| 摘要： | Abstract: A neighborhood-based planning approach is increasingly seen as an essential part of a comprehensive urban planning process. However, increasing the density of established neighborhoods may have negative impacts on neighborhood structure in regard to the issue of carrying capacity. The carrying capacity of a neighborhood may be examined under four components, including environment, infrastructure, urban public facilities, and socioeconomy. In this research, the carrying capacity issue has been examined in Tehran's established neighborhoods. The research method is quantitative and qualitative, using geo-spatial tools in Arc geographic information system (GIS) setting, the analytic hierarchy process method, interviews with experts, application of a Raster Analysis and GIS, and Point Density and Line Density. The collected indicators data were transformed through density analysis to Raster Layers. Then, the four selected components overlaid by "sum-weighted" regulations command obtaining the carrying capacity of the neighborhoods. The results showed that the carrying capacity potentials for the selected neighborhoods are less than the average score for all neighborhoods in Tehran. It can be said that the increasing density in established neighborhoods is quite different from new neighborhood developments. It may be possible only by considering a carrying capacity evaluation process. |
