摘要
本文研究了河北省北部地区国有林落叶松人工林林价.在立地分类的基础上,对落叶松人工林生长过程进行了分析,确定落叶松人工林最优采伐年龄为18～22a,根据造林和管理等营林成本计算,不同立地质量(11和13地位指数)的每立方米林价为68.22～84.25元,比育林基金多23.22～39.25元.
The study was conducted in national forest in north Hebei province plateau. According to analysis of the stand growth course and the wood quality, the optimum harvest cutting age is 18-22 years. Based on the cost of silviculture and administration the stumpage price is arround 68-85 yuans on different site quality (site indices 11-13) . It is higher than government silviculture foundation tax (23-40 yuans).
