Expulsion measurement network for eutrophicated areas according to §13a DüV (05/2022)

Measuring points of the surface water bodies for the designation of the eutrophied areas of the state of NRW according to §13a Fertiliser Ordinance. WFD measurement points at surface waters for the designation of the eutrophicated areas of the state of NRW in accordance with §13a Fertiliser Ordinance. The data set contains all measuring points of the WFD measurement network used to identify the eutrophicated areas with regard to phosphate and biology assessment. All identification points have been checked with regard to their suitability for WFD monitoring. Measurement points not suitable for WFD monitoring were isolated and accordingly not taken into account (knowledge level 05/2022). For the update of the eutrophicated areas in December 2022, no changes were made to the expulsion measurement network, which is why, unlike the eutrophicated areas and the field blocks therein, it still remains at 05/2022.本数据集包含依据《肥料条例》第13a条划定北莱茵-威斯特伐利亚州（NRW）富营养化区域所需的、遵循水框架指令（Water Framework Directive，简称WFD）的地表水监测点位。该数据集涵盖WFD监测网络的全部有效点位，用于通过磷浓度与生物学评估识别富营养化区域。所有候选识别点位均已通过WFD监测适用性校验，不符合监测要求的点位已被剔除且未纳入本数据集（数据版本为2022年5月）。2022年12月开展富营养化区域更新工作时，该监测网络未进行任何调整，因此与富营养化区域及其内部地块不同，其数据版本仍维持2022年5月的版本。
