广州白云山外来入侵植物初步研究

A Preliminary Study on the Alien Invasive Plant Species in Baiyun Mountain,Guangzhou

据初步调查统计,广州白云山共有外来入侵植物15科29属29种,以草本植物为主.危害较大的外来入侵植物有薇甘菊(Mikania micrantha)、五爪金龙(Ipomoea cairica)、马缨丹(Lantana camara)、美洲蟛蜞菊(Wedelia trilobata)等.外来入侵植物常见于受人为干扰的生境,如荒地及路旁等.这些植物通过自然力量、人为有意引种、无意带入等途径入侵到白云山.为控制白云山外来入侵植物,建议:开展宣传教育,提高公众意识;加强对开发后的地方进行整理;加强对外来入侵植物的监测等.

Based on our investigation, 29 species of alien invasive plants belonging to 29 genera, 15 families were recorded in Baiyun mountain, Guangzhou. Most of them were herbs. Mikania rnicrantha, I pornoea cairica, Lantana camara, and Wedelia trilobata etc. were important invasive species. Alien invasive species were most prominent in human-disturbed habitats, such as wasteland and roadsides. These species were transported by natural force, transplanted purposefully or by accident. To control these alien invasive species in Baiyun mountain, some suggestions are brought forward： to strengthen education and enhance the consciousness of people for avoidance of species invaded; to tidy up the places after being developed; to enhance the monitoring to alien invasive plant species;investigation.
