尽管动植物一直在地球仪上传播，扩大它们的活动范围，入侵新的领土，但人类文明却把这些生物入侵加速到了一个非同寻常的程度。非本地物种对自然系统的完整性构成了重大威胁，因为它们可以改变营养状况，发展成单一栽培，并使本地物种灭绝（例如，固氮树杨梅[Vitousek and步行者1989]、斑马贻贝Dreissena polymorpha [米尔斯et al. 1994，Roberts 1990]、紫色千屈菜[美世1990]和棕色树蛇Boiga irregularis [Burdick 1994]）。尽管美国政府认识到非本土物种带来的风险，并且近世纪来一直在制定旨在减少危害的立法，
A though plants and animals have always spread across the globe, expanding their ranges and invading new territories, human civilization has accelerated these biological invasions to an extraordinary degree. Nonindigenous species represent a major threat to the integrity of natural systems, because they can alter nutrient regimes, develop into monocultures, and drive native species to extinction (e.g., the nitrogen-fixing tree Myrica faya [Vitousek and Walker 1989], the zebra mussel Dreissena polymorpha [Mills et al. 1994, Roberts 1990], the purple loosestrife Lythrum salicaria [Mercer 1990], and the brown tree snake Boiga irregularis [Burdick 1994]). Although the US government recognizes the risks posed by nonindigenous species and for nearly a century has had legislation in place aimed at reducing harm-
