Spatial data set contained in the Flood Risk Prevention Plan file of xxxx

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:

PPR’s main encompassing perimeters (study perimeter, 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;

— hazard areas represented on the map of hazards used for risk analysis by crossing with the stakes, specifying for each zone the level of the hazards to which it is exposed;

issues (persons, assets, 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 entity of the real world 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.

xxxx《防洪风险防控规划》文件所包含的空间数据集。

风险防控规划（Risk Prevention Plans，简称RPP）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。

编制风险防控规划会生成一组空间数据，并划分为若干子数据集。同一份RPP所包含的空间数据集通常涵盖以下内容：

— RPP的核心覆盖范围（研究范围、管控指令范围、合规范围）；

— 规划获批后的管控区域。RPP管控规则通常区分两类核心区域：其一为「建设禁建区」，即俗称的「红色区域」，该区域灾害等级较高，通用规则为禁止建设；其二为「合规管控区」，又称「蓝色区域」，该区域灾害等级为中等，项目需根据问题类型适配相应管控要求，此外还包括未直接受风险影响但仍需遵守禁令或管控要求的区域；

— 灾害分布图上标注的灾害区域，该图层用于风险分析时需与风险点位进行叠加分析，并明确每个区域所面临的灾害等级；

— 受灾害威胁、可能遭受影响或损失的承灾体，包括人员、资产、活动、文化或环境遗产要素；

— 风险源，即现实世界中因其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来表征。
