| Abstract: | Concept of biological invasion,pasture species introduction and exotic weeds invasion have been introduced.Exotic weeds with harmfulness have been reviewed.Cause of biological invasion :difficult to evaluate the latent risk of pasture invasion which induces to blindnessful introduction;pasture possesses the biological characteristics of invasive weeds;principle of climate comparability is propitious to pasture turning into invasive weeds;absence of natural enemy control is propitious to pasture turning into invasive weeds;planting system is propitious to pasture turning into invasive weeds. |
