上海东北部空中孢子花粉的初步研究

Preliminary Studies on Airborne Pollen Grains and Spores in the Northeastern Shanghai

本文初步报道上海东北部1989年5月—1991年4月连续2年收集空中孢粉的观察结果、共收集孢粉玻片1460张,鉴定、统计孢粉35551粒,区分出68种主要孢粉类型。对菌孢子中某些种可能是致敏原作了初步探讨,最后提出了本地区主要致敏植物花粉如构树、桑树、悬铃木(法国梧桐)、苦楝、白榆、枫杨、葎草、蒿属等,可供临床试用。

This is a preliminary report on the 2-year’s(1989.5-1991.4)survey results of airborne pollen and spores in Shanghai. We collected 1460 slides, from which we counted 35551 pollen grains and spores, and found 68 major types. There are 2“peak” months each year, showing that the pollen and spores dif-fusion frequency is of the largest density in April and September respec-tively, and that the early half of the year is dominated by arboreous pollen, while the later half is mainly herb pollen. The pollen species and pollen quantity correspond closely with the local vegetation conditions, again, the pol-len quantity varies somewhat from year to year due to weather conditions such as the qu-antity of rainfall, temperature, amount of sunshine, relative humidity, windy direction and wind velocity, etc. The Fungi which has been discussed as allergen, airborne allengic pol-len in Shanghai are mainly in Bronssonetia papyrirera, Morus spp., Platanus acerifolia, Melia azedarach, Ulmus pumila, Pterocarya stemoptera, Humulus scandens and Artemisia sp..
