摘　　要：结合Maxent生态位模型与地理信息系统(GIS),综合分析影响芡欧鼠尾草生长发育的环境因素,结合原产地分布特征,计算结果经ROC曲线分析法验证,Maxent生态位模型的AUC值为0.933(非常接近1),定量地获得了芡欧鼠尾草在我国的潜在适生区,通过验证试验,其结果与模型基本相符。The growth and development of Salvia hispanica L. were comprehensively analyzed by combining Maxent ecological niche models with geographical information system technique,the ecological environment factors affecting and the distribution features of the protospecies were taken into consideration. The checked result of receiver operating characteristic( ROC) curve analysis showed that the area under curve( AUC) value of Maxent ecological niche models reached 0. 933, the relatively exact potential distribution region of Salvia hispanica L. all over China was obtained quantitatively and intuitively, After verification test, it was basic coincidence betwee the test results and the models.
