摘要
生态入侵的途径主要有 4种 :自然传播、贸易渠道传播、旅客携带物传播和人为引种传播。生态入侵不仅会导致生物多样性丧失 ,而且会带来巨大的经济损失 ,因此要严格执行《进出境动植物检疫法》 ,加强生态学知识的普及与宣传 ,并对引种进行生态风险评价 。
The ways of Ecological invasion include: natural dissemination,trade channel spread, things carried propagation and exotic species introduction. Ecological invasion not only leads to loss of biodiversity but also brings about giant loss in property. Therefore 《Law of people's Republic of China on the entry and exit animal and plant quarantine》should be carried out strictly. Ecological knowledge should be disseminated and propagated and Ecological risk of exotic species introduction should be estimated.So that probabilities of ecological disaster reduce to lowest.
