare, per le loro funzioni, rimangono, nel tempo e con un sempre più intricato sistema di nodi e di maglie, le principali protagoniste dello sviluppo locale, nazionale ed internazionale. Ogni città, per quanto rappresentata dal suo centro “storico”, uno spazio che non sempre nei processi evolutivi urbani ha mantenuto il suo ruolo di luogo centrale principale, ha visto, nel suo interno svilupparsi, poi, altre zone che tendono a disporsi, specializzarsi e concentrarsi in modo funzionale: quartieri caratterizzati, quindi, da una o più funzioni dominanti siano esse commerciali, amministrative, residenziali, culturali. Partendo dalla definizione del Central Business District (CBD) o “luogo centrale” della città e mantenendo come riferimento gli “ambiti urbanistici”o “quartieri” dell’ultimo Piano Urbanistico Comunale della città di Sassari, si è passati all’analisi quantitativa e distributiva delle attività urbane di rango superiore dell’intero territorio comunale. Il computo di alcuni indicatori delle stesse in relazione sia alla lunghezza delle strade di loro pertinenza, sia al numero di residenti di ogni ambito urbano di riferimento, ha evidenziato come queste attività occupino, per più dei quattro quinti, la città compatta e si concentrino, significativamente, in quattro dei trentadue quartieri che la costituiscono. Le rappresentazioni iconografiche, elaborate su di una mappa georeferenziata, permettono di visualizzare questa area centrale (CBD) e di individuare in essa un core, Piazza d’Italia, dove ad una maggiore intensità delle attività rare fa riscontro un ridotto numero di residenti.

Abstract
The cities represent the places where concentrate the streams of people, assets, informations and, even if they differ in position, dimension and, in particular, in their functions, they remain, in the long run, and with a system of knots and links, more and more intricate, the main protagonists of the local, national and international development. Every city, even if represented by its "historic centre" (space that not always has maintained its role of principal central position in the urban evolutionary processes), has seen, in its interior, to develop further areas tending to place themselves, to specialize and to concentrate in a functional way: therefore districts marked by one or more dominant functions, commercial, administrative, residential, cultural. Starting from the definition of the Central Business District (CBD) or "central place" of the city and keeping as reference the "urban environments" or "districts" of the last town-planning project of the city of Sassari, we have proceeded to the quantitative and distributive analysis of the urban activities of upper level of the whole city's territory. The calculation of some indicators of the above activities in connection both with the lenghth of the roads of their pertinence and the number of residents of every urban environment of reference, has highlighted the fact that such activities refer, for more than four fifths, to the close city and concentrate, significantly, in four only of the thirty-two districts forming it. The iconographic representations, drawn-up on a georeferenced map, allow to visualize this central area (CBD) and to locate a core, Piazza d’Italia, where a reduced number of residents corresponds to a greater intensity of rare activities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
