摘　　要：[目的]排除外来入侵植物对维持孔林自然景观和生态平衡的潜在隐患,保护孔林本地植物的多样性和维护孔林生态的和谐发展。[方法]采用实地观察、样品采集和标本馆标本查阅相结合的方法,对孔林入侵植物的种类、分布情况进行全面调查和总结。[结果]发现孔林内共有入侵植物16种,隶属11科15属,其中56%的种类原产地为美洲,现多以归化的一般杂草形式出现。[结论]就总体分布格局来看,16种入侵植物多以零散或小种群分布的状态存在,目前还没有对孔林植被造成严重破坏,但垂序商陆、小蓬草、一年蓬和裂叶牵牛对生态平衡的潜在威胁明显,值得引起相关部门注意并制定切实有效的防范措施。[ Objective] In order to protect local plants diversity and maintain the balanced development of the ecological system of the Forest. [ Method] The invasive status of alien plants, including their flora and distributions, was completely investigated and summarized by using field observing, plant sampling, and herbarium specimen consulting. [ Result] A total of 16 invasive plants belonging to 11 families and 15 genera were found in the Forest. And 56% of the species were originated from American, but now had been domesticated locally. In addition, the invasive plants in the forest were mostly distributed at scatter sites or within small populations. [ Conclusion] 16 species have not produced very serious damage on local vegetation presently, but potential threatens derived by some species, such as Phytolacca americana, Conyza canadensis, Erigeron annuus, and Ipomoea nil are emerging. These potential risks should be paid attention by the related management departments, and some necessary, precaution measures should also be taken in advance.
