园林引种生物入侵风险评价——以五叶地锦为例

Risk Evaluation on Biological Invasion of Introduction of Landscaping Plants——A Case Study on Parthenocissus quinquefolia

由于城市园林植物引种工作的特殊性,各种形式的国际间的园艺材料交流活动频繁,使得城市园林植物引种行业成为最有可能造成生物入侵的重要途径之一。为了防控引种可能带来的危害,应进行引种前的生态风险分析。已引物种应进行生态入侵风险评估,建立相应监控对策。文章以长春市园林绿化中应用比较广泛的五叶地锦(Parthenocissus quinquefolia)为例,通过查阅资料等方法,应用外来种入侵的风险评估体系及风险评价标准,对五叶地锦形成入侵的风险性进行了分析,结论为:在长春地区,五叶地锦是高风险入侵性的外来物种。

For the particularity of the introduction of landscaping plants, activities for varies of international horticultural materials intercourse were frequently held. Landscaping plants introduction in city is becoming one of the important ways that probably cause the bio-invasion. In order to prevent detriments from disserving by introduction, ecological risk should be analyzed before introduction. Taking Parthenocissus quinquefolia which are widely used in landscaping in changchun as an example, applying the invasion risk evaluation system of alien species and the invasion risk standard , risk which invaded Parthenocissus quinquefolia were analyzed. The result shows that this plant has high risk to cause bio-invasion.
