Potential Impacts of Climate Change on Forests in China
1993
Deying Xu (Chinese Academy of Forestry, Beijing (China))
Experimental research on the physiology of tree seedlings under simulated climate and doubled carbon dioxide can rarely be extrapolated to grown forests. Climatological research has demonstrated a warming trend in the north and a cooling trend in the south of China. However, the changing climate has not caused the death of forests. Projecting the impact of climate change on forest distribution and growth using current GCMs seems to be the only method available.

Atmospheric pollutant can cause direct effects mediated by foliage and indirect effects mediated through soil. Biotic and abiotic factors can confound relationships among nutrient cycling, growth loss and mortality and air pollution. Changes in the soils could result from acidic deposition. Changes could include increased fertility as a result of sulphur and nitrogen input to soils that are deficient in these elements or decreased fertility through ion leaching or mobilization of toxic substances as aluminium.
