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 (prescription perimeter, regulated perimeter); • 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; • 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. The data are informative, only paper documents with the prefecture’s visa are authentic.风险预防计划（Risk Prevention Plans，RPPs）是政府开展风险防控的核心工具，其目标为管控风险区域内的开发活动。 风险预防计划的编制会生成一系列空间数据，并被划分为多个数据集。同一RPP可包含如下空间数据集： • 涵盖各类范围的主体RPP数据（含规定边界、管控边界）； • 计划获批后的受限区域数据； • 风险源数据：即通过其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风险实际来源的地理对象来表征。 RPP的监管条例通常会对相关区域进行分类界定：一类为“禁建区域”，即所谓“红色区域”，此类区域危险等级偏高，通用规则为禁止建设；另一类为“受管控区域”，又称“蓝色区域”，此类区域危险等级为中等，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管控要求约束的区域。 上述数据仅为参考信息，唯有加盖行政当局签章的纸质文件方为有效。
