摘要
目的探讨南昌城区气传花粉的种类、数量及季节消长规律。方法2000年4月1日-2001年3月31日在南昌城区采用Durham重量法进行为期1a的气传花粉调查,并分析其分布规律。结果南昌城区大气中全年都有气传花粉的飘散,种类达47个种属,以豚草属(35.73%)、松科(15.94%)、蒿属(11.94%)、禾本科(5.88%)、柏科(5.64%)、杉木属(5.12%)、藜苋科(5.03%)、葎草属(2.02%)为主。其飘散存在2次高峰,第1个高峰出现在3、4月,占22.56%及11.98%,以松科、柏科、杉木属、桑科及柳属为主;第2个高峰出现在8-10月,占9.61%,23.77%及19.57%,以豚草属、蒿属、禾本科、藜苋科及葎草属为主。同时发现,禾本科花粉在12个月都有飘散,但其花粉水平并不很高。结论南昌城区全年都有花粉飘散,呈现出2个明显的高峰(3-4月与8-10月),种类以豚草属、松科、蒿属、禾本科、柏科、杉木属、藜苋科、葎草属为主。
Objective To determine species, counts, and seasonal variation of airborne pollen in the center of Nanchang. Methods Pollen counts were done with Durham gravity method on the top of the building in the campus of Jiangxi Medical College, Nanchang, April 1, 2000-March 31,2002. Results There were airborne pollens in all seasons of the year in atmosphere of Nanchang, which included about 47 species. The highest airborne presence (percent of total yearly pollen counts) was for Ambrosia(35.73%); followed by Pinaceae (15.94%), Artemisia (11.94%), Gramineae (5.88%), Cupressaceae (5.64%), Cunningha-mia R.Br.(5.12%), Chenopodium-Amaranthus (5.03%) , and Humulus(2.02%). The dispelling period showed a double curve: the first peak occured in Mar. and Apr. (22.56% and 11.98% respectively). The predominant pollens were tree pollen (Pinaceae, Cupressaceae, Cunninghamia R.Br., Moraceae and Salix). The second peak occured in Aug., Sep., and Oct. (9.61%, 23.77%, 19.57% respectively). The predominant pollens were grass pollen (Ambrosia, Artemisia, Gramineae, Chenopodium-Amaranthus and Humulus). Gramineae had been scattering all seasons, but it's counts were not high in every month. Conclusion There are airborne pollens dispelling in atmosphere of Nanchang in the whole year, whose dispelling period shows a double curve (the first peak occurs in Mar. and Apr. And second peak occurs in Aug. Sep. and Oct.) and the predominant pollens are Ambrosia, Pinaceae, Artemisia, Gramineae, Cupressaceae, Cunninghamia R.Br., Chenopodium-Amaranthus and Humulus. This study provides useful scientific information for production of specific allergen and for clinical prevention, specific diagnosis, specific therapy of allergic deseases.
