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.本数据集涵盖PPRN在各发展阶段的边界范围。此类边界的核心特征为：系官方行为的产物，且自指定日期起生效。具体包括以下三类： — 自然PPR处方令所载明的规定范围； — 对应经核准RPP所规制范围的风险暴露范围；该经核准的边界属于公用役权范畴（适用于PPRN的PM1类型）； — 对应危险源研究覆盖包络的研究范围。
