Effects of Climate Change and Fire on Carbon Storage in North American Boreal Forests

摘要: There is little doubt in the scientific community that if current patterns of climate warming continue, there will be dramatic changes distribution vegetation and forest cover throughout boreal region. Most research has concentrated on predicting how rises air temperature (1) cause shifts carbon balance terrestrial biome (Smith Shugart 1993) or (2) change rates soil respiration (Townsend et al. 1992; Randerson 1996; Thompson 1997). Recently, more sophisticated biogeochemical cycling models have been developed actually model processes responsible for storage to assess budget over large areas (Haxeltine Prentice McGuire 1997; Peng 1998). None these approaches takes into consideration effects fire longer-term forest.
