梯带造林在国内外均有实践,是改变山地条件使之有利于农林业的一项有效措施。对于陡坡地营林机械化,本文提出与其新研制陡坡机械,不如将坡地改为水平梯带以推广现有机械的观点。编者认为,无论采取何种技术措施,都必须考虑其适用性,即从当时当地的条件来看,生产上是否可行,经济上是否合算,技术上是否先进,归根结底是看经济实效,甚至还要考虑到社会条件。原文及题目均较长,本刊作了某些删改,现发表供读者参考,并欢迎不同观点间展开讨论。 Ladder afforestation practices both at home and abroad, is an effective measure to change the mountain conditions conducive to agriculture and forestry. For steep slopes and mechanized forests, this paper proposes that instead of stepping up the newly developed steep slope machinery, it is better to change the slope to a horizontal ladder to promote the existing machinery. According to the editor, regardless of the technical measures taken, its applicability must be considered. From the local conditions at that time, whether it is viable for production, economically viable or technologically advanced is, in the final analysis, a matter of economic pragmatism and even Take into account social conditions. The original text and subject are longer, the journal made some of the censors, are published for readers reference, and welcome to discuss the different points of view.
