Hill areas have gained considerable attention in recent years because of continuously increasing demand for infrastructure facilities. Spatial planning of infrastructure facilities is a challenging task in hill areas because of topographical variations, ecological sensitivity, and extreme climatic conditions. This becomes more critical because of the lack of an integrated quantitative approach for the assessment of land for its suitability. The paper aims at the spatial suitability assessment for planning infrastructure facilities at site level in hill areas. This has been accomplished in four stages; identification of the criteria, determination of weights of the criteria, spatial suitability assessment of the site, and scenario generation. In the first stage, a structured literature survey was done for the identification of the criteria influencing spatial planning of infrastructure facilities in the hill areas. In the second stage, an expert questionnaire survey was conducted for determining the percentage influence of the criteria and the responses were analysed through the analytical hierarchy process. In the third stage, spatial suitability map was generated in geographic information system for locating the infrastructure facilities. The vulnerability map was created for identifying the hazard prone areas. In the fourth stage, the developed suitability map and vulnerability map were aggregated to generate the scenario. A case study was taken for the implementation of the developed methodology which is useful for decision making for practitioners involved in the planning of infrastructure facilities in hill areas.

近年来，由于对基础设施的需求不断增加，丘陵地区引起了相当大的关注。由于地形变化，生态敏感性和极端气候条件，在丘陵地区，基础设施的空间规划是一项艰巨的任务。由于缺乏用于评估土地适宜性的综合定量方法，这一点变得尤为重要。本文旨在针对丘陵地区场地级别的基础设施进行规划的空间适宜性评估。这已分四个阶段完成；确定标准，确定标准权重，场地的空间适宜性评估以及方案生成。在第一阶段 为了确定影响山区基础设施设施空间规划的标准，进行了结构化文献调查。在第二阶段，进行了专家问卷调查，以确定标准的影响百分比，并通过层次分析法对答复进行了分析。在第三阶段，在地理信息系统中生成了空间适合性地图，用于定位基础设施。创建漏洞图是为了识别易发危险区域。在第四阶段，将开发的适用性图和漏洞图汇总起来以生成方案。
