Urban resilience to natural disasters has constantly been a challenge to sustainable development in human societies. Since Iran is always exposed to natural disasters such as earthquakes and floods, it is necessary to address novel approaches to deal with these disasters. The use of urban land and its characteristics in each city is one of the most important indicators related to urban resilience. The Manba Ab neighborhood is one of the most disorderly neighborhoods in Ahvaz city. Considering human perspective (inappropriate social construction), natural (adjacent to the only fault of Ahvaz city and the presence of unevenness in the area), physical and the built environment (improper proportions of land uses and road network; the proximity to large-scale industrial land uses) the city has an unsustainable condition that makes the resilience improvements in the area inevitable. This research aims to assess the resilience of the Manba Ab neighborhood against one of the most critical disasters, namely earthquakes. The paper is an applied descriptive-analytical, and collected data are analyzed in the GIS using algorithms in the ANP model, and Super Decision software. Obtained results show that about 45% of the Manba Ab neighborhood have low resilience against earthquakes due to fine-grained fabrics, low width of the passages, unsuitable building skeleton, deficiency in urban green spaces, and deficiency in relief services land uses. In this regard, land use planning is an essential tool in promoting earthquake resilience in neighborhoods. Identifying vulnerable areas of neighborhoods and reducing factors of neighborhood vulnerability can be very effective in earthquake resilience.

土地利用模式在抗震能力中的作用:Ahvaz Manba Ab 社区的案例研究

城市抵御自然灾害的能力一直是人类社会可持续发展的挑战。由于伊朗总是面临地震和洪水等自然灾害,因此有必要提出应对这些灾害的新方法。每个城市的城市土地利用及其特征是与城市韧性相关的最重要指标之一。Manba Ab 街区是阿瓦士市最混乱的街区之一。考虑人的视角(不适当的社会建设)、自然(毗邻阿瓦士市的唯一断层以及该地区存在的不平坦)、物理和建筑环境(土地利用和道路网络的比例不当;靠近大规模工业用地)该市处于不可持续的状况,这使得该地区的复原力改善不可避免。这项研究旨在评估 Manba Ab 社区对最严重的灾害之一(即地震)的恢复能力。该论文是一篇应用描述性分析论文,使用 ANP 模型中的算法和 Super Decision 软件在 GIS 中分析收集的数据。结果表明,由于质地细密、通道宽度小、建筑骨架不合适、城市绿地不足、救灾服务用地不足等原因,曼巴阿布社区约45%的地区抗震能力较差。在这方面,土地利用规划是提高社区抗震能力的重要工具。
