Water protection areas (WPAs) in Germany: dataset

Groundwater is the most important drinking water resource in Germany. The effects of climate change in combination with diverse physical and social factors affect the quality and quantity of drinking water and pose a challenge for current and future water supply. To safeguard drinking water sources, water protection areas (WPAs) are designated to preserve and protect water from contamination. This spatial dataset consolidates nation-wide information on WPAs. The dataset consists of spatial information on WPA boundaries (a shapefile) and a set of characteristics, including hydrogeological, natural, social, and land cover information in the shapefile’s attribute table. These characteristics were derived from the federal state agencies of Germany and were intersected with the WPA polygons in ArcGIS (version 10.8.1). The dataset may support assessments of groundwater vulnerability and inform sustainable water resource management across Germany.

地下水是德国最为重要的饮用水水源。气候变化与多种自然、社会因素叠加作用，对饮用水的水质与水量造成影响，给当前及未来的供水保障带来挑战。为保障饮用水水源安全，德国划定了饮用水水源保护区（Water Protection Areas，WPAs），以保护水体免受污染。本空间数据集整合了德国全国范围内的饮用水水源保护区相关信息。该数据集包含饮用水水源保护区边界的空间信息（以形状文件（shapefile）格式存储），以及存储于该形状文件属性表中的多维度特征信息，涵盖水文地质、自然环境、社会要素与土地覆被等类别。上述特征信息源自德国各联邦州的相关主管机构，并通过ArcGIS（版本10.8.1）与饮用水水源保护区多边形完成了空间相交处理。本数据集可支撑德国全境的地下水脆弱性评估工作，并为可持续水资源管理提供决策参考。
