Risk Prevention Plans (RPPs) are the key government instrument for risk prevention. Their objective is to control development in areas at risk. The development of a risk prevention plan generates a set of spatial data organised into several data sets. The same PPR may include spatial datasets containing: • main PPR encompassing perimeters (study perimeter, prescription perimeter, regulated scope); • restricted areas of the plan once approved. RPP regulations generally distinguish between ‘construction ban areas’, so-called ‘red areas’, where the hazard level is high and where the general rule is the construction ban; ‘areas subject to requirements’, known as ‘blue zones’ where the hazard level is medium and projects are subject to requirements adapted to the type of issue and areas not directly exposed to risks but subject to prohibitions or prescriptions; • hazard areas represented on the map of hazards used for risk analysis by crossing with the stakes, specifying for each zone the level of hazards to which it is exposed; • stakes (persons, property, activities, cultural or environmental heritage elements) threatened by a hazard and likely to be affected or damaged by it; • origins of risk, i.e. the real-world entity which, through its presence, represents a potential risk. This entity may be characterised by a name, a reference to an external object or a geographical object that locates the actual entity causing the risk.风险预防计划（Risk Prevention Plans, RPPs）是政府开展风险预防工作的核心工具，其目标为管控风险区域内的开发活动。制定风险预防计划会生成一组空间数据，并将其划分为多个数据集。 单个风险预防计划所包含的空间数据集通常涵盖以下内容： • 涵盖各类边界的核心风险预防计划（研究边界、规定边界、管控范围）； • 计划获批后的限制开发区域。风险预防计划的管控规则通常区分两类核心区域：一是"禁止建设区"（即所谓"红色区域"），此类区域风险等级较高，通用管控规则为禁止建设；二是"受约束建设区"（亦称"蓝色区域"），此类区域风险等级为中等，建设项目需根据问题类型适配相应管控要求，此外还包括未直接暴露于风险之中但仍需遵守禁令或相关规定的区域； • 风险分布图上标注的风险源区域，该分布图通过与承灾体叠加开展风险分析，并明确标注每个区域所面临的风险等级； • 承灾体：即受风险威胁、可能遭受影响或损失的对象，涵盖人员、资产、各类活动、文化或自然遗产要素； • 风险源：即现实中因其存在而构成潜在风险的实体。该实体可通过名称、外部对象引用或用于定位实际致险实体的地理对象进行标识。
