Abstract:

Based on Chinese Fir Growth Model and the improved model of Faustmann-Hartman,Chinese fir in Jiangxi Province was taken for the research object to compare LEV and optimal rotation period of Chinese fir under different sites,different carbon prices and different interest rates.The results show that due to the current wood prices far higher than the price of carbon sinks,composite target under the carbon sink forest management does not change the Chinese fir optimal rotation period and the carbon price does not affect Chinese fir optimal rotation obviously,and the interest rates and Cunninghamialanceolata optimal rotation turn into negative correlation.At the same time,the expected value of Chinese fir forest based on carbon sink management is larger than that of single objective,and the expected value of forest land is increasing rapidly,which means that the investment management of carbon sink forest can be considered in the process of forest management.

Key words: optimal rotation period, forestland expected value, forest carbon sinks, Chinese fir
