Comparative analysis of the influence of climate change and nitrogen deposition on carbon sequestration in forest ecosystems in European Russia: simulation modelling approach
نویسنده
چکیده
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.

Land use/cover change is one of the main factors in environmental changes. The changes directly affect the value of ecosystem services. The purpose of this research is to evaluate the effect of land use/land cover change in the Kashkan area on its ecosystem services. This research was carried out in three stages, including the analysis of land cover changes, prediction of changes, and carbon st...
متن کاملComparison of Carbon and Nitrogen Sequestration in Soils Under Plantations, Natural Forest and Agricultural Farm Land Uses in Arjan Plain in the Fars Province
The carbon sequestaration by plants and soil is one of the easiest and the most econimical ways to reduce atmosphere carbon. This study was conducted on the planted land use of Fraxinus rotundifolia, Cupressus arizonica, obinia pseudoacacia L., Elaeagnus angustifolia, Cedrus libani, and Quercus brantii (persica) in the Arjan plain of Fars province. For each plantation land use, there were three...
