Ljubljana Basin
The Ljubljana Basin ( Slovenian Ljubljanska kotlina , as a natural space Kotline Dno Ljubljanske ) is an edge alpine basin between the Steiner Alps (Kamniško-Savinjske Alps) and the Karst Slovenia ( Dinarski kras Slovenije ) . It extends in an X-shape over about 30 × 20 km (around 400 km²) and forms the urban area of Ljubljana and the living space for 420,000 people. In terms of traffic, it is the junction between the Southern Alps, Carniola and the Adriatic Sea.
The center of the Ljubljana Basin flows through the Sava from the northwest and its tributary Ljubljanica from the southwest . Between the Ljubljanski vrh and the Ulovka (801 m) the shortest and flattest transition from the basin opens up over the wooded karst heights of Innerkrain to the Adriatic coast .
Geography and biology
The wooded low mountain range Polhograjsko hribovje (750 to 1200 m, see also Gorenjska ) as well as Rakitna, Bloke, Suha Krajina, Hribovje and Posavsko rise around the Ljubljana basin . The capital separates the fertile lowlands in the north (the Ljubljana Polje ) and the slightly deeper marshes in the south ( Ljubljana Marshes , the Ljubljana moor). Although the latter is of no agricultural importance, it is characterized by high biodiversity and is therefore a Natura 2000 area. Birds are here u. a. Black stork and reed warbler native, furthermore king corn , hen harrier and red-footed falcon.
During the day in the Ljubljana Basin there is a penetration of a wind current that comes mainly from the east and south-east; in the sense of a mesoscale circulation system that develops between the Alps and the foreland.
Comparable geographical units of this area are the Save Plain , the Savinja Plain (Sann Plain) and the Cilli Basin ( Celjska kotlina ).
