摘要：Invasive species endanger the thriving of autochthonous vegetation and can also pose a serious threat to the health of humans,which makes their presence in sporting and recreational fields,which are supposed to be the parts of conserved and “healthy” area,even more so unwanted and intolerable.The presence of invasive and potentially invasive plant species in most frequently visited sporting and recreational fields in Belgrade,such as the area of Ada Ciganlija,Bojčinska šuma and leisure field “Zabran”,has been analysed in this paper.At the area of research,the presence of 19 invasive and potentially invasive species was stated.The analysis ofthe represented specie families has shown the presence of 11 families,the most represented of which beeing the Asteraceae family (8 species),whereas the second most represented was Rosaceae family (2 species).At the sporting and recreationalarea of Ada Ciganlija,the total number of species stated was 96,out of which 18 species (17,82%) being invasive and potentially invasive.In addition to this,the greatest number of invasive species was determinedwithin this Sporting and recreational area.The species of Aster lanceolatus,Urtica dioica and Stenactis annua,as well as Erigeron canadensis were distinguished by its degree of representation.At the sporting and recreational area of “Zabran”,the total number of species determined was 53,out of which 10 species (18,52%) being stated as invasive and potentially invasive.The species of Urtica dioica and Aster lanceolatus were distinguished by its greatest number andhighest level of distribution.At the sporting and recreationalarea ofBojčinska šuma,the total number of recorded species was 63,out of which 11 species (17,46%) being stated as invasive and potentially invasive.The species of Aster lanceolatus and Stenactis annua were distinguished by its greatest number andhighest level of distribution,whereas the specie of Xanthium strumarium var italicum was distinguished by its lowest number and distribution.
其他摘要：Invazivne vrste ugrožavaju opstanak autohtone vegetacije a mogu i ozbiljno da ugrožavaju ljudsko zdravlje pa je njihovo prisustvo na sportsko-rekreativnim površinama koje treba da predstavljaju mesta očuvanog i „zdravog” predela,dodatno nepoželjno i nedopustivo.U radu je analizirano prisustvo invazivnih i potencijalno invazivnih biljnih vrsta na najposećenijim sportsko-rekreativnim površinama u Beogradu: Ada Ciganlija,Bojčinska šuma i izletište „Zabran”.Na istraživanim površinama konstatovano je prisustvo 19 invazivnih i potencijalno invazivnih vrsta.Analiza zastupljenih familija pokazuje prisustvo 11 familija,među kojima je najzastupljenija familija Asteraceae (8 vrsta),dok se na drugom mestu nalazi familija Rosaceae (2 vrste).Na sportsko-rekreativnoj površini Ada Ciganlija konstatovan je ukupan broj vrsta koji iznosi 96,a od tog broja 18 vrsta (17,82%) je invazivan i potencijalno invazivan.Ujedno,na teritorije ove sportsko-rekreativne površine je utvrđen i najveći broj invazivnih vrsta.Svojom zastupljenošću ističu se vrste Aster lanceolatus,Urtica dioica i Stenactis annua,kao i vrsta Erigeron canadensis.Na sportsko-rekreativnoj površini „Zabran” utvrđen je ukupan broj vrsta i iznosi 53.Od tog broja konstatovano je 10 (18,52%) invazivnih i potencijalno invazivnih vrsta.Najvećom pokrovnošću i brojnošću ističu se vrste Urtica dioica i Aster lanceolatus.Na sportsko-rekreativnoj površini Bojčinska šuma ukupan broj evidentiranih vrsta iznosi 63,od koga je konstatovano da su 11 (17,46%) invazivne i potencijalno invazivne vrste.Najvećom brojnošću i pokrovnošću ističe se vrsta Aster lanceolatus,kao i vrsta Stenactis annua,dok se najmanjom brojnošću i pokrovnošću karakteriše vrsta Xanthium strumarium var italicum.
