紫茎泽兰在贵州水城县林地的入侵危害和风险评价

Damage and Pest Risk Assessment of Invasive Ageratina adenophora at Forest Land in Shuicheng County

    摘要
  • 摘要: 于2018 年6-9 月对贵州省水城县紫茎泽兰Ageratina adenophora 林地分布范围进行的全面调查，结合林业有害植物风险分析指标体系对紫茎泽兰在水城县林地范围内的潜在危害进行风险分析评价。结果表明，紫茎泽兰在水城县发生面积达7 351.76 hm2，占总调查林地面积的4.07%；紫茎泽兰在水城县的风险综合评价值为2.63，属于特别危险风险等级；紫茎泽兰的分布范围南部地区>东部地区>中部地区>北部地区。灌木覆盖度70%以上的灌木林地和云南松Pinus yunnanensis 林紫茎泽兰不发生或少发生，灌木覆盖度50%以下的灌木林地和杉木Cunninghamia lanceolata 纯林紫茎泽兰最容易入侵，应将预防工作重点放在北部和东部地区，防治的重点范围放在南部与东部地区。

     

    Abstract: Investigations were implemented during June and September of 2018 on distribution of invasive Ageratina adenophora at forest land in Shuicheng county, Guizhou province.Damage and risk of the invasive plant was assessed.The results showed that distribution area of A.adenophora in Shuicheng was 7 351.76 ha, accounting for 4.07% of the total surveyed forest land.The comprehensive risk assessment value was 2.63, meaning special risk.The distribution range of A.adenophora in Shuicheng was South > East > middle > North.Forest land with shrub coverage of more than 70% and Pinus yunnanensis forest had no or distribution of A.adenophora, but that with shrub coverage of less than 50% and pure Cunninghamia lanceolata forest was easy to be invaded.Recommendation was put forwarded to control and prevention in Shuicheng.
