林种标志着一个林区或基层林业单位的森林在国民经济中的作用和经营目的。森林经营中的一切重大问题,如造林树种和方式的选定,抚育改造的方式和强度以及采伐方式和成熟龄的确定等,都要以林种为前提。因此,对林种问题需进行认真研究。 Forests indicate the role and management purpose of the forest in a forest or grass-roots unit in the national economy. All major issues in forest management, such as the selection of tree species and methods for afforestation, the ways and intensities of tending and transformation, and the determination of harvesting methods and maturity ages, must all be based on forest species. Therefore, the issue of forest species needs to be carefully studied.
