森林是国家重要的自然历史资源。在社会发展的进程中天然的森林资源被逐步采伐利用,其经营面积和森林的蓄积在不断的减少,而人工林逐渐增加。建国初期营造的人工林,现已成林成材,当前,如何经营管理好人工林资源,仍是林业生产建设中的一个重要问题。 The forest is an important national natural historical resource. In the process of social development, natural forest resources are gradually harvested and utilized, and the area under their management and the accumulation of forests are continuously decreasing while the plantation forests are gradually increasing. At the beginning of the founding of the People’s Republic of China, plantation forests were now under construction. At present, how to manage and manage plantation resources is still an important issue in forestry production and construction.
