This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. This is the following: — prescribed scope contained in the prescription order of a PPR (natural); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集收录了PPRN各发展阶段的边界信息。此类边界的特征为：系官方行为的法定产物，且自指定日期起产生法律效力。具体包括以下三类： — 自然类PPR处方令所载的法定适用范围； — 对应获批RPP所规制范围的风险暴露范围，该获批边界属于公共役权（PPRN的PM1）； — 与危险源研究所覆盖范围一致的研究范畴。
