<正>世界的生物多样性正受到严重威胁,其中,生物入侵已成为威胁生物多样性的重要因素之一。近年来,外来种入侵对我国生物多样性的危害日益加剧,已经危及到我国的生态安全。为此从介绍与外来种入侵有关的概念入手,分析了外来种入侵的途径,生物入侵对我国生态环境、生物多样性(包括物种多样性和遗传多样性)、经济及社会的严重影响。提出在外来种入侵的防治和管理方面,应根据我国国情和目前生物入侵的实际状况,加强国家能力、研究能力和监管能力建设,确保我国的生态安全。

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.
