摘 要 ：调查结果表明,铜鼓嶂植物区系种类丰富,共有野生种子植物163科598属1166种,其中裸子植物5科5属6种,被子植物158科593属1160种,含有16种广东省新记录植物。铜鼓嶂种子植物区系地理成分复杂,区系中热带成分占绝对优势,同时也受到温带成分一定程度的影响,铜鼓嶂植物区系与热带植物区系联系强于温带地区。铜鼓嶂特有科仅有大血藤科(Sargentodox aceae)1科,中国特有属8个,在种的水平上特有现象很强,中国特有种515种,占44.9%,其中中国温带-热带亚热带特有种25种,中国热带亚热带特有种490种(包括广东特有种9种,粤东特有种6种)。

Abstract:Tongguzhang mountains is a diverse flora.A total of 1116 native seed plants in 598 genera of 163 families was identified in Tongguzhang Mountains.Among them,There are 6 species in 5 genera of 5 families belong to Gymnospermae,1110 species in 593 genera of 158 families belong to Angiospermae.16 new recorded plants to Guangdong were identified.Tongguzhang flola has complicated geographic elements and predominated by tropic elements.It has close relation to tropic floras and less connection with temperate floras.There are one endemic family(Sargentodoxaceae),8 endemic genera and 515 endemic species to China.As to the endemic species,there are 25 species endemic to Temperate-Subtropic & Tropic China,490 species to the Subtropic & Tropic China( 9 species endemic to Guangdong Province and 6 species endemic to East Guangdong).
