摘　　要：【目的】原产地中海地区的双雄雀麦,已成为入侵地的重要农田杂草,给多国农牧业生产带来重大损失。我国口岸已多次从进境动植物及其产品中截获双雄雀麦,应对其入侵风险进行评估。【方法】参照有害生物风险分析程序对其危害性进行评估,应用多指标综合评估方法确定其入侵我国的风险等级。【结果】通过定性和半定量风险分析,得出双雄雀麦在中国的综合风险值(R)为2.12。【结论】双雄雀麦在我国属高风险有害生物,建议口岸检疫部门加强入境农产品的检疫监管和监测调查,及时发现并进行防除。【Aim】Bromus diandrus is indigenous to the Mediterranean region and is an important weed in agricultural ecosystems in many countries.B.diandrus is frequently found in imported agricultural products in Chinese ports.Accordingly,it is necessary to conduct a pest risk analysis.【Method】Following the pest risk assessment protocol,qualitative and quantitative analyses of the invasion risk of B.diandrus were evaluated,a comprehensive risk value(R)wan calculated,and the risk level was determined.【Result】B.diandrus is a strong invader and has rapid colonization abilities,with a R of 2.12.【Conclusion】B.diandrus is considered a high-risk weed.The port quarantine department should strengthen the inspection and field monitoring of B.diandrus in imported agricultural products to ensure timely discovery and eradication.
