全球环境变化与生物入侵

全球环境变化将对地球生态系统的物种多样性及其分布产生重要而深远的影响:一方面可能使部分地区的生态系统对外来物种的抗性弱化;另一方面将激活外来物种的活性,导致外来生物的快速扩散和大规模入侵,进而排挤和"杀死"当地乡土物种,减少生物多样性,改变原有生态系统的组成、结构和功能.提出了加强对入侵物种的预测、监控,以及立足于生态系统和整个社会来应对生物入侵的策略,以期为预防和控制生物入侵提供参考.

Global Environmental Change and Biological Invading

Global environmental change will heavily impact the species diversity of global ecosystem and its distribution. Global environmental change may lead to weakening resistance to adventive species in some parts of the ecosystem. Moreover, it may activate the activity of invasive species and lead to the rapid prolif- eration of alien organisms and large-scale invasion, which can exclude and kill native species, even reduce biological diversity and change the composition, structure and functions of original ecosystem. Strategies were suggested to enhance the prediction and supervision of invasive species and cope with them based on the whole ecosystem and society, which will provide references for prediction and control of biological inva- sion.
