摘　　要：按照PRA准则,结合杂草检疫工作的实际,建立了口岸外来杂草截获危险性定量判定的一、二级评判的模型;选取了8种不同科属的杂草对其危险性进行了定量分析,结果表明:8种杂草分成特别危险、高度危险、中度危险3个等级,其中法国野燕麦(Avena ludoviciana Durien)处于特别危险,苍耳属(非中国种)[Xanthium spp.(non-Chinese species)]、豚草(Ambrosia artemisiifolia L.)、假高粱(Sorghum halepense)、长芒苋(Amaranthus palmeri)、粗刺曼陀罗(Datura ferox)、处于高度风险,美国合萌(Aeschjnomene americana L.)与南方牵牛(Ipomoea cordatotriloba Dennst.var.australis)处于中风险。According to the rule of pest risk analysis （ PRA） and the actual of weed quarantine,the risk of eight different families and genera weeds were selected to do quantitative analysis by establishing the calculation model of judging the first grade and the second grade criterion estimation.Weeds could be grouped in tree levels：particular,high and moderate risk.Avena ludoviciana Durien belonged to particular risk,Xanthium spp.（non-Chinese species）,Ambrosia artemisiifo-lia L.,Sorghum halepense,Amaranthus palmeri and Datura ferox belonged to high risk,and Aeschjnomene americana L. and Ipomoea cordatotriloba Dennst.var.australis belonged to moderate risk.
