摘　　要：根据三裂叶豚草的生长特性和我国气候特点,对三裂叶豚草在我国的适生区进行划分;采用风险性评估量化指标体系,建立了一、二级评判标准的计算模型,分析了三裂叶豚草传入我国的风险.结果表明,三裂叶豚草的危险性综合评价的风险值R为2.18,属于高风险外来有害生物.确定了三裂叶豚草的适生区,同时,提出了对三裂叶豚草的风险管理措施.The potential risk regions of Ambrosia trifida L. were estimated according to growth characters and historical meteorological data. Calculation models to judge the first grade and the second grade criterion estimation were established on the base of its criteflon of PRA assessment and quantitative analysis, and the risk of A. trifida L. introduced to China was analysed. The results showed that its comprehensive estimation risk value was 2.18, which suggested that it belonged to high risk exotic harmful organism. The potential risk regions were estirnated, and the risk management for controlling A. trifida L. was evaluated.
