Soil Assessment — Soil Clinical Moisture Level (BKF)

The soil-based moisture level is a characteristic value for the assessment of the habitat for natural plants (associations) and is evaluated by soil water balances. These are mainly controlled by water retention capacity, groundwater connection, precipitation and evapotranspiration. Sites with very low (dry) or very high (wet) soil-based moisture levels can usually only be used for agriculture with high effort and are therefore often of particular interest as extreme sites for nature conservation. With the soil-based moisture level, a natural soil function is assessed in accordance with § 2(2) of the BBodSchG, namely in accordance with point 1.a) the livelihood and habitat for humans, animals, plants and soil organisms. The criterion chosen for this purpose is the location potential for natural plant societies with the characteristic value of soil-based moisture level. The maps are available for the following scale levels: — 1: 1,000-10 000 for high-resolution or parcel-sharp planning, — 1: 10,001-35,000 for municipal planning, — 1: 35.001-100,000 for planning in larger regions, — 1: 100.001-350,000 for nationally differentiated planning, — 1: 350,001-1000,000 for nationwide to nationwide planning.土壤基含水率（soil-based moisture level）是评估天然植物群落（associations）生境的特征指标，其评估依托土壤水平衡完成。土壤水平衡主要受持水能力、地下水连通性、降水量与蒸散发的共同调控。 土壤基含水率极低（干旱）或极高（湿润）的地块，通常仅能通过高投入开展农业生产，因此这类极端生境往往成为自然保护领域的重点关注对象。 依据德国《联邦土壤保护法（BBodSchG）》第2条第2款，土壤基含水率可用于评估自然土壤功能，即契合该法规第1.a项中关于人类、动物、植物及土壤生物的生存与栖息环境的要求。 本次评估选用的判定标准为：以土壤基含水率为特征值的天然植物群落立地潜力。 该数据集配套的地图适用于以下比例尺等级： — 1:1000~10000：用于高分辨率或地块级精准规划； — 1:10001~35000：用于市政规划； — 1:35001~100000：用于较大区域规划； — 1:100001~350000：用于全国差异化规划； — 1:350001~1000000：用于全国范围至全国范围的规划。
