近年来,我国木材输入量逐年增多,主要来自东南亚和北美。根据世界动植物地理区划,东南亚各国与我国长江以南同属东洋区,它们出口的木材多为热带雨林中的阔叶树。我国长江以北属古北区,美国和加拿大属新北区,我国从北美进口的木材几乎全是针叶树。按照动植物区划的原理,从检疫的角度来看,应该特别注意异区或远邻国家的虫种。 In recent years, China’s timber input increased year by year, mainly from Southeast Asia and North America. According to the world zoological flora and fauna, all countries in Southeast Asia and the south of the Yangtze River in China belong to the Toyo region. Most of their exports are broad-leaved trees in tropical rain forests. North of the Yangtze River in China is Gubei District, the United States and Canada belong to the New North District, China imported from North America almost all conifers of timber. According to the principle of zoological division, from the quarantine point of view, special attention should be given to the species of insects in different regions or neighboring countries.
