It was found that is Songshan Mountain,there were 393 species of woody plants belonged to 152 genera and 60 families. Based on their geographical distribution pattern,the 152 genera were classified into 13 types,among which temperate and tropical plants accounted for 67.57% and 28.38%,respectively. Moreover,the floristic elements pattern showed that the temperate floristic elements were predominant in Songshan Mountain,according to the characteristics of genera and species. It had an extensive linkage to the temperate and tropic zone of each continent at the level of genera,while it had a close relation to the East Asia-Japan zone at the level of species. Furthermore,it also had high correlation with the North China flora zone at the level of endemic species. In the whole,the woody plants zone in Songshan Mountain was originated old age and contained 13 monotypic,8 rare and endangered species. Therefore,it is necessary to protect the woody plants in Songshan Mountain.展开更多
