海南省坡垒种质资源调查报告

Investigation Report on Germplasm Resources of Hopea hainanensis in Hainan Province

通过文献和实地调查相结合的方法对坡垒在海南的分布、植物学性状及其集中分布区域生存状况等进行调查。野生坡垒分布在我省中南部的主要山区,尖峰岭、霸王岭、吊罗山、黎母山、鹦哥岭、五指山、猕猴岭等热带雨林;人工培育坡垒主要分布在海口市、文昌市、五指山市、澄迈县。坡垒优势林主要分布在霸王岭和尖峰岭地区;霸王岭地区有56株60年左右的坡垒树,尖峰岭地区有36株50年左右的坡垒树。海南省坡垒大径材主要分布在昌江县霸王岭、东方市猕猴岭、乐东县尖峰岭、白沙县鹦哥岭。坡垒受到自身生长规律和人为环境影响,导致坡垒生存空间小,存活植株少,种群衰退严重,应积极采取相关措施保护坡垒种质资源。

The distribution of the Hopea hainanensis in Hainan, the botany traits and the living conditions of the concentrated distribution areas were investigated by the combination of literature and field investigation. The wild Hopea hainanensis were distributed in the main mountainous areas in the south-central part of our province, such as Jianfengling, Bawangling, Diaoluoshan, Limushan, Yinggeling, Wuzhishan and Macaoling. The artificial Hopea hainanensis were mainly distributed in Haikou, Wenchang, Wuzhishan, and Chengmai. The Hopea hainanensis-basic forests are mainly distributed in the Bawangling and Jianfengling areas;there are 56 Hopea hainanensis in the Bawangling area, and 36Hopea hainanensis in the Jianfengling area. The large-diameter timber of the Hopea hainanensis in Hainan Province is mainly distributed in Bawangling, Changjiang County, Macao Mountain in Dongfang, Jianfengling in Ledong, and Yinggeling in Baisha. The Hopea hai-nanensis is affected by its own growth law and human environment, resulting in small survival space, few surviving plants, and serious population decline. Active measures should be taken to protect the germplasm resources.
