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, RPP）是政府开展风险防控的核心工具，其核心目标为管控风险易发区域的开发建设活动。编制风险预防计划会生成一系列空间数据，并可划分为多个数据集。 同一份风险预防计划可包含如下空间数据集： • 核心风险预防计划涵盖的边界（含研究范围、管控范围、监管范围）； • 计划获批后的限制开发区域。风险预防计划的监管规则通常将区域划分为三类：一是“禁建区”，即所谓的“红色区域”，此类区域灾害风险等级较高，通用规则为禁止建设；二是“约束管控区”，即俗称的“蓝色区域”，此类区域灾害风险等级为中等，开发项目需适配问题类型落实管控要求；三是未直接受风险影响但仍需遵守禁令或管控要求的区域； • 用于风险分析的灾害风险分布图上标注的灾害风险区域，该分析通过与承灾体叠加完成，并明确标注每个区域所面临的灾害风险等级； • 承灾体：即受灾害威胁、可能遭受影响或损失的人员、资产、活动、文化或环境遗产要素； • 风险源：即现实中因自身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。
