摘要

The determination of atmospheric deposition in forests can be accomplished using technical sampling devices, bioindicators or modelling. Since 1990, the European Moss Survey has been providing data on element concentrations in moss every five years at up to 7,300 sampling sites. In the moss specimens, heavy metals (HM), nitrogen (N, since 2005) and persistent organic pollutants (POPs, since 2010) were determined. Germany participated in all surveys with the exception of that in 2010. For the Moss Survey 2015, the monitoring network 2005 was re-organised. In this study, a new decision support method for multi-criteria optimization is presented. It is demonstrated by use of data collected in 2005 that the computer-integrated model enables network reorganization with high efficiency and reproducibility. Its application yielded a network with a reduction of sample points from 726 to 402 without significant loss in statistical validity and geostatistical representativity of the measured element concentrations in moss and, respectively, harmonization with other environmental monitoring networks.
