Ekosistemske funkcije stepske krajine ob Bajkalskem jezeru

Julia V. VANTEEVA, Svetlana V. SOLODYANKINA

Povzetek

Na stepe v Priolhonju in gozdne stepe, ki so del nacionalnega parka Pribajkalskij (zahodna obala Bajkalskega jezera, Rusija) imajo pomemben vpliv rekreacijske aktivnosti. Namen raziskave je ocena različnih vrednosti krajine za zagotavljanje ekosistemskih funkcij in uslug. Izvedli smo terenske raziskave v stepi Priolhonje in gozdnih stepah poleti leta 2013. Za različne krajine smo v raziskovanem območju ocenili funkcijo nastanka fitomase in izmerili nadzemno fitomaso in erozijo med jarki. Ocenili smo stopnjo degradacije krajine in naredili karto zaloge fitomase in ranljivosti zaradi erozije tal raziskovanega območja. Da bi prikazali odvisnost med obravnavanimi ekosistemskimi funkcijami in ekosistemskimi uslugami, ki jih le-te zagotavljajo, smo slednje ovrednotili. Ugotovili smo, da se značilnosti ekosistemskih funkcij v stepi v Priolhonju značilno razlikujejo.

Ključne besede

rezanje, ekosistemske usluge, gozdna stepa, zaloga fitomase, simulacija padavin, Rusija, erozija tal.
