摘　　要：通过野外调查,结合文献资料,对广州南沙黄山鲁森林公园入侵植物的种类、生活型、生境状况、入侵途径以及危害状况等进行了初步研究.结果表明:黄山鲁森林公园现有外来入侵植物30种,隶属14科29属,其中禾本科(6种)、菊科(7种)植物占总入侵植物种数的43.3%.对入侵植物的生活型分析发现,陆生草本植物最多(21种),其次为灌木(4种)、藤本植物(3种),乔木和水生草本种类最少(各1种),入侵植物主要生长在受人为干扰较大的区域.此外,对入侵植物生长特性及分布等生态学特征分析,可将其对黄山鲁森林公园生物多样性危害程度大致分为3级,其中危害严重的有7种,危害中等的有9种,危害较轻的有14种.从原产地分析来看,15种来自于热带美洲地区,占入侵植物种类总数的50%.Based on field investigation and literature research,the species,life form,growth situation,the ways of invasion and hazard situation of invasive plants in Huangshanlu Forest Park were preliminarily studied.The results showed that there were thirty species of alien invasive plants belonging to 29 genera of14families in Huangshanlu Forest Park.Of them,six alien invasive plant species belong to Poaceae and seven belong to Asteraceae,occupying 43.3% of the total number of invasive plants.Analysis of the life form showed that the most dominant plants were terrestrial herbs（21species）,then shrubs（4species）,vines（3species）,trees and aquatic herbs（1species respectively）,all of them mainly growing in the heavily disturbed areas.In addition,with the analysis of growth characteristics and distribution of ecological traits in the field,seven alien invasive species were evaluated to be at the highest degree of threat to the local biodiversity,nine at the medium,and fourteen at the lowest.Based on the origin,15 species from Tropical America,occupied 50% of the total alien invasive species in Huangshanlu Forest Park.
