研究觀察1983年在南港所收集的空中孢粉，發現春天空中的孢粉種類及數量居全年之首，大 多爲樹種之花粉，例如：松樹、龍柏——杉木、楊梅、構樹、朴樹、女貞、茄冬、羅漢松、木麻黄 、山黃麻、相思樹及野桐等；柳樹及桑樹則多在冬末初春開花。夏天則多爲蕨類抱子，例如桫攞、 芒萁、蕨、腎蕨、瓦葦等屬及一些雜草的花粉，如薬科。秋天主耍的優勢槌有白轴子、植木、白干 庥及禾本科，以及一些雜存的花粉，如艾草、豬草及葎草等。冬天空中花粉種類少，多爲禾本科。 孢粉曆亦在文中一併被列出。

An investigation on airborne pollen during 1983 at Nankang, Taipei was undertaken. Pollen grains and fern spores encountered within an area of 3.24 cm* on a trap slide were counted and identified to genus level. The results show that the highest concentration of airborne pollen grains was found in the spring with a number of tree pollen: Pinus, Juniperus-Cuntiinghamia, Myrica， Broussonetia, Celtis, Ligustrum, Bischofia, Podocarpus, Casuarina, Trema, Acacia confttsa and Malhtus japonicus. Salix and Morus fitywer at the end of the winter or at the beginning of the spring. In the summer, many fern spores, namely Alsophila, Dicranopteris, Pteridium, Nephrolepis and Lepisorus and some weeds pollen, like Chenopodiaceae were recorded, while in the autumn Mallotus i>aniculatusy Alnus, Melaleuca and Gramineae were of dominant species. Some weed pollen of Artemisia, Ambrosia and Humulus were also found in the autumn. In the winter the dominant pollen species were Gramineae. A pollon calendar showing the occurring pollen and fern spore species during a year is demonstrated.
