Abstract: The carbon sequestration forests have important values of both carbon sequestration and timber harvest. The optimal rotation is an important factor that effects the benefits of carbon sequestration forests, which have been rarely studied. In this paper we focused on the short rotation carbon sequestration forests of eucalypt in Cangnan County, Zhejiang Province, and built an optimal rotation evaluation model of the carbon sequestration forests accounting for carbon price, discount rate, timber price and labor price under various scenarios and infinite horizon. We studied how above variables influence the optimal rotation of the carbon sequestration forests and discussed the net value of carbon sequestration forests benefits, through simulation calculation using the growth model of eucalypt. The results showed that when the carbon price was 55 Yuan/t, discount rate was 5%, timber price was 700 Yuan/m3 and labor price was 100 Yuan each day, the optimal rotation of eucalypt carbon sequestration forests was 8 years, the net present value of per unit area was 99 053.80 Yuan/ha, but carbon sequestration benefits only accounted for 8.60% of the total net present value. In addition, the carbon price, discount rate and timber price had negative correlations with the optimal rotation of carbon sequestration forests, while the labor price had a positive correlation.

Key words: Eucalypt, Carbon sequestration forest, optimal rotation
