林道的修筑是林业生产的物质基础,林区道路网的合理密度和分布是开发新林区和加强老林区经营强度的重要技术经济措施。林道网密度代表着林业生产管理达到的现代化程度,在量纲上表示为单位经营林地面积上林道的长度。一、林道网的现状七十年代中期以前,我国林业主要采取以局轮伐集中开发的方式,林道主要是依据成、过熟林的分布、蓄积量而敷设和延伸。使林区道路密度形成疏密不均的状况。已开
The construction of forest road is the material basis of forestry production. The reasonable density and distribution of road network in forest area are the important technical and economic measures for developing new forest area and strengthening management intensity of old forest area. The density of forest road network represents the degree of modernization achieved in the management of forestry production and is dimensionally expressed as the length of forest road on the area of forest land per unit of business. I. Status of Lindau Network Before the mid-1970s, China’s forestry mainly adopted the method of centralized development by the Bureau of Rotation. The forest roads were mainly laid and extended according to the distribution and accumulation of mature and over-mature forests. So as to make the density of road density in the forest area uneven.
