【Abstract】 Thirty-four alien invasive species (AIS) including 11 species of animals and 23 species of plants in Beijing were numerated in the present paper through field and literature investigations. Their distribution ranges and damages were briefly listed. Some severe damaging species should be controlled and deracinated at the early stage of their invasion. The environmental impact assessment and risk analyses of some species should be conducted before they are introduced or applied. And some AISs that are causing severe damages in the regions surrounding Beijing should be monitored, and measures should be taken to prevent them from entering Beijing. The control strategies to AIS were discussed.更多还原
