| 英文摘要 | Abies fabric forest in the eastern slope of Gongga mountain is one type of subalpine dark coniferous forests of southwestern China. It is located on the southeastern edge of the Qinghai-Tibet plateau and is sensitive to climatic changes. A process-oriented biogeochemical model, Forest-DNDC, was applied to simulate the effects of climatic factors, temperature and precipitation changes on carbon characteristics, and greenhouse gases (GHGs) emissions in A. fabric forest. Validation indicated that the Forest-DNDC could be used to predict carbon characteristics and GHGs emissions with reasonable accuracy. The model simulated carbon fluxes, soil carbon dynamics, Soil CO(2), N(2)O, and NO emissions with the changes of temperature and precipitation conditions. The results showed that with variation in the baseline temperature from -2 degrees C to +2 degrees C, the gross primary production (GPP) and soil organic carbon (SOC) increased, and the net primary production (NPP) and net ecosystem production (NEP) decreased because of higher respiration rate. With increasing baseline precipitation the GPP and NPP increased slightly, and the NEP and SOC showed decreasing trend. Soil CO(2) emissions increased with the increase of temperature, and CO(2) emissions changed little with increased baseline precipitation. With increased temperature and decreased baseline temperature, the total annual soil N(2)O emissions increased. With the variation of baseline temperature from -2 degrees C to +2 degrees C, the total annual soil NO emissions increased. The total annual N(2)O and NO emissions showed increasing trends with the increase of precipitation. The biogeochemical simulation of the typical forest indicated that temperature changes strongly affected carbon fluxes, soil carbon dynamics, and soil GHGs emissions. The precipitation was not a principal factor affecting carbon fluxes, soil carbon dynamics, and soil CO(2) emissions, but changes in precipitation could exert strong effect on soil N(2)O and NO emissions. |
