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.本数据集涵盖了PPRN开发各阶段的边界范围。此类边界范围的核心特征为：系官方行为所产生的法定结果，且自指定日期起生效。具体包括以下三类：—— 天然PPR指令文书中载明的规定范围；—— 经核准的RPP所规制的风险暴露范围，该经核准的边界范围属于公共役权范畴（PPRN对应的PM1）；—— 用于开展危害研究的研究覆盖范围。
