Effects of Biological Invasions on Stabilization of Agricultural Ecosystem and Its Strategy of Prevention and Control

Biological invasions are unintended consequences of globalization, which facilitates the transglobal movement of species across all geographical and physical boundaries with the vastly increasing movement of people and commercial goods. In addition to economic impacts, they have profound influence on native biodiversity, communities, ecosystems and even regional ecological security. Biological invasions, global changes and habitat loss constitute the three most pressing environmental problems in the 21st century. In this review, the general status, the definition, the pathways and the process of biological invasions are explained. Especially, the effect of biological invasions on the stabilization of the agricultural ecosystem is clarified. At the same time, strategies of prevention and cure on biological invasions are put forward.
