随着世界人口的迅速增加和工业的日益发展,能源越来越紧张,成为当前许多国家密切关注的问题。近年来,巴西发现了“石油树”——苦配巴(Copaiba)。引起我们对油楠这一珍贵树种的重视。油楠(Sindora glabra Merr.ex De Wit.)属于苏木科的油楠属。本属约有10种,分布在亚洲热带地区。据记载我国仅有这一种,天然生长于海南岛尖峰岭、吊罗山、坝王岭林区,崖县、白沙、乐东、占县、屯昌等县境内也曾发现。由于岛上森林日遭破坏,油楠的分布范围大为缩小,资源日益减少。目前,除了三大林区尚存数量不多的大树,其他各县均极稀少,甚至绝灭。
With the rapid increase of the world’s population and the continuous development of industry, energy has become increasingly tense and has become a matter that many countries now pay close attention to. In recent years, Brazil has discovered the “oil tree” Copaiba. Caused us the importance of this precious species of oil Nan. Saponaria (Sindora glabra Merr.ex De Wit.) Belong to the genus Hematoxylin. The genus is about 10 species, located in tropical Asia. According to records, there is only one such species in our country that was naturally found in Jianfengling of Hainan Island, Diaoluoshan, Damwangling, Cliff, Baisha, Ledong, Zhanxian, Tunchang and other counties. Due to the destruction of the forest on the island, the distribution range of oil nan was greatly reduced and the resources decreased day by day. At present, except for the small number of trees that still exist in the three major forest areas, the other counties are extremely rare and even extinct.
