Abstract The pollen spectra of air and surface soil samples from a rooftop (at 14 m) and from ground level (at 1.6 m) in the suburbs of Vienna (Austria) were compared. Two soil samples and two air samples were taken on four different days to account for possible differences: in winter when no pollination occurred (reference day), in spring during the main flowering of Betula (birch day), in spring/summer during the main flowering of Poaceae (grass day), and in autumn during the main flowering of Ambrosia (ragweed day). Thirty-five different pollen types were used to describe the pollen spectra. Frequencies of certain pollen types reflect a seasonal impact on both the surface soil and air samples and show a similarity between air and soil samples on most of the days. However, the seasonal impact is higher in the air samples and shows a high consistency for ground and rooftop level. Kendall’s tau correlation coefficients further substantiate the similarities of the samples especially for the pollen season days. Exceptions include the winter day when pollination was low and the air samples recorded nearly no pollen at all, and the ragweed day when Ambrosia pollen was abundant in three of four samples but not in the ground surface soil sample. Thus, (1) air and surface pollen samples record similar signals during the pollen season but not during the ragweed and winter season and (2) air and surface pollen samples show the impact of local vegetation also in pollen traps located at different heights.

空气和地表土壤样本——两双不同的鞋子?比较花粉季节不同天的花粉光谱

摘要 比较了维也纳(奥地利)郊区屋顶(14 m)和地面(1.6 m)的空气和表层土壤样品的花粉光谱。在四个不同的日子里采集了两个土壤样本和两个空气样本以考虑可能的差异:在没有授粉发生的冬季(参考日),在桦木主要开花期(桦树日)的春季,在主要开花期的春季/夏季禾本科(草日)开花,秋季在豚草主要开花期(豚草日)。使用 35 种不同的花粉类型来描述花粉光谱。某些花粉类型的频率反映了对表层土壤和空气样本的季节性影响,并且在大多数日子里显示了空气和土壤样本之间的相似性。然而,空气样本的季节性影响更大,并显示出地面和屋顶高度的高度一致性。Kendall 的 tau 相关系数进一步证实了样品的相似性,尤其是在花粉季节。例外情况包括授粉率低且空气样本几乎没有记录到任何花粉的冬日,以及豚草花粉在四个样本中的三个样本中丰富但在地表土壤样本中不丰富的日子。因此,(1) 空气和地表花粉样本在花粉季节记录了类似的信号,但在豚草和冬季期间没有记录,(2) 空气和地表花粉样本显示了当地植被也在位于不同高度的花粉陷阱中的影响。Kendall 的 tau 相关系数进一步证实了样品的相似性,尤其是在花粉季节。例外情况包括授粉率低且空气样本几乎没有记录任何花粉的冬日,以及豚草花粉在四个样本中的三个样本中含量丰富但在地表土壤样本中不丰富的日子。因此,(1) 空气和地表花粉样本在花粉季节记录了类似的信号,但在豚草和冬季期间没有记录,(2) 空气和地表花粉样本显示了当地植被也在位于不同高度的花粉陷阱中的影响。Kendall 的 tau 相关系数进一步证实了样品的相似性,尤其是在花粉季节天数。例外情况包括授粉率低且空气样本几乎没有记录任何花粉的冬日,以及豚草花粉在四个样本中的三个样本中含量丰富但在地表土壤样本中不丰富的日子。因此,(1) 空气和地表花粉样本在花粉季节记录了类似的信号,但在豚草和冬季期间没有记录,(2) 空气和地表花粉样本显示了当地植被也在位于不同高度的花粉陷阱中的影响。豚草花粉在四个样品中的三个样品中含量丰富,但在地表土壤样品中不含量。因此,(1) 空气和地表花粉样本在花粉季节记录了类似的信号,但在豚草和冬季期间没有记录,(2) 空气和地表花粉样本显示了当地植被也在位于不同高度的花粉陷阱中的影响。豚草花粉在四个样品中的三个样品中含量丰富,但在地表土壤样品中不含量。因此,(1) 空气和地表花粉样本在花粉季节记录了类似的信号,但在豚草和冬季期间没有记录,(2) 空气和地表花粉样本显示了当地植被也在位于不同高度的花粉陷阱中的影响。
