| Abstract: | Jinggangshan Mountain National Nature Reserve lies in southern Jiangxi Province. A floristic system of woody plants was studied in Jinggangshan Mountain National Nature Reserve.There were 991 species of woody plants belonging to 305 genera and 95 families in the investigation,of which the gymnosperm was 15 species,13 genera and 8 families,and the angiosperm was 976 species,292 genera and 87 families.The few-species families,few-species genera and single-species genera took larger proportion in the composition of the families and genera.The floristic analysis showed the geographical element was complex,the tropical element dominated the whole woody plants,and temperate element took larger proportion.The flora origin was ancient,and the flora remained many floristic elements before the Quaternary.There were many national important protected plants and endemic plants. |
