Abstract Urban land suitability analysis is a complex process that requires geo-physical and environmental information and relevant expertise to analyse and interpret the information. This paper focuses on the integration of geographic information systems (GIS) and multi-criteria decision analysis (MCA) for the assessment of potential suitability of urban development in Pendik district located in eastern Istanbul, Turkey. Various factors, including geo-physical attributes, accessibility, built-up area and infrastructure, vegetation, and green and blue amenities, were used for the land-use suitability assessments. Two different approaches (a deterministic and a fuzzy modelling approach) were utilised to evaluate the suitability of land uses for residential, industrial/commercial and recreational developments. Standardisation of values and unification of scales in map layers were done using the traditional deterministic approach in the first model, whereas fuzzy logic was used in the second model for the same purpose. AHP weighted the sub-criteria in the first model, and the fuzzy AHP method was used in the second model. The map layers were overlaid using the weighted linear combination for both cases using the GIS software. The final stage of the suitability assessment process consisted of a sensitivity analysis of the selected factors and their associated weights. The integration of fuzzy logic, fuzzy AHP and GIS is an advanced methodology and can improve suitability evaluations compared with those of alternatives based on traditional approaches. From our findings, we note that suitable lands for urban development are mainly located in the central and southern parts of the case study area. Our results also highlight how the spatial distribution of suitability classes vary with the selected model utilised for suitability assessment. The methodologies described in the paper can be extended to similar contexts, both locally and internationally.

土耳其伊斯坦布尔彭迪克区城市建设用地适宜性评价

摘要 城市土地适宜性分析是一个复杂的过程，需要地球物理和环境信息以及相关专业知识来分析和解释信息。本文侧重于地理信息系统 (GIS) 和多标准决策分析 (MCA) 的集成，以评估土耳其伊斯坦布尔东部彭迪克区城市发展的潜在适宜性。土地利用适宜性评估使用了各种因素，包括地球物理属性、可达性、建成区和基础设施、植被以及绿色和蓝色设施。两种不同的方法（确定性和模糊建模方法）被用来评估土地利用对住宅、工业/商业和娱乐开发的适宜性。地图层中值的标准化和比例尺的统一在第一个模型中使用传统的确定性方法完成，而在第二个模型中使用模糊逻辑实现相同目的。AHP 对第一个模型中的子标准进行加权，而在第二个模型中使用模糊 AHP 方法。使用 GIS 软件对两种情况使用加权线性组合叠加地图图层。适宜性评估过程的最后阶段包括对选定因素及其相关权重的敏感性分析。模糊逻辑、模糊层次分析法和 GIS 的集成是一种先进的方法，与基于传统方法的替代方法相比，可以提高适宜性评价。从我们的调查结果来看，我们注意到适合城市发展的土地主要位于案例研究区的中部和南部。我们的结果还强调了适宜性类别的空间分布如何随用于适宜性评估的选定模型而变化。论文中描述的方法可以扩展到类似的环境，包括本地和国际。
