Urban expansion is a phenomenon that has been observed since the mid-20th century in more developed regions. One aspect of it is the urban development of holiday resorts with second homes that generally appeared following world political stabilisation. This residential expansion has often happened with scarce control, especially in its early stages, allowing areas to be occupied that are not so suitable in terms of the environment, culture and landscape, not to mention the very geological risks of flooding, earthquakes and landslides. Indeed, the risk of landslides for buildings occupying land in zones at such risk is not a matter solely attributable to the geomorphological characteristics of the land itself, nor is it simply a question of chance; it is also due to its management of such land, generally because of a lack of specific regulations. This study aims to lay down objective criteria to find how suitable a specific local entity's risk management is by looking at the evolution of its urban development procedures. It also aims to determine what causes the incidence of landslide risk (geomorphology, chance, land management, etc.) and finally to suggest control tools for the public bodies tasked with monitoring such matters.

扩展住宅区的滑坡风险管理分析——La Marina 案例研究（西班牙阿利坎特）

城市扩张是一种自 20 世纪中叶以来在较发达地区观察到的现象。一方面是在世界政治稳定后普遍出现的带有第二居所的度假胜地的城市发展。这种住宅扩张经常在缺乏控制的情况下发生，尤其是在其早期阶段，允许占用环境、文化和景观方面不太合适的区域，更不用说洪水、地震和山体滑坡等地质风险。事实上，在这种风险地区占用土地的建筑物发生山体滑坡的风险不仅仅取决于土地本身的地貌特征，也不仅仅是一个偶然的问题；这也是由于它对这些土地的管理，一般是因为缺乏具体的规定。本研究旨在制定客观标准，通过考察特定地方实体的城市发展程序的演变来确定其风险管理的适用性。它还旨在确定导致滑坡风险发生的原因（地貌、机会、土地管理等），并最终为负责监测此类事件的公共机构建议控制工具。
