The urban environment is where an increasing share of the world’s population resides, where the most commercial energy is consumed, and where the impacts of pollution are imposed the most. In the urban environment, because of its complex structure, the air pollution appears unpredictable covering narrow area. The AirScope system is developed for that kind of micro-scale air pollution management...
Urban land use spatial layout model research has been suffered from static model to dynamical model. The traditional model and theory like static, macroscopic or determinate model sometimes made the urbanize land use change immoderate simplify. The non-linear effect of microcosmic and macroscopical urban agent were embodied in the decision-making process of urban land use planning. In this pape...

Urban fabric characterization is very useful in urban design, planning, modeling and simulation. It is traditionally considered as a descriptive task mainly based on visual inspection of urban plans. Cartographic databases and geographic information systems (GIS) capabilities make possible the analytical formalization of this issue. This paper proposes a renewed approach to characterize urban f...
