Aerobiological studies in urban areas are quite abundant in recent decades, but not in rural areas with a high environmental value. In this work, we analyze the airborne levels of pollen and fern spores in year 2012 collected by means of a volumetric sampler located in an ecological vineyard and in the Biosphere Reserve “Sierras de Béjar y Francia.” The results showed a high atmospheric representation of the natural vegetation of the environment, with almost half of the airborne pollen coming from the most represented tree formations such as chestnut and oak trees. Airborne concentrations of grass pollen reached approximately a 25% of the total, with high levels during 33 days of the year, 18 of them in January, February and March. The seasonal and intradaily behavior of the most abundant pollen types was focused on the months of May, June and July and the central hours of the day, respectively. Temperature had a positive influence on the levels of the main pollen types, while rainfall had a negative effect on pollen types from herbaceous species.

生物圈保护区“Sierras de Béjar y Francia”（MW 西班牙）中的空气生物学记录

近几十年来，城市地区的空气生物学研究相当丰富，但在具有高环境价值的农村地区则不然。在这项工作中，我们分析了 2012 年通过位于生态葡萄园和生物圈保护区“Sierras de Béjar y Francia”中的体积采样器收集的花粉和蕨类孢子的空气传播水平。结果表明，环境中的自然植被具有很高的大气代表性，几乎一半的空气传播花粉来自最具代表性的树群，如栗树和橡树。空气中草花粉的浓度达到了总量的 25% 左右，一年中有 33 天的高浓度，其中 18 天是在 1 月、2 月和 3 月。最丰富的花粉类型的季节性和日内行为集中在五月，分别是六月和七月以及一天中的中心时间。温度对主要花粉类型的水平有积极影响，而降雨对草本植物的花粉类型有负面影响。
