动植物检疫在生物多样性保护中的作用

生物多样性保护不仅包括对野生物种的保护，也包含对栽培和驯化物种的遗传多样性的保护，动植物检疫在保护栽培和驯化物种的安全和防止野生物种资源外流两个方面发挥了重要作用。可以认为，动植物检疫系统是生物多样性保护中的一支生力军。文章强调，一要加强动植物检疫，减少国际贸易对生物多样性的影响；二要增强口岸把关，有效地保护我国濒危、珍稀物种资源。文中例举了过去我国濒危、珍稀生物资源破坏和流失情况，并介绍了在加强对濒危、珍稀物种进出口管理中，动植物检疫机关所起的把关作用。

The role of animal and plant quarantine in the protection of biological diversity

The protection of biological diversity is not only to safeguard the wild species, but also to conserve the clutivated and domesticated ones. The animal and plant quarantine plays an important role both in safeguarding the cultivated and domesticated species and in preventing their outflow. It should be recognized that the animal and plant quarantine system is actively involoved in the protection of biological diversity. The author emphasized that firstly, it is necessary to strengthen the animal and plant quarantine system so as to reduce the effect of international trade on biological diversity, secondly, to intensify the quarantine safegurd on ports of entry to protect the endangered and rare species. Examples are given to illustrate the destruction and loss of rare biological resources resulted from the species outflow in international trade in the past years, and reviewed the role of animal and plant quarantine in strengthening the management of endangered and rare species.
