摘　　要：薇甘菊是广州最主要的林业有害入侵植物之一。基于广州薇甘菊的实际调查数据及其对应的14个环境因子的定量关系,利用主成分分析确定主要影响因子,据此结合GIS预测其潜在分布区。结果表明:海拔、年平均温度、年均日照时数、以及降水因子年平均降水量、最湿季度降水量、最干季度降水量这6个因子对薇甘菊的分布影响最大。薇甘菊的高度适生区为黄浦区、萝岗区;适生区分布在广州南沙区、天河区,以及增城市、从化市、番禺区局部地区;荔湾区、海珠区以及番禺和从化局部地区为非适生区。广州96%以上的区域均适合薇甘菊的生长,潜在分布区与实际分布区有较好的对应。Mikania micrantha is one of the leading harmful and invasive forestry plants in Guangzhou.We selected 14 environmental factors and determined their quantitative relationship with the actual distribution of the specie in Guangzhou.By using principal component analysis,we determined main influencing factors.Based on the results,we estimated the potential distribution of Mikania micrantha.Results show that： six factors including elevation,mean annual temperature,annual mean sunshine duration,mean annual precipitation,wet quarter precipitation,dry quarter precipitation importantly affected the distribution of M.micrantha.The most suitable normal region was Huangpu,Luoguang;suitable normal region was Nansha,Tianhe and parts of districts of Zengcheng,Conghua and Panyu;unsuitable area was Liwan,Haizhu,small area of Panyu and Conghua.Above 96% area of Guangzhou was suitable for the growth of M.micrantha.And the potential distribution matched actual distribution.
