Aeropalynological Study in Taipei County (Tan-Shui), 1993

淡水地區空中孢粉之研究

摘要


本實驗以英製孢粉收集器(Burkard seven-day volumetric recording trap)收集淡水地區1993年全年的空中孢粉,經由光學顯微鏡下鑑定和計數的結果發現,本地空中孢粉主要來源以風媒種類為主,只有少數來自蟲媒花。全年所有出現的孢粉種類中,裸子植物佔4科5屬,被子植物有57科88屬,而蕨類植物佔16科20屬。就數量而言,構樹屬(Broussonetia)花粉出現量佔全年總量的73.7%,為第一優勢花粉種類;次為山黃麻屬(Trema),佔7.4%;再次為苧麻屬(Boehmeria)和紫金牛屬(Ardisia),分別佔2.8%和2.4%。由逐日孢粉量分析反應出全年有二個明顯的主要花季:一為三月至五月(春季),為最重要的開花季節,豐富的孢粉量由各樹種花粉構成;另一為八月下旬至十月初(約在秋季),為時較短,主要由各草本花粉和蕨類孢子組成,其孢粉種類和孢粉數量,均無法與春季之孢粉量相提並論。由一日24小時孢粉量逐時變化趨勢(Diurnal variation)分析發現,有63%以上的種類,在上午達到當日出現量的高峰,顯示多數種類之花藥是受到白日溫度升高、相對濕度降低的氣象因子影響而開裂,並釋出花粉。構樹屬花粉在三月出現量高的數天內,在夜間另有高峰之出現量,根據氣象資料研判,此可能與夜間逆溫層之出現有關。由孢粉曆之建立,配合一日間孢粉最高量之出現時段,可提供淡水地區花粉過敏症研究之基本資料,以期發現可能導致過敏之孢粉種類。

並列摘要


An aeropalynological study was performed in the Tan-Shui area of Taipei County during 1993. A total of 128 taxa belonging to 77 families were identified. The dominant pollen were of genera Broussonetia (73.7%), Trema (7.4%), Boehmeria (2.8%), and Ardisia (2.4%). There were two major pollen seasons: March to May and August to October. The major pollen types changed with seasons: tree pollen in spring, fern spores with some weed pollen in summer and weed pollen in autumn. The majority of collected pollen were of anemophilous species. There existed a diurnal variation in the amount of airborne pollen within a day: with the highest peak occurring in the morning. On the basis of the present study, a pollen calendar was provided for the Tan-Shui area.
