| 中文摘要: |
| 对南涧县古树名木资源现状进行调查,分析其空间分布格局、优势树种及生长状况等。结果表明,南涧县483 株古树分布于5镇3乡,分属20科31属51种。南涧县古树优势树种主要是黄
葛树;树高为10~19.9 m的古树231 株,占比47.83%;胸径为300~399 cm的古树126 株,占比
26.08%。树高、胸径、冠幅三者间存在正相关关系。以期为南涧县古树资源的保护管理、抢救复壮、林木种质资源保护和研究提供理论基础。 |
| 英文摘要: |
| Based on the investigation of the present situation of ancient and famous tree resources in Nanjian
County, this study analyzed their spatial distribution pattern, dominant tree species, and growth status.
The results indicated that a total of 483 ancient and famous trees distributed in 5 towns and 3 townships,
belonging to 51 species, 31 genera and 20 families. The dominant tree species in Nanjian County
was Ficus virens. Among the recorded trees, 231 ancient trees(47.83%) had a height ranging from 10
to 19.9 meters, and 126 trees(26.08%) had a diameter at breast height (DBH) between 300 and 399
centimeter. Positive correlations were observed among tree height, DBH and crown width. This study
aims to provide a theoretical basis for the protection management, rescue and rejuvenation, and conservation
and research of germplasm resources of ancient trees in Nanjian County. |
