摘要: 为了解薇甘菊在德宏州入侵的危险性,对不同生境薇甘菊发生情况进行实地调查监测,建立风险分析评价体系,采用多指标综合评分法,对其入侵风险进行评估。结果表明,薇甘菊发生具有区域性分布特征,立体分布明显,主要分布于中低海拔热区,发生面积31991.87hm2,入侵风险评估R值达68,具有极高的生态风险,目前,尚有304985.4hm2潜在发生区处于薇甘菊的威胁中。薇甘菊入侵农田、荒地、林地,不仅给农业、林业造成了不同程度的经济损失,对生态环境也产生严重威胁,必须采取有效措施及时防控。

Abstract: In order to understand the risk of Mikania micrantha invasion in Dehong, the occurrence of Mikania micrantha was investigated and monitored in different habitats, and the system of risk analysis and assessment was established. Multi-index comprehensive scoring method was used to assess the invasion risk. The result showed that Mikania micrantha had regional distribution characteristics with three- dimensional distribution obviously and mainly distributed in low altitude tropic region, the occurrence area was nearly 31991.87 hm2, with invasion risk assessment value R of 68, Mikania micrantha had high ecological risk. At the moment, 304985.4 hm2 of potential occurrence area is still under threat of Mikania micrantha. Mikania micrantha mainly invades farmland, barren land and forest land, it not only causes great loss in agriculture, forestry and husbandry, but also threats eco-environment, we must take effective measures to prevent and control the status.
