Over the recent years, urban green infrastructure (UGI) modelling has emerged as an adaptation strategy to enhance cities' resilience against ever-rising environmental hazards. The UGI improves urban eco-system functions to protect human health and wellbeing, both locally and globally. Pakistan lacks inclusive and resilient land-use planning policies as well as frameworks to protect its inhabitants, and ecosystems from the rising climatic hazards. So, this research aims to determine and assemble sustainable UGI planning indicators based on local stakeholder's perspectives. It is to develop a comprehensive and integrative indicator-based framework model to build climate-resilient urban regions in Pakistan's northwest parts. The in-depth online expert's survey is administered through 172 questionnaires themed around UGI, urban resilience and climate change adaptation. The data is analysed by using Relative Importance Index (RII) and Interquartile Range Technique (IQR). The finding shows potential twenty-two (primary and secondary) sustainable UGI indicators, classified into three main categories; Extremely Important (E-Imp); Important (Imp) and Moderately important (M-Imp) levels. Subsequently, a set of vital green elements that achieved (RII value ≥ 0.76) were identified that upgraded and strengthened each UGI indicator's quality. Additionally, it helps to reinforce an intricate connection among climate resilience strategies, green spaces, ecosystem functions, and human health/wellbeing in the study region. The UGI model facilitates policy planning and decision-making process for resilient land use planning and urban sustainability.

用于规划巴基斯坦弹性城市住区的绿色基础设施指标:当地利益相关者的观点

近年来,城市绿色基础设施 (UGI) 建模已成为一种适应策略,以增强城市对不断增加的环境危害的抵御能力。UGI 改善了城市生态系统功能,以保护当地和全球的人类健康和福祉。巴基斯坦缺乏包容性和弹性的土地利用规划政策以及保护其居民和生态系统免受不断上升的气候危害的框架。因此,本研究旨在根据当地利益相关者的观点确定和组合可持续的 UGI 规划指标。将开发一个全面的、综合的、基于指标的框架模型,以在巴基斯坦西北部建设气候适应型城市地区。深入的在线专家调查通过 172 份以 UGI 为主题的问卷进行管理,城市复原力和气候变化适应。使用相对重要性指数 (RII) 和四分位距技术 (IQR) 分析数据。调查结果显示了潜在的 22 个(主要和次要)可持续 UGI 指标,分为三个主要类别;极其重要(E- Imp); 重要 (Imp) 和中等重要 (M-Imp) 级别。随后,确定了一组实现(RII 值≥ 0.76)的重要绿色元素,升级和加强了每个 UGI 指标的质量。此外,它还有助于加强研究区域气候复原力战略、绿色空间、生态系统功能和人类健康/福祉之间的错综复杂的联系。UGI 模型促进了弹性土地利用规划和城市可持续性的政策规划和决策过程。
