| Abstract: | Based on our survey on the exotic plants of Shandong Province, there are total 827 alien species, which is 39.03% of total wild plants. Among them, 41 species are harmful or harmful potentially, and some of them are reported in this paper. The composition, origins, growth form and habitat of exotic plants in Shandong are discussed too. The results shows that:(1) 348 species were imported from other countries, and there is high proportion of exotic species root in America, Asia and Europe;(2) the invisibility and harmful degree of trees are less serious than those of climbs and herbs;(3) habitat of exotic shows correlation with human disturbance. |
