"Recent developments of sociological theory are paying increasing attention to space as a cathegory of analysis.The concepts of centre and pheriphery, border, urban-rural settlement,town village etc. refer not only to different social organization processes,but also to their spatial basis. On the other hand they reflect the way social,political, cultural, ethnic, etc. factors organize space.In Italy spatial-oriented sociology has an importan and long standing tradi-tion, though different labels (and approaches) are attributed to the study ofthe links between space and society.Proceeding from spatial-oriented socilology in recent years empirical re-search has been directed towards the study of territorial identity."To be a member of", "the sense of belonging" is one of key concepts to un-derstand the behavior of social actor, his identity, his position inside socie-ty etc.The social actor is not only a member of a group, of an organization, a na-tion etc. but also a member of a territorial community. Under what condi-tions the space, the environment where people live, become a relevent ele-ment for the development of individual identity? What kind of relations exisbetween social and spatial belonging?The process of modernization, the development of-new communication technologies are reducing the particular features of local territorial communities. Starting from these basic questions the aim of the paper is to present theresults of a survey on socio-spatial patterns of community attachment.The data analyzed are derived from a questionnaire survey carried out in1986 on a large area sample of residents (1500) in four regions in theNorth-Eastern Italy. For each region the sample include residents of moun-tain, rural, urban and coast settlement.The paper analyzes the regional sub-sample of Friuli compared with theother regional samples.The central dependent dimension explored by the study is the socio-spatialattachment to community. This refers to the subjective sense of attachmentto a place, a space, that are characterized by: a) the existence or not of asense of attachment of some place; b) if yes : 1) geographical extension(from the local community through middle levels to higher levels: the wholeworld) (localism- universalism); 2) strength of tie; 3) type of attachment(motivations expressed by the subject and recognized as important for his/her tie with place).The independent dimensions analyzed are: ecological charactrisics of settle-ments, level of residential mobility/stability of the sample; social integra-tion; psychocultural features of individuals.The first part of the study resumes th theoretical background of the re-search.The second part presents the main resuts of the survey:a) defining patterns of territorial identity (through a multivariate model ofanalysis); b) analyzing an explicative model (through multiple regressionanalysis) of different patterns of attachment.The results support the strong influence of "ecological" variables on papt-terns of socio-spatial attachment. Residential stability increases socio-spatial identity acting indirectly through the integration in the social net-work."
