当今世界用材林的造林树种很多。针叶树以松、杉、柏三科中的一些树种为主,阔叶树则多种多样。我国南方造林树种向来有松杉栎竹四大类的说法。竹子有其特殊性,严格说来不能算作阔叶树之列。栎类因其幼年生长较慢,近若干年来已很少用于造林,其地位已为杨树和桉树所替代,有北杨南桉之说,和世界潮流相一致。 In today’s world there are many tree species afforesting. Conifers to pine, fir, cypress three branches of the main species, broad-leaved trees are varied. The afforestation species in southern China have always had four types of coniferous fir oak. Bamboo has its particularity, strictly speaking, can not be counted as broadleaf tree. Quercus, due to its slow growth in early years, has rarely been used for afforestation in recent years. Its status has been replaced by that of poplar and eucalyptus, which is in accordance with the trend of the world.
