摘　　要：加拿大一枝黄花是一种外来入侵检疫性有害杂草,属于多年生草本植物,其根状茎发达,传播速度快,繁殖能力强,通过争夺阳光、水分、土壤养分等资源,对周围的本土植物产生严重的抑制作用,导致其他生物生存空间被大幅挤压,最终死亡,破坏了当地的生态平衡和生物多样性。依据《国际植物检疫措施标准》所规定的有害生物风险性分析程序,对贵阳市及贵安新区加拿大一枝黄花的风险性进行分析后,得出其风险评估R值为2.18,属于高度危险的林业有害生物。从加强检疫及宣传、物理防除、化学防除、生物防除和资源化利用等方面提出了治理措施,以期遏止其扩散蔓延造成的危害。Solidago canadensis Linne,a perennial herbaceous plant,poses significant ecological threats due to its aggressive growth characteristics.The species exhibits extensive rhizome development,rapid propagation rates,and high reproductive capacity,enabling it to outcompete native flora for critical resources including sunlight,water,and soil nutrients.This competitive dominance severely suppresses indigenous plant populations,leading to habitat compression,species displacement,and ultimately local biodiversity loss.According to the Pest Risk Analysis(PRA)procedure specified by the International Standards for Phytosanitary Measures(ISPMs),an analysis of the risk posed by Solidago canadensis Linne in the Guiyang City and Gui'an New Area Prefecture was conducted.the results indicated a risk assessment value(R value)of 2.18,classifying it as a highly hazardous forestry pest.By strengthening quarantine and publicity,physical control,chemical control,biological control,and resource utilization measures,the harm caused by its spread and expansion can be mitigated.
