ECOSYSTEM FUNCTIONS OF THREE LAKES IN CITY PARK IN MARIBOR

Danes se pogosto pojavljajo vprašanja kako ohraniti naravo in na kakšen način ponovno oživeti in obnoviti ekosisteme, ki so degradirani zaradi različnih pritiskov človeka. Postavlja se seveda tudi vprašanje kaj oziroma katere ekosisteme je vredno ohraniti in kakšen pomen imajo le-ti v naravi in za našo življenje. V diplomskem delu sem raziskala kakšno ekosistemsko vlogo imajo Trije ribniki v mestnem parku v Mariboru. Trije ribniki so stoječe vode in so zaradi majhnih samočistilnih sposobnosti zelo ranljiv ekosistem. Kvaliteta vode v ribnikih je zelo slaba, predvsem zaradi dotoka odpadnih komunalnih voda. Posledično je biodiverziteta majhna. Avtohtone živalske vrste nadomeščajo alohtone živalske vrste, ki se bolje in lažje prilagajajo težjim življenjskim razmeram. V obstoječem stanju ekosistem nudi le skromne ekosistemske funkcije in ekosistemske storitve. Ekosistem Treh ribnikov je potreben obnove, ki je pogoj za večjo živalsko in rastlinsko pestrost. Pri nadaljnji rabi prostora je potrebno upoštevati ekosistemski pristop, ki teži k sanaciji, ohranjanju in sonaravni rabi ekosistema. Trije ribniki imajo potencial, da se uporabijo v vzgojno izobraževalne namene v obliki šolske učne poti. Tako bi mlade generacije bolje razumele, delovanje ekosistemov in pomen ohranitve zdravega ekosistema za boljšo kvaliteto življenja .Today we often ask ourselves, how to preserve our nature and how to revitalize ecosystems witch are degraded because of the human pressures. There is another question, what or witch ecosystems are worth to preserve and what is the meaning of this ecosystems for nature and for our life. In this graduation diploma I researched meaning and part of three lakes in city park in Maribor. Three lakes define as standing waters and therefore are very sensitive ecosystem. Quality of water is of water in lakes is very bad, mainly because of the incoming communal water. The consequence is very small biodiversity. Natural animal species are replaced with species, witch were brought in lakes, and are not so sensitive to the hard life conditions. So has ecosystem of three lakes very small ecosystem meaning and it offers only a few ecosystem services. Ecosystem needs to be reconstructed. Reconstruction is condition for bigger biodiversity. In future use this space is urgent to consider ecosystem approach, witch intention is to reconstruct, preserve and to use ecosystem according to the nature. Three lakes have a potential to be use for an educational intentions. As school water educational way would help younger generations to understand the meaning, functions and importance of preserving a healthy ecosystem, witch is the key meaning for a better quality of life
