Urban expansion has been rapidly increasing and is projected to be tripled in 2030 in worldwide. The impact of urbanization has adverse effects on the environment and economic development. Residential lands consist of almost one-third of the urban area and heavily affect the city's inhabitants. The capital of Mongolia, Ulaanbaatar, has been significantly expanded, particularly in the urban periphery where poor living conditions and a lack of essential urban services were identified. The paper aims to conduct a suitability analysis of residential areas in Ulaanbaatar city based on three main categories (livability, affordability, and accessibility) of fifteen criteria using the fuzzy logic. Through the study, we have identified some potential suitable residential areas for further development, such as apartment residential area located in the southern part of the city and four low-rise ger areas were distributed along major transport corridors. Moreover, the results indicated that the spatial structure of the whole town might be in transition to a polycentric pattern. However, a concentric ring pattern in the 'city's periphery displayed a concerning uncontrolled ger area expansion, which may increase low living conditions in the area. This study recommends better urban sprawl control policies and more property market investment in the ger area to ensure sustainable development goals in Ulaanbaatar.
城市扩张一直在迅速增长，预计到 2030 年将在全球范围内增加两倍。城市化对环境和经济发展有不利影响。居住用地占城市面积的近三分之一，对城市居民有重大影响。蒙古首都乌兰巴托的城市规模显著扩大，特别是在城市周边地区，这些地区的生活条件较差，缺乏基本的城市服务。本文旨在利用模糊逻辑对乌兰巴托市的居住用地进行适宜性分析，基于三个主要类别（适宜居住性、可负担性和可达性）的十五项标准。通过研究，我们确定了一些具有进一步发展潜力的适宜居住区域，例如位于城市南部的公寓式居住区域，以及四个沿主要交通干线分布的低层蒙古包区。此外，结果表明整个城镇的空间结构可能正在向多中心模式转变。然而，“城市周边”的同心环模式显示出对蒙古包区不受控制的扩张，这可能会降低该地区的生活水平。本研究建议采取更好的城市扩张控制政策，并对蒙古包区的房地产市场进行更多投资，以确保乌兰巴托实现可持续发展目标。
