Response of broadleaved Pinus koraiensis forests in Xiaoxinganling Mt. to global climate changea dynamic modeling

In this paper,the Forest Gap Model and four General Circulation Models (GCMs) were employed to investigate the dynamic response of broadleaved Pinus koraiensis forests in Xiaoxinganling Mountains of China to global climate change. Under CO\-2 doubling which was simulated by the scenarios of Oregon State University and Goddard Institute for Space Studies,the biomass of broadleaved Pinus koraiensis forest increased and the current Picea Abies broadleaved Pinus koraiensis forest would gradually develop to Betula costata Tilia amurensis Ulmus laciniata broadleaved Pinus koraiensis forest.Under the scenarios of Geophysical Fluid Dynamics Laboratory at Princeton University and United Kingdom Meteorological Office, Pinus koraiensis and other coniferous species would be replaced by broadleaved species such as Quercus mongolica,Tilia amurensis and Ulmus laciniata, and the broadleaved Pinus koraiensis forest would change to broadleaved forest,due to the great range increasing temperature by the scenarios.The future warming rate would determine the succession of broadleaved Pinus koraiensis forest.
