摘要
为探索滇西北外来入侵植物现状及其区域入侵风险,提高区域应对外来入侵植物管控水平和能力,对滇西北维西县境内普查收集到的62种外来植物的空间分布、危害发生程度、物种区系统计结果以及调查发现频度等相关数据信息进行整理分析,提出外来植物入侵风险评估模型和方法,并对记录到的外来植物分别进行入侵风险评估。结果表明,62种外来植物中有52种入侵植物,其中二级入侵中风险水平植物有13种,占比25%;三级入侵低风险水平植物有39种,占比75%;不存在一级入侵高风险植物。针对各物种入侵风险评估等级,提出采用分级分类管控方法对外来入侵植物进行风险评估和管控,并就外来物种入侵风险管理措施进行讨论。
In order to explore the current situation and regional risks of invasive plants in northwest Yunnan,and improve the level and ability of regional control against invasive plants,the data of spatial distribution,degree of harm,species flora and investigation frequency of 62 invasive plants collected from the census in Weixi County,northwest Yunnan was sorted and analyzed.A risk assessment model and method for invasive plants were proposed,and invasive risk assessments were conducted on the recorded invasive plants separately.The results showed that there were 52 invasive plant species among 62 species of exotic plants,including 13 species at risk level of secondary invasion,accounting for 25%,and 39 species with low risk level of tertiary invasion,accounting for 75%;there was no high risk plants of primary invasion.According to the invasion risk assessment level of each species,the classification control method was proposed to assess and control the risk of invasive plants,and measures for managing the risk of invasive species were discussed.
