摘  要:
To date, it has been discovered that there were 108 species of exotic weeds belonging to 23 families, 76 genera in China. The origins of exotic weeds in China are of diversity. Among the 108 exotic weeds, most are annual, and some perennial are vicious. The number of newly invading exotic species has quickly increased in recent years. The invading exotic weeds in China are mainly associated with the similarities between their original and the newly colonized areas, their high reproductive capacity and the changes of their genetic diversity. So far, the exotic weeds have caused obvious damages to various ecosystems and social and economic developments. In the present paper, the strategies of how to manage the exotic weeds effectively in China were proposed.
