[Simulation of potential responses of clear-cut of mixed coniferous and broadleaved Korean pine forest in Yichun to climate change by BKPF model].

The potential responses of forest succession in the clear-cut site of mixed coniferous and broad-leaved Korean pine forest (MCBLKPF) in Yichun, Heilongjiang Province to global climate change and elevated CO2 after 50 years by BKPF model were simulated. The results indicated that the densities of Pinus koraiensis and hardwood species(Fraxinus mandshurica, Tilia amurensis, Juglans mandshurica and Phellodendron amurense) would increase, while the densities of Larix olgensis, Betula platyphylla and Populus davidiana would decrease after 50 years. The stand densities would be slightly lower than those at the same age under the current climate condition. The stand productivity, total aboveground biomass and leaf area index will increase by 7-28%, 15-24% and 5-8%, respectively. Climate change would be beneficial to the forest succession from the clear-cut site to MCBLKPF.
