摘要: 加拿大一枝黄花Solidagocanadensis L.是我国极具威胁的外来入侵物种之一，主要发生在我国长三角及东南沿海地区.2018—2021年，在黔南独山、贵定、都匀、福泉、长顺、惠水先后发现入侵植物加拿大一枝黄花.本研究运用林业有害生物风险分析指标体系，对加拿大一枝黄花进行定量分析，得出加拿大一枝黄花的风险综合评价值R为2.55.根据林业有害生物风险等级划分标准，判定加拿大一枝黄花在黔南地区属于特别危险类入侵植物.针对黔南地区的发生情况，提出了监测、防治等风险管理措施.Abstract: Solidago canadensis L.is a most threatening invasive alien species in China, mainly occurring in the Yangtze River Delta and southeast coastal areas of China. From 2018 to 2021, the invasion of S. canadensis was discovered successively in Dushan, Guiding, Duyun, Fuquan, Changshun and Huishui of Qiannan Prefecture, Guizhou Province. Based on the collection data of S. canadensis and field investigation, qualitative and quantitative analyses of S. canadensis were carried out using the risk analysis index system of forest pests. The results showed that the comprehensive risk assessment value R of S. canadensis in Qiannan Prefecture was 2.55. According to the classification standards of forest pest risk levels, S. canadensis was identified to be a dangerous invasive plant in Qiannan Prefecture. In response to the occurrence of S. canadensis in Qiannan Prefecture, management measures such as monitoring and prevention are proposed in this paper.
