摘要
为掌握加拿大一枝黄花Solidago canadensis L.在贵州省黔东南地区的发生情况和风险等级,并提出防控策略,防止其进一步快速传播扩散.2022 年1 月至11 月通过走访调查,分析和研究加拿大一枝黄花在贵州省黔东南地区的入侵及分布情况,运用林业有害生物风险分析指标体系开展了定量分析评估.结果表明,加拿大一枝黄花于2015 年首次入侵黔东南,7 年间扩散到境内14 个县41 个乡镇,其风险综合评价值R为2.58.加拿大一枝黄花在黔东南地区呈多点分布,处于定殖阶段,部分点分布面积大,属于特别危险风险等级.针对加拿大一枝黄花在黔东南地区的发生分布情况,本研究提出了监测、防治等风险管理措施.
Abstract
In order to understand the occurrence and risk level of Solidago canadensis L.in the Qiandongnan Prefecture,Guizhou Province,and proposed prevention and control strategies of S.canadensis to prevent further rapid spread,the investigation was carried out to analyze and study the invasion and distribution of S.canadensis in Qiandongnan Prefecture from January to November 2022,and the forestry pest risk analysis index system was used to conduct quantitative analysis and evaluation.The results indicated that S.canadensis invaded Qiandongnan Prefecture for the first time in 2015 and spread to 41 townships in 14 counties during 7 years,and the comprehensive evaluation R-value was 2.58.S.canadensis was distributed in multiple locations in the Qiandongnan Prefecture,which was in the stage of colonization.Some spots had a large distribution area and belonged to a particularly dangerous risk level.According to the distribution of occurrence of S.canadensis in the Qiandongnan Prefecture,this study proposed the risk management measures such as monitoring,prevention and control.
