生物多样性是维持生态系统相对平衡的必要条件,是人类赖以生存的物质基础,某些物种的消亡可能引起整个系统失衡甚至崩溃。外来生物入侵直接破坏了生物的多样性,更给国家带来了巨大的经济损失。
Biodiversity is a necessary condition for maintaining the relative balance of ecosystems and is the material basis for human survival. The demise of certain species may cause the entire system to become unbalanced or even collapse. Invasion of alien organisms directly destroys the diversity of organisms and brings huge economic losses to the country.
