In this article, we present a geographically explicit agent-based model (ABM), loosely coupled with vector geographical information systems (GISs), which explicitly captures and uses geometric data and socioeconomic attributes in the simulation process. The ability to represent the urban environment as a series of points, lines, and polygons not only allows one to represent a range of different-sized features such as buildings or larger areas portrayed as the urban environment but is a move away from many ABMs utilizing GIS that are rooted in grid-based structures. We apply this model to the study of residential segregation, specifically creating a Schelling (1971) type of model within a hypothetical cityscape, thus demonstrating how this approach can be used for linking vector-based GIS and agent-based modeling. A selection of simulation experiments are presented, highlighting the inner workings of the model and how aggregate patterns of segregation can emerge from the mild tastes and preferences of individual agents interacting locally over time. Furthermore, the article suggests how this model could be extended and demonstrates the importance of explicit geographical space in the modeling process. 相似文献

ABSTRACT. In Lindsborg, Kansas—“Little Sweden, U.S.A.”—the streets are lined with shops offering “An Adventure in Swedish Tradition,” and residents put on numerous festivals throughout the year highlighting Swedish folk customs. Such ethnic tourist towns have become increasingly widespread in the United States over the past thirty years. Tourists tend to perceive these places as towns where folk culture has been passed down unchanged for generations, while academics tend to dismiss residents' ethnicity as crass commercialism. Neither view is correct. Ethnicity and tradition are not static but constantly invented and reinvented. Modern folk ethnicity, among European Americans in particular, is simply the most recent incarnation of this process, one that attempts to recover ties to a specific, small‐scale landscape and history. This article explores the changing nature of the narratives of ethnicity and place‐based identity that the residents of Lindsborg have used to create a place for themselves in American society. 相似文献
