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，其核心目标是对风险区域内的开发活动进行管控。编制风险预防计划会生成一系列空间数据，并归类为多个数据集。 同一风险预防计划（RPP）所包含的空间数据集通常涵盖以下内容： • 核心风险预防计划的各类边界（研究边界、规定边界、管控范围）； • 计划获批后的管控区域。风险预防计划的管控规则通常会区分两类核心区域：其一为‘禁止建设区’，即所谓的‘红色区域’，此类区域危险等级较高，通用规则为禁止建设；其二为‘合规要求管控区’，亦称‘蓝色区域’，该类区域危险等级为中等，区内项目需遵循适配问题类型的管控要求，此外还包括未直接受危险影响但仍需遵守禁令或规定的区域； • 用于结合承险对象叠加开展风险分析的隐患分布图上标注的隐患区域，需明确每个区域所面临的危险等级； • 承险对象（stakes）：即受危险威胁、可能遭受影响或损失的人员、财产、活动、文化或环境遗产要素； • 风险源：即因自身存在而构成潜在风险的现实实体。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来标识。
