Landscapes Saxony-Anhalt

The data set includes natural landscapes that are demarcated according to the spread of soils. The basis for this was the overview map of the soils of Saxony-Anhalt 1:200.000. The structure of the soil landscapes follows the cross-border coordinations in Germany, which are carried out in the “Fundkundliche Kartierweisung” (5th edition). Ed. 2005) is executed.
The soil landscapes are hierarchically structured. The structure makes it possible to filter and map different factors complexes of soil development as well as their application in different scales:
1. Soil regions are supraregional areas of equal or similar geological development. They are demarcated after the distribution of quaternary sediments lying on the surface (first point in the number code of soil landscapes).
2. Large soil landscapes are landscape areas with a similar structure of the layer profile in which the soil horizons have formed (second place in the number code of soil landscapes). The large-scale soil landscapes are distinguished according to the nature of the upcoming looser or solid rocks and subdivide the soil regions.
3. Soil landscape groups in some large soil landscapes characterise the distribution area of typical, large-area soil forms (third place in the four-digit number code of soil landscapes).
4. Soil landscapes are local landscape units in which the totality of soil-forming factors acts in the same or similar way (last digit in the number code of soil landscapes). They are further divided into partial landscapes.
The soil regions and large landscapes are coordinated for the Federal Republic of Germany in the Soilkundliche Kartierweisung (2005). According to them, the soil overview maps are in scale 1: 200000 of the Federal Republic of Germany. This structure identifies landscape spaces with similar natural characteristics and subject to the same or similar conditions of protection and use.

本数据集包含依据土壤分布划定的自然景观单元——土壤景观（soil landscapes），其划定基准为萨克森-安哈尔特州1:200000土壤概图。土壤景观的分类体系遵循德国跨区域协调规范，该规范依据《土壤基础制图规范》（2005年第5版）制定。

土壤景观采用层级结构设计，该结构可实现土壤发育各类因子复合体的筛选与制图，并支持多尺度应用：
1. 土壤大区：指具备同等或相似地质演化历程的跨区域单元，依据地表出露的第四纪沉积物（quaternary sediments）分布划定（对应土壤景观编号代码的第一位）。
2. 大型土壤景观：指已形成完整土壤发生层（soil horizons）、土层剖面结构相似的景观单元（对应土壤景观编号代码的第二位）。该类单元依据所出露的松散或固结岩石性质进行区分，并对土壤大区进行细分。
3. 土壤景观群：隶属于部分大型土壤景观，用于表征典型大面积土壤类型的分布范围（对应土壤景观四位编号代码的第三位）。
4. 土壤景观：指土壤形成因子整体作用方式相同或相似的局地景观单元（对应土壤景观编号代码的最后一位），可进一步划分为子景观单元。

土壤大区与大型土壤景观的协调规范由德国联邦层面依据《土壤学制图规范》（2005）制定。据此编制的德国联邦土壤概图比例尺为1:200000。该层级结构可识别具有相似自然特征、适配相同或相似保护与利用条件的景观空间。
