摘　　要：花粉过敏极度容易受到外界环境的影响。本文梳理了气象因素、空气污染物、城市化进程等环境因素改变对花粉量、花粉季节持续时间、花粉致敏性强弱的影响。大气中CO2浓度和全球温度升高导致花粉产量增加,花粉季节延长以及花粉致敏性增强;空气污染物吸附在花粉表面,改变其物理结构和化学性质,促进花粉过敏原释放;城市化进程改变使得城市花粉过敏率比农村地区高。通过加强花粉监测,完善花粉预报体系来更好地应对环境改变引起的花粉过敏这一公共卫生挑战。Pollen allergy is extremely susceptible to external environmental influences. In this paper, we sort out the effects of changes in environmental factors such as meteorological factors, air pollutants, and urbanization on pollen production, pollen season duration, and the strength of pollen sensitization. The rising atmospheric CO2 concentrations and global temperatures increased pollen production, prolonged pollen seasons, and enhanced pollen sensitization;air pollutants adsorbed on pollen surfaces, altering their physical structure and chemical properties and promoting pollen allergen release;and changes in urbanization processes have resulted in a higher rate of pollen sensitization in cities than in rural areas. The public health challenge of pollen allergy caused by environmental change can be better addressed by strengthening pollen monitoring and improving pollen forecasting systems.
