Samples of the moss Hypnum cupressiforme were collected at 103 locations in forests of Slovenia. At each location, samples were taken at two types of sites: under tree canopies and in adjacent forest openings. The results show that the moss collected in the forest openings reflects the surrounding land-use characteristics and, consequently, the main N emission sources. For moss sampled under canopies, the characteristics of the forest at the moss-sampling locations are more important than the main emission sources outside the forest. A regression model was used to provide the nitrogen (N) concentration in moss from the forest openings in relation to the N concentration in moss under canopies and other environmental variables. The spatial distribution of the locations of the N concentrations and δ(15)N values in moss collected in the forest openings and under the canopies in relation to main N deposition sources is discussed.
在斯洛文尼亚的森林中，于 103 个地点采集了藓类植物杯藓样本。在每个地点，均在两种类型的地点采集样本：树冠下和相邻的林窗中。结果表明，在林窗中采集的苔藓反映了周围的土地利用特征，因此也是主要的氮排放源。对于在树冠下采集的苔藓样本而言，在苔藓采样地点的森林特征比森林外的主要排放源更为重要。使用回归模型，提供了与树冠下苔藓的氮浓度和其他环境变量有关的林窗中苔藓的氮浓度。讨论了与主要氮沉降源相关的林窗中以及树冠下采集的苔藓的氮浓度和 δ(15)N 值的位置的空间分布。
