Study on Economic Evaluation of Coppice Forest of Black Locust Growing on Mountainous Region in Central-south Area, Shandong Province

The dynamic economic evaluation analysis was adopted to calculate the economic effectiveness of different rotation age of the coppice forest of black locust,while the economic maturity was determined with the help of sensitivity analysis.The results showed that no benefit would be derived from black locust coppice forest with a rotation age beyond 20; with a discounting rate not less than 12%, the investment on the coppice forest management on the Ⅲ land site is not reasonable;and the rotation age at the 8th to 13th years was reasonable for coppice forest management of black locust.
