For natural PPRs, the environmental code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures may be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. Regulations generally distinguish three types of zones: 1- ‘building prohibition zones’, known as ‘red zones’, where the hazard level is high and the general rule is the prohibition on building; 2- ‘zones subject to requirements’, known as ‘blue zones’, where the hazard level is average and projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, structures, development or agricultural, forestry, artisanal, commercial or industrial operations could aggravate or cause new risks, subject to prohibitions or requirements (see Article L562-1 of the Environmental Code). The latter category applies only to natural PPRs.针对自然风险预防规划（natural PPRs），《环境法典》（Environmental Code）第L562-1条将区域划分为两类：风险暴露区，以及未直接面临风险但需采取措施以避免风险加剧的区域。 根据危险等级的不同，每类区域均需遵循可强制执行的管控要求。相关法规通常将区域划分为三类： 1. 禁止建设区（“红区”）：危险等级较高，通用规则为禁止开展建设活动； 2. 受管控要求约束区（“蓝区”）：危险等级为中等，建设项目需遵循适配问题类型的管控要求； 3. 未直接面临风险，但建设、构筑物搭建、开发活动或农业、林业、手工业、商业及工业作业可能加剧风险或引发新风险的区域，需遵循禁止性规定或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于自然风险预防规划场景。
