Exotic Species Invasion and Ecological Safety
Abstract:At present,biodiversity of the world has been menaced.Biological invasion has been one of the factors threatening biodiversity.In the field of the international ecology,ecological invasion of exotic species has become a new hot issue. In recent years,exotic species invasion has done harm more and more seriously to China's biodiversity,and it has threatened China's ecological safety.Some concepts related to biological invasion are introduced.Invasive ways of exotic species,the serious impacts of invasive species on ecological environment,biodiversity (including species and genetic diversity),economy and society are reviewed.In order to prevent and control biological invasion and to guarantee China's ecological safety,it is necessary,based on the actual situation of exotic species invasion in China,to focus on the improvement of the state capacity,research capacity and management capacity to deal with biological invasion.
Keywords:Exotic species  Biological invasion  Prevention and management strategy  Biodiversity  Ecological safety
