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官方工具，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系列空间数据，并将其划分为多个数据集。 同一份风险预防计划可包含以下类型的空间数据集： • 涵盖各类边界的主风险预防计划：包含研究边界、法定适用边界与监管范围； • 计划获批后的限制管控区域。风险预防计划的监管规则通常会区分两类区域：其一为“禁止建设区”（俗称“红色区域”），此类区域风险等级较高，普遍施行建设禁令；其二为“需满足特定要求的区域”（又称“蓝色区域”），该区域风险等级为中等，开发项目需结合问题类型适配相应管控要求，同时还涵盖未直接暴露于风险但仍需遵守禁令或相关规定的区域； • 风险分析专用风险地图上标注的风险区域：该地图通过叠加承险要素开展风险分析，并明确各区域所承受的风险等级； • 承险对象：即受风险威胁、可能因此遭受影响或损失的人员、财产、活动、文化或自然遗产要素； • 风险源：即实际存在的、其存在本身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。
