摘要
现代生物入侵现象日益严重,一门新的生物学部门——入侵生物学运用而生。入侵生物学对生物入侵的定义是某种生物从原来分布的区域扩张到一个新的地区,在新的地区内过度繁殖、扩散并持续下去。入侵种和本地植物竞争空间和食物,破坏栖息地和食物网,降低水质,并且传播疫病和寄生虫,从而使当地经过长期进化形成的稳定生态系统遭到破坏,对入侵地的农、林、牧、渔业造成很大的影响,病原体致病微生物的传播则直接威胁当地居民的健康。入侵生物学要解决的核心问题是:什么样的物种才会成为入侵种和什么样的群落才容易被入侵。因为生物入侵现象的复杂性,入侵生物学的研究进展较缓慢,尚处在积累经验和资料的初步阶段,还有待进一步的从多学科角度开展综合性的研究。
Now, biological invasion is becoming more and more serious, which causes the emerge of a new subject：Invasion Biology. Biological invasion is the biological expansion of a certain organism from its original distribution region to a new area, and is sustained with excessive reproduction. Invasive species compete with native species for space and food, do great damage to habitats and food nets, reduce water quality, spread diseases and parasites, and in the end destroy the stability of local ecological system formed over a long evolution, and so will be greatly affecting agriculture, forestry, animal husbandry, and fishery in the intrusion area. And the dissemination of pathogenic microorganisms is also a direct threat to the health of local residents. The core problem of invasion biology is to find what kinds of species are invasive and what kinds of communities are vulnerable. Because of the complexity of biological invasion, the research of invasion biology is still on the initial stage of experience and data accumulation, and needs to be further studied from a multi-disciplinary perspective.
