The Chinese gymnosperm flora is with abundant diversity

ancient origin

and a lot of relict species

and endemic species

which is significant for revealing the construction of local biodiversity and characteristics. In this paper

taking the gymnosperm floras from Taiwan Mountains

Mount Wuyi

Jinggang

Wulingyuan

Emei

Eluo

and Namjagabrwa as the research objects

the authors study the composition of gymnosperm geographical elements

discuss the relationship between the floras and climatic

ecological factors. Following results were obtained: ① In the west China

it is not the floras with abundant gymnosperm species; The east mainland China

the third ladder

has more abundant gymnosperms. ② The geographical elements of genus are relative to local ecological factors

such as elevation

rainfall

quantity of heat. ③ The endemic genera to China are abundant in the east third ladder. ④ In Taiwan

the gymnosperms are with more abundant genera and species; the Abies in Namjagabrwa are more than the other 6 regions. The results from the study are important for indicating the evolution and distribution patterns of gymnosperms.
