建设和改善城市住区是整个城市发展过程中一个永恒的关键课题，它涉及到一系列的挑战和问题。在过去的几十年里，随着城市人口的大量流动，城市住宅的发展速度大大加快。本研究的目的是提出一种综合考虑可持续性指标、住房均衡和建筑可视化的城市住宅发展可持续性评价方法。首先，在融合DPSIR （Driving Forces, Pressure, State, Impact and Response）框架和层次分析法（AHP）的基础上，对指标进行了系统化的可持续性建模。由于城市活动的影响不仅局限于局部层面，而且具有更大的尺度，因此采用系统动力学（SD）方法构建了模拟模型，对指标的发展趋势进行了定量研究。然后在ArcGIS的二维密度图和CityEngine的三维可视化中显示估算结果。为德国南部巴登-符腾堡州的斯图加特地区及其Plieningen地区提供了一个真实的案例研究，以体验所开发方法的有效性和可行性。GIS、SD模型和三维可视化的结合，这里称之为GISSD系统，可以更好地解释住宅开发可持续发展指标的相互作用和变化。从而能够支持决策者更全面地看待城市住区的可持续发展水平。(C) 2011 Elsevier Ltd.版权所有。
Constructing and improving urban residential areas is an eternal critical subject in the process of the whole urban development which is connected with a series of challenges and problems. During the past decades, urban residential development has speed up extremely with massive population mobility in cities. The purpose of this study is to propose an integrated approach for sustainability assessment of urban residential development, considering sustainability indicators, housing equilibrium and building visualization. Firstly based on merging DPSIR (Driving Forces, Pressure, State, Impact and Response) framework and Analytic Hierarchy Process (AHP), the indicators were systematized for the sustainability modeling. Due to the urban activities cause impacts not only on local level but also a broader scale, a simulation model, using System Dynamics (SD) methodology, was structured to quantitatively investigate the developmental tendency of the indicators. And then the estimated results were displayed in 2D density maps in ArcGIS and 3D visualization in CityEngine. A real case study was presented for the Stuttgart Region of the state of Baden-Wurttemberg in Southern Germany and its Plieningen district to experience the usefulness and feasibility of the developed approach. The integration of GIS, SD model and 3D visualization, called GISSD system here, can better explain the interaction and the variation of the sustainability indicators for residential development. Hence it is able to support the Decision Maker to view the sustainable level of urban residential areas more comprehensively. (C) 2011 Elsevier Ltd. All rights reserved.
