最近几十年来,由于种种原因而形成了大量的低价值林分。低价值林分是指林分组成不合理想、遭受了病虫害、遭受了破坏或疏密度低的林分。为了改善这些林分,就应当采取改造的措施。“林分改造”这个术语大约是1950年在森林经营活动中出现的,它由白俄罗斯林学家К.Ф.米龙所提倡。起初,他在低价值幼林内用播种和栽植较珍贵树种的方法,使低价值幼林转变为生产价值较高的林分。许多林业工作者如К.Ф.米龙等,他们都这样解释了这个术语,即林分改造的基本措施是在低价值林分整

In recent decades, a large number of low-value stands have been formed for various reasons. Low-value stands refer to stands that are not ideally composed, suffer from pests and diseases, have been damaged or have low density. In order to improve these stands, we should take measures to reform. The term “reforestation” appears about 1950 in forest management activities and was promoted by the Belarusian forest scientist КФФ. At first, he transformed low-value young forests into higher-producing stands by planting and planting more precious tree species in low-value young trees. Many forestry workers, such as К.Ф. Milon, etc., all interpret the term as such that the basic measure of forest rebuilding is to reorganize the forest at low value
