| Abstract: | Objective]To further understand the present situation and the data of alien species in Lushan mountain,providing a reference for the management of alien species.Methods]We analyzed and discussed the floristic composition,life form,original place,introduction way of alien species,and invasive alien species in Lushan based on field investigation by route checking method,and related literature study and specimens examination.Result]448 alien plants belonging to 89 families and 309 genera are recorded in Lushan,(1)69 species are within Asteraceae,accounting for 15.4%of the total.(2)Most of the alien plants are herbs and account for the largest proportion(289 species,64.5%),next is arbor(83 species,18.5%).(3)178 alien species mainly came from American,accounting for 39.2%,followed by those with Asian origins(106 species,23.3%),and the proportions of the alien plants originated from European,Africa,Mediterranean and Oceania are all much less.(4)The alien species are mostly introduced for ornamental.(5)115 alien plants have been recorded strongly invasive,accounting for 25.67%of the total.Conclusion]Lushan has a special ecological environment and abundant species of alien plants.Effective measures should be put forward to control them,such as strengthening the supervision and detection,and scientific introduction,increasing the publicity of the harm of alien invasive plants,as well as improving the prevention and control measures of alien invasive plants. |
