摘　　要：2017年小麦条锈病在我国大范围流行,为明确大流行年份小麦条锈病时空动态,本研究通过在全国小麦主产省区定期调查小麦条锈病发生情况,并在总结2017年我国小麦条锈病流行特点的基础上,分析了小麦条锈病在县域水平随时间发展及其在空间上的分布和动态。结果表明,2017年小麦条锈病在我国黄淮海麦区大范围流行,发生面积达555.66万hm2,主要发生麦区平均病叶率为2.70%~40.00%、病害严重度为7.6%~45.2%、病害扩散速率为0.007~0.140;病害发生范围波及全国18个省(区、市)866个县,向北扩散至北纬41°的内蒙古五原县,向东扩散至东经121°的山东省烟台市和威海市。In order to clarify the spatiotemporal patterns of wheat stripe rust in the pandemic year of2017, the characteristics and spatiotemporal dynamics of the disease were summarized and analyzed at the county level based on the investigation of occurrence in major wheat-producing provinces. The results showed that wheat stripe rust was widespread with an area of 5.56 million hm2 mainly in HuangHuai-Hai area of China in 2017. The incidence of the disease in main wheat-producing areas ranged from 2.70% to 40.00%, the disease severity was 7.6%-45.2%, and the epidemic rate ranged from 0.007 to 0.140. The disease was found in 866 counties in 18 provinces, and spread northward to Wuyuan, Inner Mongolia at 41°N and eastwards to Yantai and Weihai, Shandong Province at 121°N.
