采伐与更新是森林经营的重要内容,采用的方式也是经营合理与否的最主要指标。建国三十多年来,我国森林采伐基本上只采用了大面积皆伐和择伐。这种状况很不适应我国广阔的地域,繁多的森林类型和材种类型。本译文介绍的渐伐,在国外正广泛地应用。这对某些(特别是阳性) 树种的天然更新,对保护森林环境及发挥森林防护效益有着极为重要的意义。在我国也有很多森林类型,像云冷杉林,落叶松林,红松林等也都可以考虑应用渐伐。
Harvesting and updating is an important part of forest management. The mode adopted is also the most important indicator of whether the operation is reasonable or not. Over the past 30 years since the founding of the People’s Republic of China, basically only only a large area of clear cutting and selective cutting has been used for forest logging in our country. This situation is not suited to our vast geographical area, a wide range of forest types and types of species. The translation introduced in this translation is widely used in foreign countries. This natural regeneration of some (especially positive) tree species is extremely important for the protection of the forest environment and the protection of the forest. In our country, there are many forest types, such as spruce forest, larch forest, korean pine forest, etc. can also consider the application of cutting.
