Risk prevention plans (RPPs) are the State’s key instrument for risk prevention. Their objective is to control development in areas at risk. The development of a PPR generates a spatial dataset organised into several data sets. The same PPR includes the spatial datasets containing: — scope of exposure to risks, — restricted areas of the plan once approved. The RPP regulations distinguish between ‘Building prohibited areas’, known as ‘red areas’, where the general rule is the prohibition on construction; ‘required areas’, known as ‘blue zones’ where projects are subject to requirements adapted to the type of issue and hazard, and areas not directly exposed to risks but subject to prohibitions or requirements. The data are informative, only paper documents with the prefecture’s visa are authentic.风险预防计划（Risk Prevention Plans，简称RPPs）是国家实施风险预防工作的核心手段，其核心目标为管控风险区域内的开发活动。 一项风险预防计划的编制会生成一套空间数据集，该数据集可划分为若干子数据集。该风险预防计划所包含的空间数据集涵盖以下内容： — 风险暴露范围； — 计划获批后的限制区域。风险预防计划相关法规将此类限制区划分为三类：一是‘建筑禁止区’，又称‘红色区域’，通用规则为禁止开展建筑活动；二是‘合规要求区’，又称‘蓝色区域’，区内项目需根据具体问题类型与灾害类型适配相应管理要求；三是未直接暴露于风险之下，但仍需遵守相关禁止性规定或合规要求的区域。 本数据集仅作参考信息，唯有加盖县级行政区域核准签章的纸质文件方为有效凭证。
