The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor development in areas exposed to a major risk.The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through construction prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on use or agricultural practices, etc.).These plans may be under development (prescribed), implemented in advance or approved.The PPR file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPR is identified by a polygon that corresponds to the set of affected municipalities within the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state. This geographical table allows to map existing PPRNs on the department.风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日颁布的《关于加强环境保护的法案》确立，是国家在风险预防领域的核心管控工具。其目标为对面临重大风险的区域的开发活动开展动态监测。PPR由法国省长批准，通常由领土事务总局（DDT）负责具体落地实施。此类计划通过对新建或既有建筑设定建设禁令或相关要求（包括建设管控条款、减灾工程、使用限制或农业生产规范等），对土地利用行为进行规范。PPR可分为三种状态：待编制（已下达编制指令）、预实施及已批准。PPR文件包含说明文档、监管区划图及配套规定，亦可附加其他有助于理解该计划的图文资料（如灾害分布、敏感问题相关资料等）。每份PPR由一个多边形进行标识：当处于待编制阶段时，该多边形对应编制指令覆盖范围内的所有受影响市镇；当处于已批准阶段时，则对应受限区域的范围包络线。本地理数据表可实现部门级已存PPR的空间制图展示。
