摘　　要：采用重点普查与野外路线调查相结合的方法,对滇池北岸已建成的6个湿地公园的所有园林植物进行了4轮调查.通过构建“生态风险预评价体系”对所有园林植物外来种进行筛选,筛选出具风险隐患且相关法规和研究尚未确定其为恶性入侵的园林植物外来种作为待评价目标.通过层次分析法构建“生态风险评价体系”,对待评价种进行生态风险评价.结果表明:滇池北岸园林湿地园林植物外来种共计121种,隶属于57科99属,以多年生草本为主.在通过预评价体系筛选出的48种园林植物外来种中,风险极高的园林植物外来种有2种,风险较高的园林植物外来种有3种,风险中等的园林植物外来种有21种,风险较低的园林植物外来种有20种,风险极低的园林植物外来种有2种.根据园林植物外来种在园林绿化中的特殊作用和不同的生态风险等级对其提出了防控对策和建议.A combination of key census and field route surveys was conducted in 4 rounds of surveys on the plants in the 6 wetland parks built on the north bank of Dianchi Lake.Through the establishment of an“ecological risk pre-assessment system”,all exotic species of garden plants are screened,and exotic species of garden plants that have potential risks and have not been identified as malignant invasion by relevant laws and regulations are selected as targets to be evaluated.The“ecological risk assessment system”was constructed by analytic hierarchy process to evaluate the ecological risk of the selected species.The results showed that there were 121 exotic species of garden plants in the wetland on the north bank of Dianchi Lake,belonging to 57 families and 99 genera,mainly perennial herbs.Among the 48 exotic species of garden plants selected through the pre-evaluation system,there are 2 species of garden plants with extremely high risk,3 species of garden plants with high risk,and 21 species of garden plants with moderate risk.There are 20 exotic species of garden plants with low risk,and 2 exotic species of garden plants with extremely low risk.According to the special role of exotic garden plants in landscaping and different ecological risk levels,prevention and control countermeasures and suggestions are put forward.
