摘　　要：依据森林生物灾害系统的基本原理,从致灾因子、承灾体和孕灾环境3个方面对东北地区松材线虫Bursaphelenchus xylophilus灾害特征进行分析.结果显示:东北地区松材线虫入侵途径呈多点多条,正在逐步适应当地的主要松树种类和孕灾环境,可通过云杉花墨天牛Monochamus saltuarius完成自然传播.越年枯死现象较为突出,已形成3个较大的发生集群,表现出典型的外来入侵生物的灾害特征,即灾情严重、损失巨大、发展快速、防控难度大,进一步扩散蔓延的潜在风险极大.Based on the basic principle of forest biological disaster system,the disaster characteristics of pine wood nematode in Northeast China were analyzed from three aspects:disaster causing factors,disaster suffering body and disaster inducing environment.The results showed that invasion pathways of pine wood nematode in Northeast China were multipoint and multistrip,and it was gradually adapting to the main pine species and disaster inducing environment locally.The natural transmission of pine wood nematode could be completed by Monochamus saltuarius,which showed a more prominent phenomenon of dying over the years,and three large relatively colonies have been formed.It showed the characteristics of typical invasive biological disasters,namely,serious disaster,huge loss,rapid development,difficult prevention and control.The potential risk of further spread is enormous.
