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活动。编制风险预防计划将生成一系列空间数据，并将其归类为多个数据集。 同一份风险预防计划（RPP）可包含以下空间数据集： • 涵盖各类边界的主风险预防计划数据集：包含研究边界、法定管控边界、监管范围； • 计划获批后的限制区域数据集。RPP管控规则通常会区分两类核心区域：其一为“禁止建设区”，即俗称的“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；其二为“需符合特定要求的区域”，即俗称的“蓝色区域”，此类区域风险等级为中等，项目需适配问题类型制定相应管控要求，此外还涵盖未直接暴露于风险但仍受禁令或管制约束的区域； • 致险区域数据集：即标注于风险分析所用危险地图上的区域，需与承险体（stakes）进行空间叠置分析，并明确每个区域所承受的风险等级； • 承险体（stakes）数据集：即受风险威胁、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； • 风险源数据集：即通过自身存在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进行标识。
