一、问题的提出林道网是开发和经营森林的基础。建设合理的林道网,不仅可以大幅度地降低木材采运和营林成本,而且还对森林更新、森林抚育、森林资源综合利用、防治森林病虫害和森林火灾、振兴林区经济都起着巨大的促进作用。所谓建设合理林道网,就是指在林区所修建的道路的密度、配置、等级和次序合理。林道密度是指在单位面积上有多少林道,是林道网的量的指标。林道配置是指在一定的森林经营区域内林道是如何分布的,即林道的走向或位置。而林道的等级则是指林
First, the issue raised Lindau network is the basis for the development and management of forests. The rational construction of the forest road network not only can greatly reduce the cost of timber transportation and forest management, but also plays an important role in forest renewal, forest tending, comprehensive utilization of forest resources, prevention and control of forest pests and diseases and forest fires, and revitalization of forest economy enhancement. The so-called rational construction of Lindau network, refers to the construction of roads in the forest density, configuration, level and order is reasonable. The forest tract density is the number of forest roads per unit area, which is an indicator of the amount of forest road network. The forest road configuration refers to how the forest road is distributed within a certain forest management area, that is, the direction or position of the forest road. The forest level refers to the forest
