目的调查潍坊市气传花粉的种类、数量和季节消长规律,为本地区花粉症的诊断与防治提供依据。方法应用叶氏重力采样器,于2014年7月1日至2014年10月31日对潍坊市气传花粉浓度进行检测,并对花粉数量进行统计学分析,调查结果与1986年度潍坊市气传花粉浓度进行对比分析。结果本次调查共曝片123张,共收集花粉1 318粒,归属于6科、5属,其中以葎草属(40.14%)、苋科(24.96%)多见,其次依次为蒿属(22.61%)、藜科(3.71%)、禾本科(3.41%)、悬铃木属(2.05%)、酸模属(1.52%)等。总数比1986年同期减少了84.85%;种类比1986年同期增加了3科,减少了14属、5种。结论葎草属、苋科、蒿属、藜科是目前潍坊市夏秋季节最主要的气传花粉,占潍坊市夏秋季气传花粉总数的91.42%。
Objective To investigate the species, quantity and seasonal variation of airborne pollen in Weifang, and to provide evidence for the diagnosis and prevention of hay fever in this area. Methods The leaf mass gravity sampler was used to detect the concentration of pollen in Weifang City from July 1, 2014 to October 31, 2014. The pollen quantity was statistically analyzed. The results of the survey were in line with those of Weifang City in 1986 Pollen concentration for comparative analysis. Results A total of 123 pieces of pollen were collected in this survey. A total of 1 318 seeds of pollen were collected and belonged to 6 families and 5 genera, among which Rubus (40.14%) and Amaranthaceae (24.96%) were more common, followed by Artemisia 22.61%), Chenopodiaceae (3.71%), Poaceae (3.41%), Platanus (2.05%), Acid mold (1.52%) and so on. The total number decreased by 84.85% over the same period of 1986; the number of species increased by 3 families over the same period of 1986, a decrease of 14 genera and 5 species. Conclusion The genus Rubra, Amaranthus, Artemisia and Chenopodiaceae are the most important airborne pollen in the summer and autumn in Weifang City, accounting for 91.42% of the total number of airborne pollen in summer and autumn in Weifang.
