This paper aims at proposing a possible alternative point of view to investigate the vulnerability of urban systems. The basic ideal refers to the possibility of thinking about vulnerability as deriving by the interactions of several risks that can affect the urban system and by the interactions among them. In this sense, it is possible to refer to an “integrated territorial risk”. Considering the city as a complex and dynamic system that while evolving produce entropy is the main theoretical reference supporting this study. The loss of energy during the evolution of the system corresponds to some conditions of inefficiency that involve the whole system and, as such, this lost energy can be assumed as a “systemic entropy”. Is it possible to measure the levels of this vulnerability of the urban system when it stays in ordinary conditions, namely not during stress states that modify the state of equilibrium of the system itself? It is possible to assess the production of this “internal entropy”? In order to answer to these questions in mind, this study aims at analyzing dyscrasias that can occur within the main components of the urban system in order to individuate possible strategies able both to mitigate the fragility of the urban system and to improve its resilience.

重新思考城市系统的脆弱性:评估“城市熵”的方法建议



本文旨在提出一种可能的替代观点来研究城市系统的脆弱性。基本理想是指将脆弱性视为由可能影响城市系统的多种风险的相互作用以及它们之间的相互作用产生的可能性。从这个意义上来说,可以称为“综合领土风险”。将城市视为一个复杂的动态系统,在演化过程中产生熵是支持本研究的主要理论参考。系统演化过程中的能量损失对应于涉及整个系统的某些低效率条件,因此,这种损失的能量可以被假设为“系统熵”。当城市系统处于正常条件下时,即不是在改变系统本身平衡状态的压力状态下,是否有可能测量城市系统的脆弱性水平?可以评估这种“内熵”的产生吗?为了回答这些问题,本研究旨在分析城市系统主要组成部分中可能发生的恶习,以便制定可能的策略,既能减轻城市系统的脆弱性,又能提高其复原力。
