| 为探究朱顶红花叶病毒(Hippeastrum mosaic virus, HiMV)在全球的潜在地理分布, 基于HiMV在全球的分布数据, 运用MaxEnt模型与ArcGIS 10.2空间分析软件预测HiMV在历史和未来的2个不同气候场景条件下(低强迫场景SSP126?高强迫场景SSP585)的潜在地理分布?MaxEnt模型的测试者特征(receiver operating characteristic, ROC)曲线下面积(area under curve, AUC)为0.940, 预测结果可靠性高?对HiMV分布有重要影响的环境因子是:最干季均温(bio 9)?最湿月降水量(bio 13)?最干月降水量(bio 14)?最湿季均温(bio 8)和月平均昼夜温差(bio 2)?在历史气候条件下, HiMV在欧洲?中美洲及南美洲中南部?亚洲南部?大洋洲及非洲中部广泛适生; 在我国除新疆?青海?甘肃西部?内蒙古?黑龙江?吉林?西藏及四川西部以外的地区适生; 在未来气候情景下, HiMV分布在欧洲呈现向东扩的趋势, 在我国的适生区可向北延伸至吉林?黑龙江? |

| To investigate the potential global geographical distribution of Hippeastrum mosaic virus (HiMV), the MaxEnt model combined with ArcGIS 10.2 software were used to predict its potential geographical distribution under historical and future climate scenarios (low-stress scenario SSP126 and high-stress scenario SSP585). The results showed that the MaxEnt model’s receiver operating characteristic (ROC) curve had an area under curve (AUC) of 0.940, indicating high predictive reliability. The significant factors affecting the distribution of HiMV were mean temperature of driest quarter (bio 9), precipitation of wettest month (bio 13), precipitation of driest month (bio 14), mean temperature of wettest quarter (bio 8), and mean diurnal range (bio 2). Under historical climatic conditions, HiMV was widely suitable in Europe, Central and South America, South Asia, Oceania, and Central Africa. In China, suitable areas included most regions except Xinjiang, Qinghai, Inner Mongolia, western Gansu, Heilongjiang, Jilin, Xizang, and western Sichuan. Under future climatic conditions, the distribution of HiMV is expected to expand eastward in Europe and northward in China, reaching Jilin and Heilongjiang. |
