| Zusammenfassung |
| An individual-based simulation model, EFIMOD, was used to simulate the
response of forest ecosystems to climate change and additional nitrogen
deposition. The general scheme of the model includes forest growth depending
on nitrogen uptake by plants and mineralization of soil organic matter. The
mineralization rate is dependent on nitrogen content in litter and forest
floor horizons. Three large forest areas in European Central Russia with a
total area of about 17 000 km2 in distinct environmental conditions
were chosen. Simulations were carried out with two climatic scenarios
(ambient climate and climate change) and different levels of nitrogen
deposition (ambient value and increase by 6 and
12 kg N ha−1 yr−1). The simulations showed that increased
nitrogen deposition leads to increased productivity of trees, increased
organic matter content in organic soil horizons, and an increased portion of
deciduous tree species. For the climate change scenario, the same effects on
forest productivity and similar shifts in species composition were predicted
but the accumulation of organic matter in soil was decreased. |
