对于用同龄法为长期木材生产服务的林区,其经营目标通常可用面积控制法实现稳产。简言之,实现这一目标是通过各树龄组的均匀分布,然后从最大树龄开始每年采伐大致相等的面积。这样便可以保持比较毖定的木材产量。 For forest areas that use the same-age approach to serve long-term timber production, their business objectives are usually stabilized with area control. In short, this goal is achieved through the uniform distribution of tree-age groups and then harvesting roughly the same area annually from the maximum age. In this way, we can maintain a relatively stable timber output.
