摘　　要：长林小蠹是原产欧洲的一种重要的森林害虫,可随木质包装材料、衬垫及原木运输而传播扩散,已经成功入侵到世界多个国家和地区。随着我国进口木材量的增加,我国口岸截获外来长林小蠹的频率增高,因此,长林小蠹入侵我国的风险正逐步提高。本文以长林小蠹在全球的分布数据为基础,利用Max Ent模型和Arc-GIS对长林小蠹在我国的适生区进行了分析预测,结果表明:该害虫中高度适生区主要分布在我国云南、贵州、广西、湖北、陕西、甘肃、台湾、安徽、浙江、福建、江西、湖南等省份。因此各口岸需要加强对长林小蠹的检疫,以防止该害虫的传入和定殖。Hylurgus ligniperda（Fabricius）,a highly invasive forest pest,is native to Europe and can be carried by solid wood packing material,dunnage or logs. It has successfully invaded many countries and regions around the world. With the increasing of imported timber,Hylurgus ligniperda has been intercepted many times at China port,which means that the risk of this pest invading our country is increasing.Its potential geographical distribution in China was analyzed by using Max Ent model and Arc-GIS with the occurrence records all over the world. The results show that Yunnan,Guizhou,Guangxi,Hubei,Shaanxi,Gansu,Taiwan,Anhui,Zhejiang,Fujian,Jiangxi,Hunan provinces are the medium and high suitable areas for the live of Hylurgus ligniperda,so that the quarantine measures should be strengthened at ports in order to prevent its introduction and establishment.
