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）是政府开展风险防控的核心工具，其核心目标为管控风险区域内的开发建设活动。编制风险预防计划将生成一组空间数据，并被整合为多个数据集。 同一份RPP可包含以下空间数据集： • 涵盖各类边界的主体RPP：包含研究边界、法定规划边界、管控范围； • 计划获批后的限制开发区域：RPP的管控规则通常区分两类区域：一是“禁止建设区”（俗称“红色区域”），此类区域风险等级较高，通用规则为禁止建设；二是“受管控区域”（俗称“蓝色区域”），该类区域风险等级为中等，项目需遵循适配问题类型的管控要求，此外还包括未直接暴露于风险但仍受禁令或规制约束的区域； • 风险分布图中标注的风险区域：该风险分布图通过与承险要素进行空间叠加开展风险分析，并明确每个区域所承受的风险等级； • 承险要素：即受风险威胁、可能因此遭受影响或损失的人员、财产、活动、文化或环境遗产元素； • 风险源：即因自身存在而构成潜在风险的实体对象。该实体可通过名称、外部对象引用或用于定位风险实际来源的地理对象进行标识。
