Upper pig
The Upper Gau are the main natural unit No. 122 in the south-west German layer level country according to the system of the manual of the natural spatial structure of Germany .
location
They extend between the Black Forest and the Swabian Alb (or the Keuper Mountains) from the origin of the Neckar to beyond the Würmtal . To the north they merge into the Neckar basin and to the south into the Baar plateau .
description
Essentially, two structuring principles determine the landscape: Due to the height development, it is possible to choose between a southern, high-lying (500-730 m), not loess-covered part (Upper Neckargäu) and a northern, lower-lying (400-500 m) and loess-covered part (Upper Gau) can be distinguished. The sequence of geological layers in both parts shows a west-east division from the Heckengäu areas to the Lettenkeuper and Korngäu areas to the Gipskeuper areas. In the Upper Neckargäu, which begins south of a line between Sulz and Horb, the western Heckengäu is predominantly arable. The Lettenkeup part adjoining to the east is mainly characterized by the deeply incised and numerous side valleys of the Neckar valley, which divides the plateau into small-scale units. The heavy clay soils and the steep slopes are mostly forested. The Neckar valley itself is characterized by numerous loops, surrounding mountains, palaces and fortresses and is largely uninhabited. The gypsum keuper zone, equipped with heavy, sensitive soils, connects to the east. The Upper Neckargäu is a historical thoroughfare, which, however, leaves out the deeply cut Neckar valley.
A similar structure can be distinguished in the Upper Gäu, but with different characteristics. The Heckengäu, located to the west, has its greatest spatial expansion, especially along the Nagold and Würmtal valleys. On the karst ridge with barren soils, there are high proportions of forest (pine forests), which are accompanied by sheep pastures in the Würmtal area. The intensity of agricultural use is significantly lower than in the Korngäu to the east. The Korngäu is characterized by a considerable amount of loess. The proportion of forest is low and the predominant agricultural use is intensive. The surface is slightly modeled by rolling hills and dry valleys. The Gipskeupergäu in the eastern area is narrow. Only between Ammer and Schönbuchtrauf is there a wide, predominantly fruit-growing hilly zone in front of the Schönbuch . The north-eastern part of the Upper Gau belongs to the Stuttgart agglomeration and is characterized by dynamic settlement development.
Natural structure
The Upper Gau are structured as follows:
- 122 Upper sheep
- 122.1 Gäuplatten on the upper Neckar
- 122.10 South Eschach Heights
- 122.11 Western Eschach- Heckengäu
- 122.12 Eastern Eschach-Heckengäu
- 122.13 Rottweiler Talk notes
- 122.14 Oberndorfer Gäuplatten
- 122.2 Glatt gauze plates
- 122.20 Glatt-Dorngäu
- 122.21 Gäuplatten above the Glatt
- 122.3 Eyach gauze plates
- 122.4 Upper Gaeu
- 122.1 Gäuplatten on the upper Neckar
Adjacent natural areas in the west are the Black Forest edge plates (No. 150) and the Central Black Forest (No. 153). In the east, the Neckar basin (no. 123), Schönbuch and Glemswald (no. 104), the foothills of the western Swabian Alb (no. 100) and the Baar (no. 121) border.
