内蒙古外来植物入侵风险评价

Risk assessment of alien invasive plants in Inner Mongolia

基于内蒙古生物入侵防控及外来物种管理的需求,对内蒙古外来植物的种类组成和入侵现状进行了调查。结果表明:目前内蒙古外来植物共55种,隶属于17个科;构建了适应于内蒙古地区生态环境特点和经济社会发展特征的外来植物入侵风险评估指标体系,通过对内蒙古53种主要的外来植物进行入侵风险评价,确定其风险等级,提出相应的管理策略,从而为内蒙古地区外来植物入侵的防范和生态安全提供有利保障。

Based on the demands for preventing, controlling, and managing the invasion of alien species in Inner Mongolia, an investigation of species composition and invasion status of alien plant species in Inner Mongolia was conducted. There are a total of 55 alien plants belonging to 17 families. We established a risk assessment indicator system that could be adapted to the characteristics of ecological, economic and social development of Inner Mongolia. Using this indicator system, the invasion risks of 53 alien plant species were evaluated and the levels of the invasion risks were assessed. For each risk level, the corresponding risk management strategies were presented. Our results provide a favorable guarantee for prevention and control of alien plants and consequently the ecological security in Inner Mongolia.
