This paper addresses the ecological changes and urban unsustainability in metropolises of Iran based on three important indicators: administrative—political centralization, worn-out tissues and urban security. Urban unsustainability engineering is a process in urban planning and urbanization that has not been administrated and managed based on Iranian regional architecture and urban planning. The research data were gathered from a statistical analysis of documents and techniques in a systematic review (1956–2016). The results of the study demonstrated that metropolises of Iran had undergone an unsustainable growth trend. The government seeks to improve indicators of urban sustainable engineering and centralization of the metropolis. Over the past 60 years, cities have been facing rapid growth and development in Iran so that development-oriented governments can play a significant role in tackling growth and urban problems. These problems are especially evident in the socioeconomic and unsustainability of urban ecology. The rapid growth of urbanism and urbanization (74% in 2016) has culminated in the emergence of metropolitan areas in an unstable process. Also in metropolitan areas of Iran, environmental and ecological threats, rural–urban migration and marginalization have posed a serious national-regional challenge. The structural–functional reforms in Iran have been accompanied with skeletal-spatial and socioeconomic changes in cities, giving rise to a new social class called the low-income characterized with non-formal businesses and informal settlements in the outskirts of metropolitan areas.

伊朗大都市的城市不可持续工程

本文基于三个重要指标来论述伊朗大都市的生态变化和城市不可持续性：行政-政治集权、磨损的组织和城市安全。城市不可持续工程是城市规划和城市化的一个过程，没有根据伊朗区域建筑和城市规划进行管理和管理。研究数据来自系统评价（1956-2016）中的文件和技术的统计分析。研究结果表明，伊朗的大都市经历了不可持续的增长趋势。政府寻求改善城市可持续工程和大都市集中度的指标。在过去的 60 年里，伊朗的城市一直面临快速增长和发展，因此以发展为导向的政府可以在解决增长和城市问题方面发挥重要作用。这些问题在城市生态的社会经济和不可持续性方面尤为明显。城市化和城市化的快速增长（2016 年为 74%）最终导致大都市区在不稳定的过程中出现。同样在伊朗的大都市区，环境和生态威胁、城乡移民和边缘化已经构成了严重的国家区域挑战。伊朗的结构-功能改革伴随着城市的骨架空间和社会经济变化，催生了一个新的社会阶层，称为低收入阶层，其特征是大都市区郊区的非正规企业和非正规住区。
