摘　　要：目的明确呼和浩特城区气传致敏花粉的种类、含量及播散规律。方法采用Durham花粉取样法,收集2018.3-2018.10期间花粉粒,在光学显微镜下鉴定花粉种类。结果8个月中,共收集花粉总数61308粒,其播散呈现出2次花粉高峰期,分别在3~5月及8~9月,4月份收集花粉总数高达18420粒(30.05%),9月份收集花粉总数高达20064粒(32.72%),且秋季高峰期花粉总数较春季增多。花粉分布有明显的种属差异,春季以桦木属(28.64%)、丁香属(7.36%)、松科(6.71%)为主;秋季以蒿属(28.66%)、禾本科(17.44%)、蔷薇科(3.07%)为主。结论2018年花粉分布呈2次高峰,高峰期优势种属分布为桦木属和蒿属。Objective This study aimed to identify the species, quantities, and distribution of airborne allergenic pollens in the urban district of Hohhot city. Methods Daily airborne pollen was monitored using the Durham gravitational method from March 1 to October 31, 2018, and the species of airborne allergenic pollens were identified by optical microscopy. Results A total of 61,308 grains of airborne allergenic pollen were collected over 8 months. The peak of airborne allergenic pollen grains appeared from March to May and from August to September. A total of 18,420 pollen grains(30.05%) were collected in April and 20,064(32.72%) in September. In addition, the total number of pollen grains in the autumn peak increased than that in the spring. There were significant species and genus differences in pollen distribution. In spring, the main pollen species were birch(28.64%), clove(7.36%), and pine(6.71%),whereas in autumn, the main pollen genera were Artemisia(28.66%), Gramineae(17.44%), and Rosaceae(3.07%). Conclusion In 2018, the airborne allergenic pollen distribution showed two peaks, and the dominant species and genera at the peaks were birch and Artemisia.
