Impacts of Climate Change on Productivity of Forests in China Ⅱ.Geographic Distribution of Actual Productivity of Forests in China

In view of the relationship between productivity and climatic parameters,themodels of forest climatic productivity within China were developed based on the selecteddatum of forest net productivity versus the corresponding climatic variables,by which thedistributive pattern of the actual productivity of forests in China was successfully simulated.At the same time,the competerized maps of forest productivity within China predicted fromclimatic parameters were drawn by using the plotting software of climatic information.Theestablished models by means of the plotting software were allowed to be used to simulate andpredict the potential changes in growth and productivity of forests in China.
