| 中文摘要: |
| 外来入侵物种严重威胁着农业生产、生态安全及人类健康,已成为世界各国广泛关注和研究的热点。本文对外来杂草三裂叶豚草(Ambrosia trifida L.)的起源和分布、生物生态学特性、经济和生态影响及其控制管理措施等进行了系统综述。根据生物生态学特性、潜在风险及管理控制的难度等指标,初步建立了外来杂草的风险评估体系。应用该体系对三裂叶豚草进行了风险评估,得出其风险值为83,属高度危险的检疫性有害生物。 |
| 英文摘要: |
| Invasive alien species posed a great threat to agricultural production,ecological safety and human health,which drew much public attention and became the hotspot of research all over the world.The origin,distribution,bio-ecological characteristics,economic and ecological impacts and relevant management strategies of giant ragweed(Ambrosia trifida L.),an exotic weed,were reviewed in this paper.Based on the bioecological characteristics,potential risks,difficulties in prevention and other factors,a risk assessment system on exotic weeds was established.According to this system,the risk value for giant ragweed was 83 and it was considered as a quarantine pest with high risk. |
