摘　　要：收集南方10省25个地理种源,在福建明溪县进行观赏型南方红豆杉地理种源实验。通过对观赏型南方红豆杉的2年生幼树的树高、地径、冠幅、一级侧枝数量、冠幅生物量鲜重、根系生物量鲜重等评价性状的测量分析,研究种源的地理变异。结果表明:其树高、地径、冠幅、一级侧枝数量、冠幅生物量鲜重、根系生物量鲜重等指标存在显著性差异.利用多目标决策方法进行地理种源评价,选择出福建明溪、贵州梵净山等2个观赏型南方红豆杉的优良地理种源。In order to examine geographical variations, saplings of 2-year-old Taxus chinensis var. mairei from 25 geographical provenances were collected from 10 provinces in Southern China to select those that are suitable for landscape purposes. The experiment was carried out in Mingxi County, Fujian, China by the measurement of tree height, ground diameter, crown breadth, number of lateral branch, the fresh weight of crown breadth biomass and the fresh weight of root biomass. The results showed there existed significant differences among the sampling saplings from different locations in tree height, ground diameter, crown breadth, number of lateral branch, the fresh weight of crown breadth biomass and the fresh weight of root biomass. Two superior geography provenances of landscape T. chinensis var. mairei were selected out by the method of multiple objective desion,i, e. ,one from Mingxi of Fujian and the other form Fanjing Montain of Guizhou.
