Abstract：Pollen allergy is a global health problem which also has attracted much attention in China, and the incidence is increasing in the northern area. The data of daily airborne pollen concentration, meteorological conditions, vegetation growth and allergic patient were analyzed from 2017 to 2022 in Hohhot of Inner Mongolia Autonomous Region. There were two peaks of pollen dissemination every year. The first peak was in early April, which was a greater proportion of woody plant pollen, with a short duration. The second peak was from August to September, mainly composed of herbaceous plants pollen such as Artemisia of Compositae pollen, with a long duration and had much more serious sensitization effect. The results showed that the effective accumulated temperature of ≥5°C from January to June was significantly negatively correlated with the start date of the peak pollen dispersal period, while the cumulative precipitation and cumulative sunshine hours from the early stage to the flowering period were significantly positively correlated with the end date of the peak pollen dispersal period. The higher the accumulated temperature was, the earlier the peak period of pollen dispersal started. The end date of peak period would be delayed by the large amount of precipitation and light hours, meanwhile the number of pollen dispersal would increase. There were statistically significant or significant positive correlation between the cumulative value of each meteorological factor or the vegetation index and the monthly average pollen concentration. Appropriate light hours and precipitation, the vegetation would grown well, which would promote pollen dispersal and stimulate an increase in concentration. The number of Allergic Rhinitis patients was consistent with the variation of pollen concentration, and was reaching a peak in August. When the pollen concentration exceeds 100 grains/1000mm2, there was a lag period of 0~4days in the peak of AR treatment, among which the most obvious incremental effect was after 2 days. The number of patients was exponentially related to the pollen concentration in a ten-day time range. The above results would provide some practical reference for pollen concentration meteorological forecasting services and the prevention and treatment of AR caused by pollen allergy.<
