Abstract:
The research selected Jingyuetan Forest Park in Changchun as research object,floristic composition and floristic elements of spermatophyte in this area were studied by using method of combination of line survey,spot radiation survey and special area investigation,in order to provide scientific basis for the protection and scientific management of wild plant diversity.The results showed that the floristic composition was abundant in this area,there were 503 species,314 genera and 87 families,which contained 9 species,6 genera and 2 families of gymnosperms and 494 species,308 genera and 85 families of angiosperm.It was notable in dominant family,the single-genera and few-genera of angiosperm are rich.The composition of floristic was complex,it contained 15 distribution types and 9 variants types.The temperate elements of genera dominate obviously amounting to 212 genera and making up 81.54% of the genus total in the park.China unique genera was not obvious.Compared with adjacent area,floristic Shannon-Wiener index were obviously different form other 7 area (2.557-2.960),while Simpson′s diversity index were not (0.743-0.811).Shannon-Wiener index of Laotudingzi and Nuluer Hu Mountain were quite high,while Wudalianchi and Changbai Mountain were low.Greater similarity was found among Jingyuetan Forest Park,Changbai Mountain and Zhangguangcai Mountains by cluster analysis.
