外来物种入侵对生物多样性的影响及对策

Effect and Prevention Countermeasures of the Intrusive Alien Species on Biological Diversity

生物多样性是人类赖以生存和发展的基础,生物多样性丧失成为人们关注的一个热点问题。外来物种入侵是生物多样性锐减的主要原因之一。外来物种入侵影响遗传多样性、物种多样性、生态系统多样性和景观多样性,从而加快生物多样性的消失速度,应引起人们高度重视。提出了防止外来物种入侵的对策。

The biological diversity was the foundation for humanity to survive and develop, and the forfeiture of the biodiversity had become a hotspot problem. One of the major reasons for the sharp decrease of the biodiversity was the intrusive alien species, The intrusive alien species had influence on genetic diversity, species diversity, ecosystem diversity and landscape diversity, so as to increase the vanishing speed of the biodiversity, Much more attention should be paid. And effective measures should be taken to prevent the intrusion of alien species.
