林区道路是开发建设林区,全面合理经营森林的物质基础,也是实现林业现代化的必要条件。为了探讨滇南云南松林区伐区路网密度,我们选择坚持十八年伐区工艺设计的南盘江林业局作调查研究。南盘江局是我省开发较早的一个老局,于五八年建局至今共生产木材120万m~3,采伐面积21719公顷,林业局经营总面积104275公顷,
The roads in the forest area are the material basis for the development and construction of forest areas and for the comprehensive and reasonable management of forests.
