Linz field
The Linzer Feld or Linzer Becken is an area in Upper Austria that lies in the foothills of the Alps from Linz to Enns on the Danube . It is a section of the Upper Austrian Danube Valley, and belongs to the core area of the Upper Austrian central area . With the capital of the city of Linz, it is now very densely populated, but also has good agricultural grounds and extensive aurestas along the Danube.
The almost 100 km² Linz field forms one of 41 Upper Austrian natural spatial units .
geography
Location and boundaries
The Linz field is a largely to Hausruckviertel belonging pool along the middle Danube, at the foot of granite and gneiss highlands ( Mühlviertel ). It encompasses the metropolitan area of Linz as well as the downstream Au and Niederterrassen landscape, over a length of around 20 kilometers and a width of around 3, and in the western part up to 7 kilometers.
The spatial unit of the Upper Austrian natural spatial structure NaLa (No. 17, LF for short) lies in the districts of Linz , Linz-Land , Perg and Urfahr-Umgebung along the Danube. The following municipal areas are mostly in the Linzer Feld (in alphabetical order): Asten , Enns , Linz and Luftenberg .
The area of the spatial unit according to NaLa, which is exactly defined in the geomorphological boundaries of the basin landscape, is 95.23 km². The deepest area is around 245 m above sea level. A. at the mouth of the Enns . The highest point in the area is 290 m above sea level. A. the transition to the north and north-east space units.
The west is marked by the Kürnberger Forest . In the north it is bounded by the Bohemian Massif with Pöstlingberg , Gründberg , Magdalenaberg , Pfenningberg (near Steyregg), Luftenberg and Frankenberg . These massifs (on both sides of the Danube) all belong to the southern Mühlviertel peripheral locations (NaLa 37, SMR) or the Central Mühlviertel highlands (NaLa 41, SMR), the Danube breakthrough at Pöstling, the Linz gate , to the Danube Gorge and side valleys (NaLa 6, DSN) ). To the east of Mauthausen , the Machland (NaLa 18, ML) adjoins the Danube on the left , the lower Ennstal on the right (Lower Austrian spatial unit Enns-Niederung and Unteres Enns and Steyrtal , NaLa 28, UES). In the southeast is the Traun-Enns-Platte ( Traun-Enns-Riedelland , NaLa 37, SMR). In the south-west is the Welser Heide (spatial unit Unteres Trauntal NaLa 36, UT) and north of it foothills of the Inn and Hausruckviertel hills (NaLa 13, IHH).
structure
The Linzer Feld is divided into three scenic - partly non-contiguous - sub-units:
- Dense settlement and industrial area:
-
Lower terrace with agriculture:
- south of the Danube between Linzer and Steyrer boundary, with some cultivation remnants around Traundorf; north of the area between Katzbach and Plesching including Pleschinger See ; at Steyregg and Pulgarn ; in Abwinds , Gusen and Langenstein
-
Danube with floodplain landscape:
- a 2 km wide zone downstream from Linz to Mauthausen: Neuau , Altau and Ringelau near Steyregg; Eastern part of the Traun-Donau-Auen with Weikerlsee (European protected area, only explicit protection zone in the area), Ausee and Lang Au ; Area of power station Abhaben-Asten ; Gusen -Auen with Schlossau ; and Pleschinger Au directly in Linz

With an average temperature of 9 ° C, the Linz Basin is the warmest region in Upper Austria. Around 41% is used for agriculture, 28% is built-up (state capital Linz and the cities of Ansfelden and Steyregg ), 21% forests and near-natural areas and 10% water areas.
- The spatial unit is an extensive, wide gravel plain and is dominated by the Danube .
- The floodplain landscape is partly close to nature and the riparian forests are almost continuous, but isolated from adjacent spatial units. Floods are possible in places, but seldom due to the reservoir for the Wallsee-Mitterkirchen power plant . The riparian forests consist mainly of ash and gray alder forests as well as hybrid poplars . The oxbow lakes are home to aquatic vegetation with rare species. Hot lands are rare and dry meadows with rare plant species exist.
- The large quarry ponds are used for recreation and gravel extraction. The streams from the surrounding area are often regulated, but are being dismantled in a natural way.
- Intensive arable farming is carried out on the agriculturally used low terrace . There are still a few remains of the original cultural landscape ( orchards , single trees, slope meadows ). New settlements and industrial sites are noticeably reducing the agricultural areas.
- The dense settlement area is dominated by the state capital Linz and the 5 km² industrial area ( Voestalpine and Agrolinz Melamine International ). The development is completely loosened up with artificial green spaces (park, cemetery, avenues). Wall joints, roofs and parks serve as urban biotopes.
- The Linz large sewage treatment plant and a large garbage dump near Asten characterize the area.
- The room unit is rich in fog and smog and has low levels of precipitation .
