生物多样性是人类赖以生存和发展的物质基础,地球上的生物多样性每年为人类创造约33兆美元的价值。1然而,近年来,生物多样性收到了严重的威胁,物种灭绝速度不断加快,遗传多样性急剧贫乏,生态系统严重退化这些都加剧了人类面临的资源、环境、粮食和能源危机。二外来物种对生态环境的入侵已经成为生物多样性丧失的主要原因之一。从全球范围来讲,他们对本地物种和生态系统的危害,足以与栖息地的丧失和恶化所带来的危害相比拟。
Biodiversity is the material basis for the survival and development of humankind. Biodiversity on Earth creates an annual value of about 33 trillion U.S. dollars for mankind. However, in recent years, biodiversity has received grave threats, exacerbating species, rapid and poor genetic diversity, and serious degradation of ecosystems have exacerbated human, resource, environmental, food and energy crises. Invasion of two exotic species to the ecological environment has become one of the major causes of the loss of biodiversity. Globally, their damage to native species and ecosystems is comparable to the damage caused by habitat loss and deterioration.
