摘要
本研究从入侵性、适应性、扩散性和危害性4个准则层及其22个指标层分析了飞机草的入侵风险,并运用风险评估的方法对其生态风险进行初步研究,提出了飞机草风险评估体系以及判断标准,其结果表明:飞机草的综合风险指数为74.5,属于高风险外来植物,应严格禁止在我国各地区之间的引入。
The invasion risk of Chromolaena odorata were analyzed by four criterion laygrs including invasiveness, adaptability, diffusivity and harmfulness, and 23 index layers. The ecological risks were also discussed through risk evaluation. The risk assessment system and criterion is put forward in this study. It provides effective means for forecasting hazard and managing risk of Chromolaena odorata. The results showed that the comprehensive risk value of Chromolaena odorata was 74.5. It exhibit that this weed was high risk exotic plant and should not be allowed to introduce in different regions.
