利用七日式花粉定量捕捉器在台南市進行兩年空中孢粉調查。總共收集到14,232顆種子植物的花粉粒，平均花粉濃度為每立方米1.35粒。在一年之中，空中花粉數量以春季最高，冬季最低；在台南地區，空中花粉的主要供應者為都市及公園中的植物種類。調查結果指出最重要的花粉種類分別屬於Broussonetia (39.10%)、Gramineae(10.15%)、Casuarinaequisetifolia(6.68%)、Artrocarpus(5.50%)、Chenopodiaceae(5.19%)、Macaranga(4.70%)、Alnus(4.40%)、Typha(3.91%)、Humulus scandens(2.66%)和Compositae(2.46%)；其中構成木本的花粉大部分來自於金縷梅亞綱的植物。在台南市重要的花粉種類中，構樹為最主要的組成分子，和全省其他花粉站的研究報告相似。且其花粉具致過敏性，當為台灣臨床過敏學者所注意。

　　　　　An investigation of airborne pollen concentration was conducted in two consecutive yearsin Tainan, Taiwan, by using a Burkard seven-day volumetric recording trap. A total of 14,232 pollengrains of seed plants were counted. The mean of pollen concentration was 1.35 grains/m　. In thecourse of a year , airborne pollen was most abundant in spring (late March of May) and least inautumn (from September to November). Most of the pollen grains collected were contributed byurban vegetation and garden trees. The important pollen taxa were Broussonetia (39.10%),Gramineae (10.15%), Casuarina equisetifolia (6.68%), Artrocarpus (5.50%), Chenopodiaceae(5.19%), Macaranga tanarius (4.70%), Alnus formosana (4.40%), Typha angustifolia (3.91%),Humulus scandens (2.66%) and Compositae (2.46%). In the above taxa, the main contributors oftree pollen are members of subclass Hamamelidae. Broussonetia is increasingly important inaeropalynological studies in Taiwan for its high pollen concentration reported in this study as well asmany other recent investigations.
