我国森林法明确提出“以营林为基础,普遍护林,大力造林,采育结合,永续利用”的林业建设方针。为了实现森林资源永续利用,要求对一定范围内的森林资源在人为的保护、培育、发展措施下实现越来越多越来越好。这集中反映一个如何确定利用规模和森林年伐量问题。它是一项关系森林开发后生态效益、社会效益和经济效益的关键指标。对已开发的老林区,合理确定年采伐规模对焕发林区青春实现长期经营提高经济效益同样有着重要作用。
The forest law of our country clearly put forward the policy of forestry construction based on “afforestation, universal forest protection, afforestation, combination of harvesting and sustainable development”. In order to realize the sustainable use of forest resources, it is required to realize more and more and better and better under the artificial protection, cultivation and development measures of forest resources within a certain range. This focuses on how to determine the scale of utilization and annual forest cutting. It is a key indicator of the ecological, social and economic benefits of forest development. As for the old forest areas that have been developed, it is equally important to rationally determine the annual scale of logging to rejuvenate forest youth to achieve long-term management and economic benefits.
