摘要
通过森林经营划分将立地类型、森林现状、森林类型及经营措施有机地结合在一起,形成"树种(树种组)+坡度级+土壤厚度级+郁闭度级+亚林种(或二级地类)"的森林经营措施表。此编制方法,森林经营类型数量增多,考虑各类型各龄级面积,经营措施差异明显,且直观、易于操作又能定量管理,与当前常规林业经营措施相适应,为森林经营方案的编制服务。森林经营类型划分的基础材料直接来自于森林资源二类调查成果,因而经营类型可以直接作用于经营小(细)班,对林业生产有利。
Division of working group of silviculture is important to working scheme planning of silviculture. According to forest class, forest category, and land groups, working group of silviculture was divided gradually. Site type, status quo of forest, forest types, and working measures were organically combined to form the working measures structure of tree species, slope grade, .soil thickness grade, crown density class, and second stand type. The amount of working group of silviculture increased and each type and each age class area were considered. In addition, it was visual and easy to implement and manage quantitatively. Basis materials for working group of silviculture were from forestry resource survey, so working measures can be applied in to subcompartment production.
