【摘要】 对1984年以来祁连山自然保护区发生分布的7种林业检疫性有害生物进行定性、定量的风险分析与评估,并提出其风险管理及控制策略。结果表明:在祁连山自然保护区圆柏大痣小蜂、杨干透翅蛾为高度危险,落叶松枯梢病、青杨天牛、柳蛎盾蚧、云杉大小蠹为中度危险,泰加大树蜂为低度危险。它们的危险性程度由高到低排序为:圆柏大痣小蜂>杨干透翅蛾>落叶松枯梢病>青杨天牛>柳蛎盾蚧>云杉大小蠹>泰加大树蜂。更多还原

【Abstract】 The paper analyzed and evaluated the seven kinds of domestic forest quarantine pests in Qilian Mountains Nature Reserve since 1984, and the risk management and control strategy were putted forward. According to the results, Megatigmus sabinae and Sphecia siningensis are high risk of forest quarantine pests; Guignardia laricina,Saperda populnea, Lepidosaphes salicina and Dendroctonus micans are medium risk of forest quarantine pests, Urocerus gigas taiganus are low risk of forest quarantine pests in Qilian Mountains Nature Reserve. The order of risk degree from high to low: Megatigmus sabinae>Sphecia siningensis>Guignardia laricina>Saperda populnea>Lepidosaphes salicina>Dendroctonus micans>Urocerus gigas taiganus.更多还原
