林业上具有重要的生产和科学意义的长远计划是提高森林产量的问题。解决这个问题不仅与森林工业、农业生产活动有关,而且也与生物学、生态学、经济学等领域内的研究有关。不久前,森林产量的概念还仅仅被认为是木材,现在则把它包括在森林的全部功能内。森林最终产品的数量和品质,与合理利用森林程度有关。正因如此,不懂森林经营,而且在森林工业本身的一切领域内(采伐木材的、木材加工的、纤维造纸的工业等),都直接或间 The long-term plan for forestry that has important production and scientific implications is to raise forest production. To solve this problem is not only related to the forest industry and agricultural production activities, but also related to the researches in the fields of biology, ecology and economics. Not long ago, the notion of forest production was merely considered wood and is now included in the full function of the forest. The quantity and quality of forest final products are related to the rational use of forests. Because of this, we do not understand forest management, and in all areas of the forest industry itself (lumber harvesting, lumber processing, fiber papermaking, etc.), either directly or indirectly
