摘要
生物入侵是一个影响深远的全球性问题 ,其对我国的生态系统、环境和社会经济的影响也日益明显。生物入侵不仅导致生态系统组成和结构的改变 ,而且能彻底改变生态系统的基本功能和性质 ,最终导致本地种的绝灭、群落多样性降低 ,并给社会经济造成重大损失。本文还分析了全球变化与当前生物入侵加剧的关系 ,由此提出加强对入侵种的预测和监控及立足于生态系统和整个社会来应对外来生物入侵的策略 。
Biological invasion has become an important element of global changes. It also has an obvious increasing impact on the evaded ecosystem, environment and social economy of China. Biological invasion not only leads to the conversion of the components and reconstructions of ecosystem, but also alters its basic functions and characteristcis, resulting in the extinction of native species and loss of community biodiversity, and causing significant damage to social economy as well. This paper also analysed the relation between global changes and the current quickened pace of biological invasion. 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 a powerful promotion in prediction and control of biological invasion.
