    Abstract:
    Objective:The distribution and sensitization characteristics of the pollen of artemisia were analyzed in the grasslands of Inner Mongolian. Method:A face-to-face questionnaires survey about the distribution and sensitization characteristics of the pollen of artemisia was performed together with pollen skin prick tests（SPTs） and measurements of the daily pollen count in 6 region（Xilinhot, Erenhot, Duolun, Tongliao, Jarud, Kailu） in the grasslands of Inner Mongolian. Result:A total of 6043 subjects completed the study. The prevalence of artemisia hay fever was 14.38%（869/6043）. The highest prevalence was found in the 18-39 age group（43.27%, 376/869）. Subjects from urban areas showed higher prevalence of AR than from rural areas（61.22% vs. 38.78%, P<0.01）. There were significant regional differences in the prevalence of AR（P<0.01） among the six areas investigated. The main clinical symptoms of artemisia hay fever were sneezing（96.78%） and itchy nose（91.60%）. The main clinical symptoms of ocular were itchy（68.58%）. Among associated symptoms of artemisia hay fever, fatigue and somnolence were common. The peak season of artemisia hay fever was in August. The season of onset of artemisia hay fever coincides with the peak time of pollen dispersal of artemisia. The SPT positive of artemisia pollen in the investigated 6043 people was 23.98%. Among comorbidities, allergic conjunctivitis accounts for 70.77% （615）, food allergy accounts for 85.85% （746）, asthma accounts for 9.55% （83）. Conclusion:The prevalence of artemisia hay fever in grassland of northern china stays at a high level. It is very important to control artemisia hay fever. 目的：对内蒙古草原地区蒿属花粉的分布及致敏特征进行分析。 方法：通过面对面问卷调查、皮肤点刺试验、花粉监测调查了内蒙古草原6个地区（锡林浩特、多伦、二连浩特、通辽、扎旗、开鲁）蒿属花粉的分布和致敏特征。 结果：内蒙古草原地区6043人完成了问卷调查和皮肤点刺试验。蒿属花粉症的患病率是14.38%（869/6043）；高发年龄在18~39岁年龄段，占43.27%（376/869）；城市的患病率明显高于农村（61.22% vs.38.78%，P<0.01）；6个地区患病率差异有统计学意义（P<0.01）。蒿属花粉症的主要症状以打喷嚏（96.78%）、鼻痒（91.60%）明显，眼部症状中以眼痒（68.58%）明显；其他相关症状突出表现在乏力（31.07%）和嗜睡（30.49%）。蒿属花粉飘散高峰期为8月份；蒿属花粉症患者发病季节与蒿属花粉播散的高峰期时间相吻合。6043例人群中蒿属花粉皮肤点刺阳性率为23.98%，蒿属花粉症合并疾病中，合并结膜炎615例（70.77%），合并食物过敏746例（85.85%），合并哮喘83例（9.55%）。 结论：中国北方草原地区蒿属花粉症的患病率较高，防治蒿属花粉具有重要的意义。.
