Abstract
Študij umetnih energijskih vnosov, potrebnih za vzdrževanje ekosistemov, je pomemben pripomoček za razumevanje delovanja krajine. Z analizo umetnih energijskih vnosov (ročno in strojno delo, snovno vnosi) smo prikazali razlike v vrstah in obsegu vlaganj v gospodarskih gozdovih in kmetijskih zemljiščih. S tem srno utemeljili razlike v delovanju gozdnih in kmetijskih ekosistemov in hkrati energijsko podprli »nadzor nad dinamiko v prostoru«, ki je po Formanu (1995) ključni dejavnik za določanje krajinske matice. V kmetijstvu so praktično vsi umetni energijski vnosi potrebni za vzdrževanje sistema, v gozdarstvu pa sodijo mednje energijski vnosi v obliki gojitvenih in varstvenih del. Umetni energijski vnosi, potrebni za vzdrževanje ekosistemov v gozdarstvu, so bili okrog 200-krat nižji od vnosov, potrebnih za vzdrževanje njivskih površin in okrog 100-krat nižji od vnosov za vzdrževanje travinja. Gozdovi obvladujejo dinamiko prostora z mnogo nižjimi energijskimi vlaganji kot kmetijske rabe.

Title:Artificial energy inputs as criteria of landscape matrix maintainance and determination
Abstract:
Study of artificial energy inputs needed to maintain ecosystems is important tool to understand landscape functioning. Analysis of artificial energy inputs (manual and machine work, material inputs) shows the differences in types and amounts of inputs in managed forests and farmlands. In this way the differences in functioning of forest and agricultural ecosystems were founded. Energy based »control over dynamics« in landscape was also established which, according to Forman (1995), is the most important criterion for matrix determination. In farming, practically all the artificial energy inputs are needed to maintain the system. In forestry they represent energy inputs in the form of cultivation and protective measures. Artificial energy inputs needed for maintaining ecosystems in forestry are about a quarter of those needed for maintaining fields and about half those needed in maintaining meadows.

Keywords:forestry, farming, landscape matrix, artificial energy inputs, maintainance of ecosystems
