建国后,我国的森林经理方法,基本上是按龄级法组织规划森林经营的。所谓龄级法是由法正林的理论应孕而生的,其主要特点是先把森林资源特性相同,经营方向一致的小班组成一个独立的经营单位,称为森林经营类型(或叫作业级),就其内部结构而言,不同经营类型的立地质量,生态特征,林分结构,以及龄级分布等,是各具特征的。龄级法要求按照经营类型内部的龄级顺序,把最近应当采伐的老令林,纳入经理期,采伐面积依法正林的龄级结构与现实林的差异,加以调整,以寻求实现永续利用的龄级结构。实践证明,这种森林经理的方法对于实现我国林业的采育结合,森林资源的合理结构,永续利用,都具有指导意义。龄级法也早为世界各国森林经理广为采用,并取得明显的效果,以西德为例,目前该国森林覆被率29%,每公顷的蓄积量、生长量
After the founding of the People’s Republic of China, the method of forest managers in our country basically plans and manages forest management according to the age-class law. The so-called age-class law is the theory of Fa-Lin should be born, its main feature is the first of the same characteristics of forest resources, operating in the same direction of small groups to form an independent business unit, known as the type of forest management (or job-level ), In terms of their internal structure, the site quality, ecological characteristics, stand structure and age distribution of different management types are all characteristic. The age-level law requires that senior-level relics to be deforested be included in the management period, according to the order of age class within the operating type, be adjusted according to the difference between the age-class structure and the actual forest of the deforestation in order to seek sustainable development Age structure. Practice has proved that this method of forest managers for the realization of China’s forestry combination of harvesting, the rational structure of forest resources, sustainable use, have guiding significance. Age class law as early as forest managers in various countries around the world widely used and achieved significant results, with West Germany as an example, the current forest cover rate of 29%, the accumulation of per hectare, growth
