摘要

Within roughly 4 ha of a typical spruce forest of the central Black Forest differences between six soil types of 7.31 kg N_2O-N and 377.24 kg CH_4-C ha~(-1) a~(-1) have been measured in the year 2001. The different water and redox regimes are responsible for both , the differentiation of the soils and the trace gas fluxes. The assumption that each soil type has distinct gas fluxes has been proven. Therefore we recommend soil maps to be used for area calculations of nitrous oxide and methane fluxes from forest ecosystems.
