摘　　要：参照灾害风险分析方法,通过与华山松大小蠹Dendroctonus armandi、云杉大小蠹D.micans对比分析,从致灾因子的危害性、承灾体的脆弱性和孕灾环境的稳定性3个方面,对东北地区红脂大小蠹D.valens灾害风险进行定性分析。结果表明:红脂大小蠹灾害在东北地区的潜在风险较大,且有向东北腹地进一步扩散危害趋势.Referring to the method of disaster risk analysis,through the comparative analysis with Dendroctonus armandi and D.micans,the disaster risk of D.valens in Northeast China was qualitatively analyzed from harmfulness of disaster causing factors,vulnerability of disaster suffering body and stability of disaster inducing environment.The results showed that the potential risk of D.valens disaster was high in Northeast China,and there was a trend of further spreading to northeast hinterland in China.
