Base saturation and sorption assets — INSPIRE Download-Service (WFS-LBGR-BOBASENSORP)

The INSPIRE Download Service enables the download of spatial data for base saturation and sorption capacity in the effective root space in the state of Brandenburg. The content presented was for scale 1: 300,000 created and are larger for representations in scales 1: 100,000 are not suitable. The service is based on the legend units of the soil overview map with corresponding assignment of parameterised surface soil shapes. These represent a soil form society for each legend unit. Base saturation: The individual (area) soil shapes were used with parameters, including the pH and KAC values necessary to derive base saturation, which were determined by ground and laboratory tests. For this purpose, the corresponding parameters (such as pH and KAC values) were statistically derived for the same horizontal-substrate combinations (usually the median value). The sequence of horizontal-substrate combinations in the surface soil forms with their pH and KAC values formed the basis for the calculation of base saturation in the effective root space (see Hennings 2000, link rule 2.4). Sorption capacity: The individual (area) soil shapes were provided with parameters, including the corresponding KAK values determined by terrain and laboratory tests. The same horizontal-substrate combinations were summarised and the corresponding parameters (such as KAK values) were statistically derived (usually the median value). The sequence of horizontal-substrate combinations in the surface soil forms with their KAC values formed the basis for the calculation of the sorption capacity in the effective root space (see Hennings 2000, link rule 2.3).INSPIRE下载服务可用于下载勃兰登堡州有效根际空间内的盐基饱和度（base saturation）与吸附容量相关空间数据。本数据集所呈现的内容按1:300000及更大比例尺制作，不适用于1:100000比例尺的可视化展示。 该服务基于土壤概图的图例单元，并配套赋值了参数化表层土壤形态。各图例单元均对应一类土壤形态组合。 盐基饱和度（base saturation）：本数据集采用各（面域）土壤形态及其配套参数开展计算，其中推导盐基饱和度所需的pH值与KAC参数均通过野外调查与实验室测试获取。针对同一水平-基质组合，通过统计学方法推导得到对应参数（如pH值与KAC值，通常取中位数）。表层土壤形态中各水平-基质组合及其对应的pH值与KAC值序列，为有效根际空间内的盐基饱和度计算提供了依据（详见Hennings 2000，关联规则2.4）。 吸附容量：本数据集为各（面域）土壤形态配套了相关参数，其中推导吸附容量所需的KAK参数通过野外地形调查与实验室测试获取。对同一水平-基质组合进行归总后，通过统计学方法推导得到对应参数（如KAK值，通常取中位数）。表层土壤形态中各水平-基质组合及其对应的KAK值序列，为有效根际空间内的吸附容量计算提供了依据（详见Hennings 2000，关联规则2.3）。
