Analysing the Effects of Forest Structure on Carbon Stocks and Timber Production Under Changing Management and Climate

摘要: The growth of boreal forests in northern Europe is currently limited by a short growing season, low summer temperatures and supply nitrogen (Kellomaki et al., 1997; Nohrstedt, 2001; Olsson, 2006). Forest development expected to be affected the change climate response rapid increase greenhouse gases atmosphere, particularly carbon dioxide (CO 2 ) (IPCC, 2001). In Finland, future anticipated an 2–7°C annual mean temperature (T) 6–37% precipitation with concurrent doubling CO 2100 (Carter al. 2002). T may prolong season also enhance decomposition soil organic matter (SOM), thereby increasing (Melillo 1993; Lloyd & Taylor, 1994). These changes substantially forest growth, timber yield accumulation (C) (Giardina Ryan, 2000; Jarvis Linder, Luo Stromgren, Previous model-based studies applying current management regimes (“businessas-usual”) showed C stocks (both at stand/regional level) under changing (e.g. Pussinen However, there need adapt for altered dynamics ecosystem (Lindner, Furstenau 2007, Garcia-Gonzalo 2007a, b), order avoid harmful effects on optimally utilize increased these changes.
